Thanks for all your help guys. I really want to understand why these work though, so could someone explain the '{close(out);out=$(NF-2);print $(NF-3)>>out}' part if its not too much of a hassle?

So gawk -F is using "=" as a delimiter and then splitting up the output that way? then I assume the parts are assigned to $# variables then the $(NF-2 or 3) is getting the 'hostname' and 'domain' parts?
-F '[ =.]' makes space/=/. as field separators.
NF - NumberofFields

12.12.52.125.in-addr.arpa name = hostname.domain.main.gov

'gov' - last field (NF)
'main' - next to last field (NF-1)
'domain' - 2nd to last field (NF-2)
'hostname' - 3rd to last field (NF-3)

Code:
echo "12.12.52.125.in-addr.arpa            name = hostname.domain.main.gov" | sed 's/.* = //'

Code:
$ a="12.12.52.125.in-addr.arpa               name = hostname.domain.main.gov"
$ echo "${a##* = }"
hostname.domain.main.gov
