No, it's not. For it to be an FQDN you need to add a . (dot) at the end
of ubuntu.gateway.2wire.net; i.e., ubuntu.gateway.2wire.net(.)

http://en.wikipedia.org/wiki/FQDN

That said, if you want an actual DDNS that you can use as a proper FQDN
for internet activity then go and get a free DDNS:
http://www.dyndns.com/services/dns/dyndns/
Something like chatagnier.dynalias.org or .homeunix.org etc:

You'll need to run a DDNS client to keep it updated (my router does it
for me so I've not tested any of these):
