# 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 (autonomous system number) using the provided lookup table (currently .csv format only) or use it in your own software project for bulk/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:
|
|
|
|
- [ipset-blacklistlist](https://github.com/trick77/ipset-blacklist) ipset/iptables based Bash script, IPv4 only
|
|
- [todo](https://localhost) insert link to a popular project with nftables and IPv6 support
