[mod.protocols.tcp-ip] Port collisions: use domains!

JJW@SU-AI.ARPA.UUCP (05/17/86)

Why not add service-name to port-number mapping to the information stored
in domain nameserver databases?  For example, if we decide to implement
the Whizbang protocol on port 1234, then our nameserver would contain a
resource record of the form

    Whizbang.SAIL.Stanford.EDU  IN  TCP-PORT  1234

Applications would refer to the protocol by name, and find the port number
using a domain resolver, which will cache the information for next time.
The "well-known" protocols would bypass this mechanism since their port
numbers are known.
