You can retrieve a list of GitHub's IP addresses from the meta API endpoint. For more information, see "Meta."
These ranges are in CIDR notation. You can use an online conversion tool such as this CIDR / VLSM Supernet Calculator to convert from CIDR notation to IP address ranges.
We make changes to our IP addresses from time to time, and will keep this API up to date. We do not recommend allowing by IP address, however if you use these IP ranges we strongly encourage regular monitoring of our API.
For applications to function, you must allow TCP ports 22, 80, 443, and 9418 via our IP ranges for github.com.

Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
