ipverse-announced-routes

A collection of IPv4 and IPv6 routes grouped by the announcing autonomous systems. The routes are aggregated to save space.
This repository is updated daily.

Potential Use cases

• Firewalling, e.g. to ban all IP addresses from that annoying, Spam-friendly network provider
• Route advertisment check, see if/how the routes of a specific autonomous system are seen (even over time, thanks to git's changelog)
• Statistical analysis purposes, e.g. the number of public IPv4 addresses currently announced vs unused/unassigned
• Find out more about a specific ASN using the provided lookup table (currently .csv format only) or use it in your own software project for offline use

How to use

Most likely, you won't need to clone the repository. To download the announced routes for a specific autonomous system (AS1234 IPv4 adresses in this example), try:
$ curl https://raw.githubusercontent.com/ipverse/announced-routes/master/as/1234/ipv4-aggregated.txt

The same for all IPv6 routes for AS1234:
$ curl https://raw.githubusercontent.com/ipverse/announced-routes/master/as/1234/ipv6-aggregated.txt

To download the latest lookup table used to enhance the generated route data:
$ curl https://raw.githubusercontent.com/ipverse/announced-routes/master/as.csv

If you plan to use the routing data for firewalling purposes, have a look at:
