if it were externally visible (a separate /24 per site, say), there's
lots of good information over at www.nanog.org from various people
anycasting dns over the years. there's nothing special about tinydns
in this respect.
What i'm interested in is the marriage between the operation of the dns
daemon and the bgp injection. In this respect, the solution will be
special, at least in a DNS respect. I'm interested to see how people
are injecting the /32 when everything is working fine, and have the /32
go away when something breaks (such as the resolver not resolving a
known host).
in particular, verisign did a very nice presentation on this topic at
nanog39 in toronto:
http://www.nanog.org/mtg-0702/larson.html
there are lots of gotchas for that, but mostly related to long-lived
sessions and not having a covering route.
Thanks! I'm taking a peek now.
