Bzzt. Thank you for playing, though. If it were not for WinS, there wouldn't be a second packet being sent, no matter what junk is the payload.

solid in-addr.arpa reverse mappings, this would go away. Microsoft's DNS resolver has been extended, when DNS lookups fail, to do a reverse NETBIOS query against the target machine so it can use its name when displaying stuff via NBTSTAT, etc. It was designed this way, before the Internet became popular.

Excuse me? I was using the Internet way before Microshaft was a dream in Bill's head. The RFC's you quote were rammed into existance by DARPA to provide early ecanpsulation techniques so that companies like MS could say they were IP/Internet compatible, (instead of using a real protocol) and get away from Novel slamming them for non-routable protocol support only. All they did was to take the same non-routable junk and throw it inside an ip packet and call it "internet" compatible. The RFC's quoted provide a way to make that encapsulation work, they do not recommend conversion to that as a standard. To encourage that kind of conversion would be a major leap backwards. (Wow! let's all abandon our routeable protocols and use a non-routed local segment only, encapsulated protocol. Yippee!) Now I agree ISP's should do better DNS resolution, but every MS box plugged into the net sending a second packet adds up to a lot of junk packets eating up expensive bandwidth. MS catches the blunt of the critisizm because they are the only ones to have adopted such a lame networking scheme, and then forced it down others quotes.

Before we all rant at MS, I suggest we all read RFC's 1001 and 1002 and UNDERSTAND NetBIOS over IP, before we blame ALL the worlds ills on MS. Last I knew, they weren't written by MS.
