Wonderful.. so now we have to do routing in DNS, a protocol that's not 
exactly designed for rapid convergence (yes, neither is BGP, but it's a 
*lot* faster then DNS). Just brilliant.

While the status quo is not sustainable if growth continues for 4+ years, 
deciding to "fix" the problem by pretending that there was never a 
good reason for it in the first place, and moving it to a different place 
is not a very good architectural solution either.

And I hope this thread points out why more content isn't v6 enabled.. And 
no, I'm not saying that "the evil greedy bastards" did this on purpose, 
unfortunately, it's simply yet another example of things being created 
without operator involvement (and yes, we, the operators, are at fault for 
that). See you on shim6 at .
