Comment Routing tables? (Score 1) 23
I have been playing with routing tables. I have a few virtual machines around the globe that have full BGP routing tables and that gives me great IP -> ASN details. That means someone comes into a server and that might get redirected to as1221.my2026.example.com but that is a virtual web server with a few hundred thousands others. Everything nice and fast until there is a problem. Once that hits, that ASN gets redirected to the slow scrape box.
Also there is ipasn.net created at APNic. host -t txt 8.8.8.8.ipasn.net gives ownership of the block and other details involving things like its Route PKI status. It is part of their lab so I'm not sure how much traffic it can cope with.
