-# NextTrace
+## NextTrace
 
-一款开源的可视化路由跟踪工具，使用Golang开发。
+An open source visual routing tool that pursues light weight, developed using Golang.
+
+NextTrace is part of the [OwO Network](https://github.com/OwO-Network) project. The project is a joint initiative of Leo and Vincent.
 
 ## How To Use
 
-### Install
+Document Language: English | [简体中文](README_zh_CN.md)
+
+### Automated Installation
 
 ```bash
-bash -c "$(curl -Ls https://raw.githubusercontent.com/xgadget-lab/nexttrace/main/nt_install.sh)"
+# Linux one-click install script
+bash <(curl -Ls https://raw.githubusercontent.com/sjlleo/nexttrace/main/nt_install.sh)
+
+# macOS brew install command
+brew tap xgadget-lab/nexttrace && brew install nexttrace
+
+# GHProxy Mirror (For China Mainland User)
+bash -c "$(curl -Ls https://ghproxy.com/https://raw.githubusercontent.com/sjlleo/nexttrace/main/nt_install.sh)"
 ```
 
+Windows users please go to [Release Page](https://github.com/sjlleo/nexttrace/releases/latest) directly and download exe file.
+
+- `Release` provides compiled executables for many systems and architectures, if not, you can compile it yourself.
+- Some of the necessary dependencies of this project are not fully implemented in `Golang` on `Windows`, so currently `NextTrace` is experimental on `Windows` platform.
+
 ### 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
 
-# 获得 route-path
-nexttrace -report 1.0.0.1
-
-# 打开IP反向解析 rdns
-nexttrace -rdns 1.0.0.1
-
-# 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 (output all hops at one time, wait 20-40 seconds)
+nexttrace --table 1.0.0.1
 
 # 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`也可以使用`TCP`和`UDP`协议发起`Traceroute`请求，不过目前只支持`IPv4`
+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
+# IPv4 ICMP Fast Test (Beijing + Shanghai + Guangzhou + Hangzhou) in China Telecom / Unicom / Mobile / Education Network
+nexttrace --fast-trace
+
+# You can also use TCP SYN for testing
+nexttrace --fast-trace --tcp
+```
+
+`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
 ```
 
-### IP数据库
+`NextTrace` also supports some advanced functions, such as ttl control, concurrent probe packet count control, mode switching, etc.
 
-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。
+```bash
+# Send 2 probe packets per hop
+nexttrace --queries 2 www.hkix.net
 
-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。
+# No concurrent probe packets, only one probe packet is sent at a time
+nexttrace --parallel-requests 1 www.hkix.net
 
-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/)
+# Start Trace with TTL of 5, end at TTL of 10
+nexttrace --first 5 --max-hops 10 www.decix.net
 
-### 全部用法详见Usage菜单
+# Turn off the IP reverse parsing function
+nexttrace --no-rdns www.bbix.net
+
+# Feature: print Route-Path diagram
+# Route-Path diagram example:
+# AS6453 Tata Communication「Singapore『Singapore』」
+#  ╭╯
+#  ╰AS9299 Philippine Long Distance Telephone Co.「Philippines『Metro Manila』」
+#  ╭╯

+#  ╭╯
+#  ╰AS37963 Aliyun「ALIDNS.COM『ALIDNS.COM』」
+nexttrace --route-path www.time.com.my
+```
+
+`NextTrace` supports users to select their own IP API (currently supports: `LeoMoeAPI`, `IP.SB`, `IPInfo`, `IPInsight`, `IPAPI.com`, `Ip2region`, `IPInfoLocal`, `CHUNZHEN`)
+
+```bash
+# 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` supports mixed parameters and shortened parameters
+
+```bash
+Example:
+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 Database
+
+#### We use [bgp.tools](https://bgp.tools) as a data provider for routing tables.
+

+`NextTrace Enhanced` is an enhanced version for enthusiasts, `Enhanced` provides trace route calls in the form of Web API and a simple Looking Glass webpage with built-in visualization.
+
+Please Notice that `NextTrace Enhanced` is currently not supported in English.
+
+https://github.com/OwO-Network/nexttrace-enhanced
+
+## 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 on 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.

+
+## How To Use
+
+### Before Using
+
+使用 NextTrace 之前，我们建议您先阅读 [#IP 数据以及精准度说明](https://github.com/sjlleo/nexttrace/blob/main/README_zh_CN.md#ip-%E6%95%B0%E6%8D%AE%E4%BB%A5%E5%8F%8A%E7%B2%BE%E5%87%86%E5%BA%A6%E8%AF%B4%E6%98%8E)，在了解您自己的对数据精准度需求以后再进行抉择。
+
+### Automated Install
+
+```bash
+# Linux 一键安装脚本
+bash <(curl -Ls https://raw.githubusercontent.com/sjlleo/nexttrace/main/nt_install.sh)
+
+# GHPROXY 镜像（国内使用）
+bash <(curl -Ls https://ghproxy.com/https://raw.githubusercontent.com/sjlleo/nexttrace/main/nt_install.sh)
+
+# macOS brew 安装命令
+brew tap xgadget-lab/nexttrace && brew install nexttrace
+```
+
+Windows 用户请直接前往 [Release](https://github.com/sjlleo/nexttrace/releases/latest) 下载编译后的二进制 exe 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。
+
+### 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
+
+# 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
+
+# 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
+```

+
+## Others
+
+其他第三方 API 尽管集成在本项目内，但是具体的 TOS 以及 AUP，请详见第三方 API 官网。如遇到 IP 数据错误，也请直接联系他们纠错。
+
+## IP 数据以及精准度说明
+
+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。
+
+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
+```
+
+需要注意的是，NextTrace 支持自动匹配 CSV 中的城市名，如果您的 PTR 记录中有 `losangeles`，您可以只添加上面一条记录就可以正常识别并读取。
