It's the server TO WHICH YOUR MACHINE IS CHATTING. However, *YOUR* machine is identifying itself to the yahpoo server as "?192.168.1.3?" That is what is invalid for 2 reasons: a) it's meant to be an address literal, so it should be a public address, not an address in RFC1918 space. b) The address should be between [square brackets], not question marks. - -- G.
