Even under the most wildly optimistic scenarios, it's hard to imagine
new TLDs being added more than once a month, and I presume that
everyone here already knows how easy it is to get copies of the root
zone. The reasonable way to validate TLDs is to fetch a copy of the
zone every couple of weeks and cache it.
By the way, to be sure we're all on roughly the same page, here's a
quiz. How many names are there in the root zone right now?
a) 11
b) 97
c) 153
d) 280
e) 974
