All this is assuming that there is indeed anycasting involved, instead
of just "the webserver having a cool and easy-to-remember IPv6 address".

You can't see that from outside the network in question - and I'd put my
$5 into the "it's just a webserver, no anycast involved, and quite 
likely the address is bound as a /128 to its loopback, so there is not
even a subnet involved where this could be the router-anycast address".
