“Evaluating The Effects Of Anycast On DNS Root Nameservers”: ripe.net/publications/docs/rip

some interesting statistics for (among other things) reliability of stateful (TCP) connections on anycast nodes, specifically in the context of DNS.

it is from 2006, so i wonder how numbers have changed in the mean time.

RIPE Network Coordination CenterEvaluating The Effects Of Anycast On DNS Root Nameserversripe-393: The DNS root nameservers are a critical part of the Internet’s infrastructure, and anycasting is increasingly being used in their deployment.

The #openbsd 7.7 release openbsd.org/77.html is so close it's too late to upgrade from a shapshot to the release, but you can prepare by reading "You Have Installed OpenBSD. Now For The Daily Tasks." nxdomain.no/~peter/openbsd_ins, and watching for updates over on the OpenBSD Journal undeadly.org

Things I learnt about DNS:

1. You can't "redirect" an entire domain with CNAME, only subdomains, which is why my website has been broken.

2. You can't specify an AAAA record and use a wildcard for the A record. You have to explicitly put both.

If the IP changes, you have to change it everywhere. I wonder if there is a modern DNS server which lets you avoid this sort of data duplication.
