bgp.tools December 2025 Changelog

It has been a while since the last changelog update, and a lot of stuff has been happening behind the scenes to make the system a more stable and sustainable for long term growth.

Let’s go over some of those changes!

ASPA Alerting Support

RIPE recently unveiled support for setting ASPA objects in their RPKI Dashboard, while bgp.tools has has support for ASPA for a while, it has not had the ability to alert on violations and when objects were made, this is what this new feature aims to improve upon!

The first new alert focuses on when your network is involved (either as a victim or as a perpetrator) in a ASPA violation

The second set of alerts are notifications for when ASPA changes involving you are made

IX address searches now jump to the peer

When searching for a Internet Exchange peer address, bgp.tools will now auto-scroll to the member it belongs to with a highlight (if the member was found)

This means you can easily copy and paste a next hop address from a router CLI output directly into the search box and get the more reasonable result (for the case of internet exchange next hops)

Better Up/Downstream flap detection

Sometimes route leaks are very quick (on the orders of seconds in terms of visibility), previously when these kinds of leaks happened bgp.tools would send a “Lost Upstream” alert without much context on what had happened, this has now been fixed and a dedicated alert will be sent for this situation with much better detail (including the prefix and example routes) for fault finding/root cause analysis.

New IXPs

bgp.tools is now accepting feed sessions on the following exchanges:

  • FD-IX - Indianapolis
  • COIX
  • LINX LON2
  • QLD-IX
  • ACT-IX
  • WA-IX
  • SA-IX
  • NSW-IX
  • VIC-IX
  • TOPIX

bgp.tools has left:

  • ONIX
  • Douala-IX

This brings bgp.tools AS212232 to 122 internet exchanges!
