+We are extremely grateful to [DMIT](https://dmit.io) and [Misaka](https://misaka.io) and [Skywolf](https://skywolf.cloud) for providing the network infrastructure that powers this project.
+
+## Announcement
+
+LeoMoeAPI v1 will end service support on September 1, 2024. Versions **v1.1.7** and below that rely on its service will become unusable. Please download from the [Ntrace-V1 repository](https://github.com/nxtrace/Ntrace-V1/releases) NextTrace.
+
+Because NextTrace V1 and V2 are branches with differing development philosophies, each is currently managed by an internal Owner focusing on different aspects. These branches cater to developers with varying needs. Now, the [V1](https://github.com/nxtrace/Ntrace-V1/) and [V2](https://github.com/sjlleo/MoeTrace) branch has established its own separate repository. For a considerably long period in the future, we plan to maintain the development and upkeep of both branches simultaneously.

 ## How To Use

+Document Language: English | [简体中文](README_zh_CN.md)
+
+Currently, **V2 version** is a completely redesigned project and is recruiting beta testers for this revamped version. If you are interested, please check out [sjlleo/MoeTrace](https://github.com/sjlleo/MoeTrace).
+
+For the **enhanced version of V1**, please visit [nxtrace/Ntrace-V1](https://github.com/nxtrace/Ntrace-V1).

+    Please note, the repositories for all of the above installation methods are maintained by open source enthusiasts. Availability and timely updates are not guaranteed. If you encounter problems, please contact the repository maintainer to solve them, or use the binary packages provided by the official build of this project.
+
+### Manual Install
+* Download the precompiled executable
+
+    For users not covered by the above methods, please go directly to [Release](https://github.com/nxtrace/Ntrace-V1/releases/latest) to download the compiled binary executable.
+
+    * `Release` provides compiled binary executables for many systems and different architectures. If none are available, you can compile it yourself.
+    * Some essential dependencies of this project are not fully implemented on `Windows` by `Golang`, so currently, `NextTrace` is in an experimental support phase on the `Windows` platform.
+
+* Install from source
+
+    After installing Go >= 1.20 yourself, you can use the following command to install
+
+    ```shell
+    go install github.com/nxtrace/Ntrace-V1@latest
+    ```
+    After installation, the executable is in the `$GOPATH/bin` directory. If you have not set `GOPATH`, it is in the `$HOME/go/bin` directory.

- `Release`里面为很多系统以及不同架构提供了编译好的二进制可执行文件，如果没有可以自行编译。
- 一些本项目的必要依赖在`Windows`上`Golang`底层实现不完全，所以目前`NextTrace`在`Windows`平台不可用。

 ### Get Started

-`NextTrace` 默认使用`ICMP`协议发起`TraceRoute`请求，该协议同时支持`IPv4`和`IPv6`
+`NextTrace` uses the `ICMP` protocol to perform TraceRoute requests by default, which supports both `IPv4` and `IPv6`

 ```bash
 # IPv4 ICMP Trace
 nexttrace 1.0.0.1
+# URL
+nexttrace http://example.com:8080/index.html?q=1

-# 表格打印（一次性输出全部跳数，需等待20-40秒）
-nexttrace -table 1.0.0.1
+# Form printing
+nexttrace --table 1.0.0.1
+
+# An Output Easy to Parse
+nexttrace --raw 1.0.0.1
+nexttrace --json 1.0.0.1
+
+# IPv4/IPv6 Resolve Only
+nexttrace --ipv4 g.co
+nexttrace --ipv6 g.co

 # IPv6 ICMP Trace
 nexttrace 2606:4700:4700::1111
+
+# Disable Path Visualization With the -M parameter
+nexttrace koreacentral.blob.core.windows.net
+# MapTrace URL: https://api.leo.moe/tracemap/html/c14e439e-3250-5310-8965-42a1e3545266.html
 ```

-`NextTrace` 现已经支持快速测试，有一次性测试回程路由需求的朋友可以使用
+PS: The routing visualization drawing module was written by [@tsosunchia](https://github.com/tsosunchia), and the specific code can be viewed at [tsosunchia/traceMap](https://github.com/tsosunchia/traceMap).
+
+Note that in LeoMoeAPI 2.0, due to the addition of geographical location data, **we have deprecated the online query part of the OpenStreetMap API in the traceMap plugin and are using location information from our own database**.
+
+The routing visualization function requires the geographical coordinates of each Hop, but third-party APIs generally do not provide this information, so this function is currently only supported when used with LeoMoeAPI.
+
+`NextTrace` now supports quick testing, and friends who have a one-time backhaul routing test requirement can use it
+
 ```bash
-# 北上广（电信+联通+移动+教育网）IPv4 ICMP 快速测试
-nexttrace -f
+# IPv4 ICMP Fast Test (Beijing + Shanghai + Guangzhou + Hangzhou) in China Telecom / Unicom / Mobile / Education Network
+nexttrace --fast-trace

-# 也可以使用 TCP SYN 而非 ICMP 进行测试
-nexttrace -f -T
+# You can also use TCP SYN for testing
+nexttrace --fast-trace --tcp
 ```

-`NextTrace` 也可以使用`TCP`和`UDP`协议发起`Traceroute`请求，不过目前只支持`IPv4`
+`NextTrace` already supports route tracing for specified Network Devices
+
+```bash
+# Use eth0 network interface
+nexttrace --dev eth0 2606:4700:4700::1111
+
+# Use eth0 network interface's IP
+# When using the network interface's IP for route tracing, note that the IP type to be traced should be the same as network interface's IP type (e.g. both IPv4)
+nexttrace --source 204.98.134.56 9.9.9.9
+```
+
+`NextTrace` can also use `TCP` and `UDP` protocols to perform `Traceroute` requests, but `UDP` protocols only supports `IPv4` now

 ```bash
 # TCP SYN Trace
-nexttrace -T www.bing.com
+nexttrace --tcp www.bing.com

-# 可以自行指定端口[此处为443]，默认80端口
-nexttrace -T -p 443 1.0.0.1
+# You can specify the port by yourself [here is 443], the default port is 80
+nexttrace --tcp --port 443 2001:4860:4860::8888

 # UDP Trace
-nexttrace -U 1.0.0.1
+nexttrace --udp 1.0.0.1

-nexttrace -U -p 53 1.0.0.1
+nexttrace --udp --port 53 1.0.0.1
 ```

-`NextTrace`也同样支持一些进阶功能，如 IP 反向解析、并发数控制、模式切换等
+`NextTrace` also supports some advanced functions, such as ttl control, concurrent probe packet count control, mode switching, etc.

 ```bash
-# 每一跳发送2个探测包
-nexttrace -q 2 www.hkix.net
+# Send 2 probe packets per hop
+nexttrace --queries 2 www.hkix.net

-# 无并发，每次只发送一个探测包
-nexttrace -r 1 www.hkix.net
+# No concurrent probe packets, only one probe packet is sent at a time
+nexttrace --parallel-requests 1 www.hkix.net

-# 打开IP反向解析功能，在IPv6的骨干网定位辅助有较大帮助
-nexttrace -rdns www.bbix.net
+# Start Trace with TTL of 5, end at TTL of 10
+nexttrace --first 5 --max-hops 10 www.decix.net

-# 特色功能：打印Route-Path图
-# Route-Path图示例：
-# AS6453 塔塔通信「Singapore『Singapore』」
+# Turn off the IP reverse parsing function
+nexttrace --no-rdns www.bbix.net
+
+# Set the payload size to 1024 bytes
+nexttrace --psize 1024 example.com
+
+# Feature: print Route-Path diagram
+# Route-Path diagram example:
+# AS6453 Tata Communication「Singapore『Singapore』」
 #  ╭╯
 #  ╰AS9299 Philippine Long Distance Telephone Co.「Philippines『Metro Manila』」
 #  ╭╯
 #  ╰AS36776 Five9 Inc.「Philippines『Metro Manila』」
 #  ╭╯
-#  ╰AS37963 阿里云「ALIDNS.COM『ALIDNS.COM』」
-nexttrace -report www.time.com.my
+#  ╰AS37963 Aliyun「ALIDNS.COM『ALIDNS.COM』」
+nexttrace --route-path www.time.com.my
 ```

-`NextTrace`支持用户自主选择 IP 数据库（目前支持：`LeoMoeAPI`, `IP.SB`, `IPInfo`, `IPInsight`, `IPAPI.com`）
+`NextTrace` supports users to select their own IP API (currently supports: `LeoMoeAPI`, `IP.SB`, `IPInfo`, `IPInsight`, `IPAPI.com`, `Ip2region`, `IPInfoLocal`, `CHUNZHEN`)

 ```bash
-# 可以自行指定IP数据库[此处为IP.SB]，不指定则默认为LeoMoeAPI
-nexttrace -d IP.SB
-## 特别的：其中 ipinfo API 需要从ipinfo自行购买服务，如有需要可以clone本项目添加其提供的token自行编译
-##        TOKEN填写路径：ipgeo/tokens.go
-## 另外：由于IP.SB被滥用比较严重，会经常出现无法查询的问题，请知悉。
-##      IPAPI.com限制调用较为严格，如有查询不到的情况，请几分钟后再试。
+# You can specify the IP database by yourself [IP-API.com here], if not specified, LeoMoeAPI will be used
+nexttrace --data-provider ip-api.com
+## Note There are frequency limits for free queries of the ipinfo and IPInsight APIs. You can purchase services from these providers to remove the limits
+##      If necessary, you can clone this project, add the token provided by ipinfo or IPInsight and compile it yourself
+## Note For the offline database IPInfoLocal, please download it manually and rename it to ipinfoLocal.mmdb. (You can download it from here: https://ipinfo.io/signup?ref=free-database-downloads)
+##      For the offline database Ip2region, you can download it manually and rename it to ip2region.db, or let NextTrace download it automatically
+## Fill the token to: ipgeo/tokens.go
+## Please be aware: Due to the serious abuse of IP.SB, you will often be not able to query IP data from this source
+## IP-API.com has a stricter restiction on API calls, if you can't query IP data from this source, please try again in a few minutes
+
+# The Pure-FTPd IP database defaults to using http://127.0.0.1:2060 as the query interface. To customize it, please use environment variables
+export NEXTTRACE_CHUNZHENURL=http://127.0.0.1:2060
+## You can use https://github.com/freshcn/qqwry to build your own Pure-FTPd IP database service
+
+# You can also specify the default IP database by setting an environment variable
+export NEXTTRACE_DATAPROVIDER=ipinfo
 ```

-`NextTrace`支持参数混合使用
+`NextTrace` supports mixed parameters and shortened parameters

 ```bash
 Example:
-nexttrace -d IPInsight -m 20 -p 443 -q 5 -r 20 -rdns 1.1.1.1
-nexttrace -T -q 2 -r 1 -rdns -table -report 2001:4860:4860::8888
+nexttrace --data-provider IPAPI.com --max-hops 20 --tcp --port 443 --queries 5 --no-rdns 1.1.1.1
+nexttrace -tcp --queries 2 --parallel-requests 1 --table --route-path 2001:4860:4860::8888
+
+Equivalent to:
+nexttrace -d IPAPI.com -m 20 -T -p 443 -q 5 -n 1.1.1.1
+nexttrace -T -q 2 --parallel-requests 1 -t -R 2001:4860:4860::8888
 ```

-### IP 数据库
+### IP Database

-目前使用的 IP 数据库默认为我们自己搭建的 API 服务，如果后期遇到滥用，我们可能会选择关闭。
+#### We use [bgp.tools](https://bgp.tools) as a data provider for routing tables.

-我们也会在后期开放服务端源代码，您也可以根据该项目的源码自行搭建属于您的 API 服务器。
+NextTrace BackEnd is now open-source.

-NextTrace 所有的的 IP 地理位置`API DEMO`可以参考[这里](https://github.com/xgadget-lab/nexttrace/blob/main/ipgeo/)

-## FAQ 常见问题
+`OpenTrace` is the cross-platform `GUI` version of `NextTrace` developed by @Archeb, bringing a familiar but more powerful user experience.

-如果你在安装或者使用的时候遇到了问题，我们建议你不要把新建一个 `issue` 作为首选项
+This software is still in the early stages of development and may have many flaws and errors. We value your feedback.

+
+## LeoMoeAPI Credit
+
+NextTrace focuses on Golang Traceroute implementations, and its LeoMoeAPI geolocation information is not supported by raw data, so a commercial version is not possible.
+
+The LeoMoeAPI data is subject to copyright restrictions from multiple data sources, and is only used for the purpose of displaying the geolocation of route tracing.
+
+1. We would like to credit samleong123 for providing nodes in Malaysia, TOHUNET Looking Glass for global nodes, and Ping.sx from Misaka, where more than 80% of reliable calibration data comes from ping/mtr reports.
+
+2. At the same time, we would like to credit isyekong for their contribution to rDNS-based calibration ideas and data. LeoMoeAPI is accelerating the development of rDNS resolution function, and has already achieved automated geolocation resolution for some backbone networks, but there are some misjudgments. We hope that NextTrace will become a One-Man ISP-friendly traceroute tool in the future, and we are working on improving the calibration of these ASN micro-backbones as much as possible.
+
+3. In terms of development, I would like to credit missuo and zhshch for their help with Go cross-compilation, design concepts and TCP/UDP Traceroute refactoring, and tsosunchia for their support on TraceMap.
+
+4. I would also like to credit FFEE_CO, TheresaQWQ, stydxm and others for their help. leoMoeAPI has received a lot of support since its first release, so I would like to credit them all!
+
+We hope you can give us as much feedback as possible on IP geolocation errors (see issue) so that it can be calibrated in the first place and others can benefit from it.

+
+由于 NextTrace V1 与 V2 分支是两个开发方向理念不完全相同的分支，目前由内部分别有一名 Owner 负责，各有其侧重点，面向不同需求的开发者，现 [V1](https://github.com/nxtrace/Ntrace-V1/) 和 [V2](https://github.com/sjlleo/MoeTrace) 分支分别已建立独立仓库，在未来相当长的一段时间里，我们会同时维护两个分支的开发与维护。
+
+## How To Use
+
+Document Language: [English](README.md) | 简体中文
+
+目前 **V2版本** 为全新的重构项目，其正在招募内测该重构版本的用户，若有意请查看 [sjlleo/MoeTrace](https://github.com/sjlleo/MoeTrace)。
+
+关于 **V1增强版本** 请转至 [nxtrace/Ntrace-V1](https://github.com/nxtrace/Ntrace-V1)。
+

+
+### Manual Install
+* 下载预编译的可执行程序
+    
+    对于以上方法没有涵盖的用户，请直接前往 [Release](https://github.com/nxtrace/Ntrace-V1/releases/latest) 下载编译后的二进制可执行文件。
+
+    * `Release`里面为很多系统以及不同架构提供了编译好的二进制可执行文件，如果没有可以自行编译。
+    * 一些本项目的必要依赖在`Windows`上`Golang`底层实现不完全，所以目前`NextTrace`在`Windows`平台出于实验性支持阶段。
+
+* 从源码安装
+
+    您可在自行安装Go >= 1.20后，使用以下命令安装
+
+    ```shell
+    go install github.com/nxtrace/Ntrace-V1@latest
+    ```
+    安装后可执行文件在`$GOPATH/bin`目录下，如果您没有设置`GOPATH`，则在`$HOME/go/bin`目录下。
+
+
+### Get Started
+
+`NextTrace` 默认使用`ICMP`协议发起`TraceRoute`请求，该协议同时支持`IPv4`和`IPv6`
+
+```bash
+# IPv4 ICMP Trace
+nexttrace 1.0.0.1
+# URL
+nexttrace http://example.com:8080/index.html?q=1
+
+# 表格打印，使用 --table / -t 参数，将实时显示结果
+nexttrace --table 1.0.0.1
+
+# 一个方便供机器读取转化的模式
+nexttrace --raw 1.0.0.1
+nexttrace --json 1.0.0.1
+
+# 只进行IPv4/IPv6解析
+nexttrace --ipv4 g.co
+nexttrace --ipv6 g.co
+
+# IPv6 ICMP Trace
+nexttrace 2606:4700:4700::1111
+
+# 禁用路径可视化 使用 --map / -M 参数
+nexttrace koreacentral.blob.core.windows.net
+# MapTrace URL: https://api.leo.moe/tracemap/html/c14e439e-3250-5310-8965-42a1e3545266.html
+```
+
+PS: 路由可视化的绘制模块由 [@tsosunchia](https://github.com/tsosunchia) 同学编写，具体代码可在 [tsosunchia/traceMap](https://github.com/tsosunchia/traceMap) 查看
+
+需要注意的是，在 LeoMoeAPI 2.0 中，由于新增了了地理位置数据，**我们已经弃用 traceMap 插件中 OpenStreetMap API 的在线查询的部分，并且使用自己数据库内的位置信息**。
+
+路由可视化功能因为需要每个 Hop 的地理位置坐标，而第三方 API 通常不提供此类信息，所以此功能目前只支持搭配 LeoMoeAPI 使用。
+
+`NextTrace` 现已经支持快速测试，有一次性测试回程路由需求的朋友可以使用
+
+```bash
+# 北上广（电信+联通+移动+教育网）IPv4 / IPv6 ICMP 快速测试
+nexttrace --fast-trace
+
+# 也可以使用 TCP SYN 而非 ICMP 进行测试
+nexttrace --fast-trace --tcp
+```
+
+`NextTrace` 已支持指定网卡进行路由跟踪
+
+```bash
+# 请注意 Lite 版本此参数不能和快速测试联用，如有需要请使用 enhanced 版本
+# 使用 eth0 网卡
+nexttrace --dev eth0 2606:4700:4700::1111
+
+# 使用 eth0 网卡IP
+# 网卡 IP 可以使用 ip a 或者 ifconfig 获取
+# 使用网卡IP进行路由跟踪时需要注意跟踪的IP类型应该和网卡IP类型一致（如都为 IPv4）
+nexttrace --source 204.98.134.56 9.9.9.9
+```
+
+`NextTrace` 也可以使用`TCP`和`UDP`协议发起`Traceroute`请求，不过目前`UDP`只支持`IPv4`
+
+```bash
+# TCP SYN Trace
+nexttrace --tcp www.bing.com
+
+# 可以自行指定端口[此处为443]，默认80端口
+nexttrace --tcp --port 443 2001:4860:4860::8888
+
+# UDP Trace
+nexttrace --udp 1.0.0.1
+
+# 可以自行指定端口[此处为5353]，默认53端口
+nexttrace --udp --port 5353 1.0.0.1
+```
+
+`NextTrace`也同样支持一些进阶功能，如 TTL 控制、并发数控制、模式切换等
+
+```bash
+# 每一跳发送2个探测包
+nexttrace --queries 2 www.hkix.net
+
+# 无并发，每次只发送一个探测包
+nexttrace --parallel-requests 1 www.hkix.net
+
+# 从TTL为5开始发送探测包，直到TTL为10结束
+nexttrace --first 5 --max-hops 10 www.decix.net
+
+# 关闭IP反向解析功能
+nexttrace --no-rdns www.bbix.net
+
+# 设置载荷大小为1024字节
+nexttrace --psize 1024 example.com
+
+# 特色功能：打印Route-Path图
+# Route-Path图示例：
+# AS6453 塔塔通信「Singapore『Singapore』」
+#  ╭╯
+#  ╰AS9299 Philippine Long Distance Telephone Co.「Philippines『Metro Manila』」
+#  ╭╯
+#  ╰AS36776 Five9 Inc.「Philippines『Metro Manila』」
+#  ╭╯
+#  ╰AS37963 阿里云「ALIDNS.COM『ALIDNS.COM』」
+nexttrace --route-path www.time.com.my
+```
+
+`NextTrace`支持用户自主选择 IP 数据库（目前支持：`LeoMoeAPI`, `IP.SB`, `IPInfo`, `IPInsight`, `IPAPI.com`, `Ip2region`, `IPInfoLocal`, `CHUNZHEN`)
+
+```bash
+# 可以自行指定IP数据库[此处为IP-API.com]，不指定则默认为LeoMoeAPI
+nexttrace --data-provider ip-api.com
+## 特别的: 其中 ipinfo 和 IPInsight API 对于免费版查询有频率限制，可从这些服务商自行购买服务以解除限制，如有需要可以 clone 本项目添加其提供的 token 自行编译
+##        TOKEN填写路径：ipgeo/tokens.go
+## 特别的: 对于离线库 IPInfoLocal，请自行下载并命名为 ipinfoLocal.mmdb (可以从这里下载：https://ipinfo.io/signup?ref=free-database-downloads)
+##        对于离线库 Ip2region 可NextTrace自动下载，也可自行下载并命名为 ip2region.db
+## 另外：由于IP.SB被滥用比较严重，会经常出现无法查询的问题，请知悉。
+##      IP-API.com限制调用较为严格，如有查询不到的情况，请几分钟后再试。
+
+# 纯真IP数据库默认使用 http://127.0.0.1:2060 作为查询接口，如需自定义请使用环境变量
+export NEXTTRACE_CHUNZHENURL=http://127.0.0.1:2060
+## 可使用 https://github.com/freshcn/qqwry 自行搭建纯真IP数据库服务
+
+# 也可以通过设置环境变量来指定默认IP数据库
+export NEXTTRACE_DATAPROVIDER=ipinfo
+```
+
+`NextTrace`支持使用混合参数和简略参数
+
+```bash
+Example:
+nexttrace --data-provider ip-api.com --max-hops 20 --tcp --port 443 --queries 5 --no-rdns 1.1.1.1
+nexttrace -tcp --queries 2 --parallel-requests 1 --table --route-path 2001:4860:4860::8888
+
+Equivalent to:
+nexttrace -d ip-api.com -m 20 -T -p 443 -q 5 -n 1.1.1.1
+nexttrace -T -q 2 --parallel-requests 1 -t -R 2001:4860:4860::8888
+```

+## IP 数据以及精准度说明
+
+对于IP相关信息的纠错反馈，我们目前开放了两个渠道：
+>- 本项目的GITHUB ISSUES区中的[IP 错误报告汇总帖](https://github.com/sjlleo/nexttrace/issues/41)
+>- 本项目的纠错专用邮箱: `correction@moeqing.com` （请注意此邮箱仅供IP相关信息纠错专用，其他反馈请发送ISSUE）
+
+NextTrace 有多个数据源可以选择，目前默认使用的 LeoMoeAPI 为我们项目维护的数据源。
+
+该项目由 OwO Network 的 [Missuo](https://github.com/missuo) && [Leo](https://github.com/sjlleo) 发起，由 [Zhshch](https://github.com/zhshch2002/) 完成最早期架构的编写和指导，后由 Leo 完成了大部分开发工作，现主要交由 [tsosunchia](https://github.com/tsosunchia) 以及 MoeQing Network 完成后续的二开和维护工作。
+
+LeoMoeAPI 是 [Leo](https://github.com/sjlleo) 的作品，归属于 Leo Network，由 [Leo](https://github.com/sjlleo) 完成整套后端 API 编写，该接口未经允许不可用于任何第三方用途。
+
+LeoMoeAPI 早期数据主要来自 IPInsight、IPInfo，随着项目发展，越来越多的志愿者参与进了这个项目。目前 LeoMoeAPI 有近一半的数据是社区提供的，而另外一半主要来自于包含 IPInfo、IPData、BigDataCloud、IPGeoLocation 在内的多个第三方数据。
+
+LeoMoeAPI 的骨干网数据有近 70% 是社区自发反馈又或者是项目组成员校准的，这给本项目的路由跟踪基础功能带来了一定的保证，但是全球骨干网的体量庞大，我们并无能力如 IPIP 等商业公司拥有海量监测节点，这使得 LeoMoeAPI 的数据精准度无法和形如 BestTrace（IPIP）相提并论。
+
+LeoMoeAPI 已经尽力校准了比较常见的骨干网路由，这部分在测试的时候经常会命中，但是如果遇到封闭型 ISP 的路由，大概率可以遇到错误，此类数据不仅是我们，哪怕 IPInsight、IPInfo 也无法正确定位，目前只有 IPIP 能够标记正确，如对此类数据的精确性有着非常高的要求，请务必使用 BestTrace 作为首选。
+
+我们不保证我们的数据一定会及时更新，也不保证数据的精确性，我们希望您在发现数据错误的时候可以前往 issue 页面提交错误报告，谢谢。
+
+当您使用 LeoMoeAPI 即视为您已经完全了解 NextTrace LeoMoeAPI 的数据精确性，并且同意如果您引用 LeoMoeAPI 其中的数据从而引发的一切问题，均由您自己承担。
+
+## DN42 模式使用说明
+
+使用这个模式需要您配置 2 个文件，分别是 geofeed.csv 以及 ptr.csv
+
+当您初次运行 DN42 模式，NT 会为您生成 nt_config.yaml 文件，您可以自定义 2 个文件的存放位置，默认应该存放在 NT 的运行目录下
+
+### GeoFeed
+
+对于 geofeed.csv 来说，格式如下：
+```
+IP_CDIR,LtdCode,ISO3166-2,CityName,ASN,IPWhois
+```
+
+比如，您可以这么写：
+
+```
+58.215.96.0/20,CN,CN-JS,Wuxi,23650,CHINANET-JS
+```
+
+如果您有一个大段作为骨干网使用，您也可以不写地理位置信息，如下：
+
+```
+202.97.0.0/16,,,4134,CHINANET-BACKBONE
+```
+
+### PTR
+
+对于 ptr.csv 来说，格式如下：
+```
+IATA_CODE,LtdCode,RegionName,CityName
+```
+
+比如对于美国洛杉矶，您可以这么写
+
+```
+LAX,US,California,Los Anegles
+```
