I'm not really sure WHY you would want that info. It's all assigned via 
DHCP and could change at a given moment. It's possible in the future your 
IP could be a on a completely different subnet, making the gateway address 
you were using before unreachable.

DNS servers too are assigned via DHCP so there is no need to manually 
enter them.
