You might be running into this:

As far as I can tell, DNS won't work unless your DNS server supports 
IPv6 (AAAA) queries.  If this sounds like your problem, I'd appreciate 
the input.  The glibc devs have been ignoring this.

I'm not sure if dig can tell you what you need to know here.  You could 
try "dig -t aaaa google.com" and see what you get.  Otherwise, try to 
use "tcpdump -w /var/tmp/dns.dump -s0 port 53" to capture the DNS lookup 
that happens when you try to connect with telnet.  Use Ctrl+C to stop 
capturing, and then send /var/tmp/dns.dump back to the list.
