It's Ubuntu 13.04's 5.0.20ubuntu1 client, so it really shouldn't be much
different from the Debian whois you're using.

Also, whois -h networksolutions.com works just fine (and
includes the blurb).

Doing this results in it just hanging, similar to with the whois client:

sfrost at tamriel:/home/sfrost> telnet 2001:503:5ae2:1060::74 43
Trying 2001:503:5ae2:1060::74...
Connected to 2001:503:5ae2:1060::74.
Escape character is '^]'.

Whois Server Version 2.0

Domain names in the .com and .net domains can now be registered
with many different competing registrars. Go to http://www.internic.net
for detailed information.

[... hanging here, still ...]

Ah, yea, good point. :)

It usually tells you that, actually, and so I doubt that's the case.
Also, attempting from other IPv6 addresses results in the same hang
(even with the telnet approach).
