what would you have f.root-servers.org do in that case?  our IPv4 address
is in a /24, and our IPv6 address is in a /48.  even apart from the question
of how long it takes to renumber a root name server, where would you like us
to move?  we have other address blocks but those other blocks aren't anycast.
