As pointed out by Rob Seastrom in private email, RFC2182 addresses things
of biblical proportions - such as dispersion of nameservers geographically
and topologically. Having 3 secondaries, only one of them on separate /24,
and none of them on topologically different network does not qualify.

ns1.register.com.       600     IN      A       216.21.234.96
ns2.register.com.       600     IN      A       216.21.226.96
ns3.register.com.       600     IN      A       216.21.234.97
ns4.register.com.       600     IN      A       216.21.226.97

This is two pairs, each pair in a single /24 (or /26), and there are
ways in which each of these hosts could be in a widely different spot
from the other three, or in several different spots.

Why am I saying this?  Most of the folks here know this and how to do
this even better than I do.

I am not saying that register.com IS doing this, just that you can't say
that they're NOT just from this evidence.

And by now it's moot anyway.
