AFAIK, nic.ar never had a whois service... only queries via web... in
fact, at one point, the output of the web query was a .gif
autogenerated...
I think it's now again plain text, so you should be able to
automatically query it using LWP or something along the lines (it only
accepts POSTs not GETs).
