[REBOL] ping Re:

[lnusrn1 . bz3r4j]

I was wondering the same thing about a simple ping.

What is the RFC that describes? Can't find it. Query tool of RFC's kept telling
me
about ship"ping"  and stop"ping" and stam"ping". .. but not whole world "ping".

ping seems like with would be very simple... but is there an RFC that describes
the true "ping" requirements??
