MapLocalDns ( string name ) : bool	Sets up DNS for localhost
NameLookUp ( String ip ) : String	This method does an inverse lookup for the DNS
RemoveDnsMapping ( string alias, bool reverse ) : void	Remove Dns alias mapping.
RemoveIPMapping ( string ip ) : void	Remove IP to Brunet address mapping.
Resolve ( MemBlock IP ) : Brunet.Address	Returns the Brunet address given an IP
Translate ( MemBlock packet, Brunet.Address from ) : MemBlock	Implements the ITranslator portion for ManagedAddress..., takes an IP Packet, based upon who the originating Brunet Sender was, changes who the packet was sent from and then switches the destination address to the local nodes address. Takes incomming packets only.
