Not sure about that - e.g. this thread is not really conclusive regarding whether DNS lookup is done here or not: http://stackoverflow.com/questions/7388847/does-inetaddress-getlocalhost-gethostaddress-involve-dns-server

Do you have some proof that there is really a network connection, or is this just a guess? Thanks.
Comment 3 Marian Mirilovic 2012-04-16 13:04:15 UTC 
Increasing priority to P2 - after discussion with performance team and based on the goal for NB 7.2 (performance improvements) especially for remote filesystems.
Comment 4 Petr Jiricka 2012-04-16 13:42:17 UTC 
Probably not a bug per comment above, marking as incomplete until this is clarified.
