A. (off-topic) host gives better output than nslookup.
B. This works, and technically it's a shell command.
$ perl -e 'print join";",map"host 207.189.128.$_",1..254' | sh
(Substitute nslookup for host if you prefer.)
C. Here it is with no Perl.
$ i=1
$ while [ $i -le 254 ]

D. (off-topic) That's a pretty eclectic netblock, once you get past
willamette.net's servers. Isn't Eugene wonderful?
