Maybe this will give you some ideas:
# perl -le'$host = "google.com"; ($ip) = `nslookup $host` =~
/Name:\s+$host\s+Address(?:es)?:\s+(.+)/; print $ip'
216.239.33.100, 216.239.35.100, 216.239.37.100, 216.239.39.100
# perl -le'$host = "groups.google.com"; ($ip) = `nslookup $host` =~
/Name:\s+$host\s+Address(?:es)?:\s+(.+)/; print $ip'
216.239.35.119
