Actually I need to get the root domain from the URL as a previous step to a
WHOIS query. You can't do a WHOIS on "www.example.com". It has to be
"example.com" only.
dig www.example.com doesn't always give the information I need either.
I think DNS is the way to go, but need to figure out why dns_get_record()
returns an empty "authns" array for some of us but works properly for Robin
and for the example in the manual. I haven't found anything yet, but I'll
keep searching.
Thanks,
Brad
