[erlang-patches] [erlang-questions] Messenger example

[Per Hedeland]

You already got the answer to your question, but I would say that the
author of that "Note" is the one that is seriously confused. There is no
such thing as an "IP domain", and you most certainly can't give "the
first component of the IP address" as argument to -sname. Suggested fix:

Note: erl -sname assumes that all nodes are in the same DNS domain, and
thus that we can use only the first component of the host name. If we
want to use nodes in different DNS domains we must use -name instead,
but then all host names must be fully qualified.

Possibly it should mention the (AFAIK) otherwise undocumented fact that
you can use an IP address as 'Host' in '-name Name@REDACTED'.
