HTTP80HyperText Transfer Protocol * (e.g. for web browsing). Currently (2003-07-05) HTTP/1.1 is officially described in RFC 2616.
HOSTS2 Name Server8181* An interesting story. The name attached to this port in the IANA list, Earl Killian, says he shouldn’t be. He says “I don’t know what 81 is, or whether it is still in use.” Since Mr. Killian doesn’t know what HOSTS2 is/was, and with Postel gone, I wonder if there’s anyone left in the world who knows what 81 was/is for and who actually requested it.
XFER Utility8282* Another interesting story. The name attached to this port in the IANA list, Thomas M. Smith of Lockheed Martin, says Sorry… there is no publicly available information regarding the details of the XFER Utility and its use of tcp and udp port # 82. XFER employs a proprietary protocol which has not been disclosed.
