[Glass] DNS problematic

[Dale Henrichs]

Dario,

At the moment there is no way to set a timeout on the 
`getHostAddressByName:` call, but we may add that feature in a future 
release so keeps your eyes peeled. It might be possible to change the 
time out by modifying /etc/resolv.conf.

If the result begins with '::ffff:' then you should be able to just 
remove that prefix from the result and have an IPv4 address.

Dale
