1461

IBM Wireless LAN

Registered as IBM Wireless LAN; a 1990s assignment with no current documentation.

TCP UDP IANA registry

Description

IANA registers 1461 on TCP and UDP as ibm-wrless-lan, "IBM Wireless LAN" (the well-formed name IANA issued to replace the older ibm_wrless_lan spelling). It dates from IBM's pre-802.11 wireless LAN products and there is no published protocol specification or supported implementation today. Nothing well-documented squats here, so an open 1461 should be traced to its process on the host rather than read off the registry.
