I get the following:- ngoonee@ngoonee-laptop ~ % wget -O - icanhazip.com --2011-06-06 14:21:38-- http://icanhazip.com/ Resolving icanhazip.com... 50.56.84.181, 2001:470:1f10:d57:feed:beef:cafe:d00d Connecting to icanhazip.com|50.56.84.181|:80... connected.

Not surprising. Wonder whether its worth even letting them know. Could it perhaps be something set wrongly in my router? ping6 just hangs....
