ip-scanner

This script is used to find the fastest IP for a given domain name.

Use

• GoogleTranslate

  Google has ended its Google Translate service in mainland China. In order to continue using Google's translation service, look for available IPs.

• Cloudflare

  To better use Cloudflare pages and Cloudflare workers, find the fastest IP.

Quick start

Google Translate

Find available IPs for Google Translate:

go run cmd/google_translate/main.go

go run cmd/google_translate/main.go -config ./configs/config.toml

Fetch the latest IP ranges of Google Translate, save to the IPRangesFile path in the configuration file:

go run cmd/fetch_ip_ranges/main.go -site GoogleTranslate

Cloudflare

Find the fastest IP for Cloudflare:

go run cmd/cloudflare/main.go

go run cmd/cloudflare/main.go -config ./configs/config.toml

Fetch the latest IP ranges of Cloudflare, save to the IPRangesFile path in the configuration file:

go run cmd/fetch_ip_ranges/main.go -site Cloudflare

Custom site

Find available IPs for other websites, add configuration and run:

go run cmd/ip_scanner/main.go -site <site name>

Options:

-config string
    Config file, toml format (default "./configs/config.toml")
-site string
    site: the site name configured in the configuration file
