                              IN-ADDR.ARPA DNS

I've been helping someone setup DNS—more specifically, so he can control the
reverse lookups. I use NS records [1] but according to the documentation of
BIND [2] and RFC2317, [3] you're supposed to use this horrible CNAME hack.
The only thing I can think of for doing that, beyond the Complexity for
Complexity's Sake Syndrome, is to avoid confusing a person over having to
configure an IN-ADDR.ARPA domain they're not really delagated to serve.

I was told the trick by my friend Kelly [4] who used it for his home network.
He sat down and applied some thought as to how DNS works and came up with
this method.

I like it better than the “official” way.
