* 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. |
