In Randy's presentation there is the suggestion to develop an IX filter list. Nearly 20 years later that actually happened. <https://www.team-cymru.com/ixp.html> This wasn't a popular service when I left Team Cymru, but it seems to still be available if anyone wants to consider using that. For more on the historical record, about 10 years after Randy, and from my own experience, this was briefly touched on this in a lightning talk at NANOG 41, "Explorations in the Public Peering Address Space". As part of a project looking at peering discovery, in the Q&A Louie Lee as I recall provided a partial answer to the announcement question raised. It might be worth watching the video for those interesting in this. Scroll to the bottom to see the deck and video here: <https://www.nanog.org/meetings/nanog41/agenda> John

You could do the same trick. But with data fetched from PeeringDB via the public API. Works well. -Christoffer

Small note: I strongly recommend to *only* block IXP peering lan prefixes for IXPs you are actually connected to yourself. This way the communication lines are short in case there should be an exception. Don’t block prefixes unrelated to your operation. Kind regards, Job

There is also a feature request [0] to tag those prefixes whether they should be blocked or not. Once implemented it should be easy to build a filter. Arnold [0] https://github.com/peeringdb/peeringdb/issues/352 -- Arnold Nipper email: arnold@nipper.de mobile: +49 172 2650958
