Go CLI and Library for quickly mapping organization network ranges using ASN information.

Web-based CIDR / netmask / IP address visualizer

Simple, effective, and modular package for parsing observables (indicators of compromise (IOCs), network data, and other, security related information) from text. It uses grammars rather than regexes which makes it more readable, maintainable, and hackable. Explore our interactive documentation here: https://hightower.space/ioc-finder/

🔨 List IP ranges of: Google, Bing, Amazon and Cloudfront, Microsoft, Azure, Oracle, DigitalOcean, GitHub, Facebook, Twitter, Linode, Yandex, Vkontakte, Telegram, Netflix, Valve, Spotify, ChatGPT, YouTube with regular auto-updates for Shadowsocks (user rules) in ACL (Access Control List) format.

Convert IP address range to CIDR

This Python script is designed to retrieve a list of CIDR ranges from a given ASN (Autonomous System Number). The script makes an HTTP request to an IP address service, extracts the CIDR ranges, and saves the results to a file. It also supports data caching to speed up subsequent requests.

With this tool you can spot the CDN IPs and exclude them from your target list.

De-aggregates an IP address range into a list of network prefixes (CIDR blocks)
