The process is usually: 1. The resolver will attempt to find an IPv6 AAAA address for the name. 2. If an IPv6 address is returned, see is there a route to it. 3. Attempt to connect over IPv6. If any of the above fail, do the same for IPv4. So a DNS query for AAAA records is pretty normal. If you don't have IPv6 set up, step 2 will fail, even where a AAAA address is returned. > /etc/hosts looks like > > 127.0.0.1 localhost > 127.0.1.1 vbuntu vbuntu.vanguard.vashonsd.org > 10.114.5.50 paul.vanguard.vashonsd.org paul > > my /etc/nsswitch.conf file has this entry > > hosts files dns wins So when /etc/hosts is checked for a AAAA record, that fails and a DNS request is made. > What exactly is going on here?
