[SATLUG] Linux Client DNS Hostname Lookup Problem (reverse dns)

Good try but resolv.conf looks good... however the network admin thinks 
the problem is my laptop has ip6 protocols rather than ip4, which is 
what the windows-based DNS is on. Does that sound about right?  If it 
does, are there any commands I could run to add support fairly easily?

In Ubuntu, my Network Settings, Tab Hosts, had these entries for ip6 
(and none for ip4)
::1   ip6-localhost ip6-loopback
fe00::0  ip6-localnet
ff02::0  ip6-mcastprefix
ff02::1  ip6-allnodes
ff02::2   ip6-allrouters
ff02::3  ip6-allhosts
