Hmm. It's the same principle, but the details are different. At
Genuity, this would presumably be realised using OSPF or IFRP. For
the root and TLD name servers, anycasting is based on BGP.

Oh, yeah. Especially when the IP address of those servers have to be
embedded into zillions of desktops that are unlikely to ever get
reconfigured.
