Dig, the domain information grouper, is a tool that sends DNS queries to servers and prints the replies. I think most network engineers find it more useful than nslookup, which has now be depricated by ISC, anyway.
The Web form below uses a Perl script to make DNS queries. It's output is similar to Dig, but not identical, since it's purely Perl-based, so that it works on Windows systems that don't have Dig. If it doesn't work, try the original version at freesoft.org. Dig is available as part of the Bind distribution.
$ dig @localhost www.freesoft.org A IN
;; query(www.freesoft.org, A, IN) ;; setting up AF_INET6 UDP socket with srcaddr [::] ... done ;; setting up AF_INET UDP socket with srcaddr [0.0.0.0] ... done ;; no nameservers ;; query status: no nameservers
