whois.networksolutions.com is just wrong -- it only returns information
for Network Solutions domains.
whois.opensrs.net is a bit better -- it returns information for OpenSRS
domains, and otherwise recurses to the correct whois server for other
domains -- unfortunately it is not canonical, and cannot be construed as
"correct." Other recursing proxies include whois.geektools.com and pallas.
eruditorum.org, neither of which is "official" either.
For good or for ill, we go back to whois.internic.net, which is the canonical
source for this information.
whois.opensrs.net, which does internal recursion for domain data.
Network Solutions' server recurses on only _some_ registries, and has the
damned disclaimer and advertising on no-match results.
the WHOIS service, again. New target: whois.networksolutions.com
This program should be replaced with one that does WHOIS++ so that it
can hit all the registries for data.
