Hi, Ron,

Anytime!

“Extended Ping” is the name for the interactive version of the ping utility. A search engine seems to find a bunch of others (it is a natural extension for a name :-)

This particular utility seems to have less commonality to `ping` than to an atomic query for remote operational state. For example, in a topology like A-----IPv4_only_net-----B, where B has an IPv6 interface. If xping is sent as an ICMPv4, querying for an IPv6 interface, will it return “Up” even though there is no IP connectivity to that interface?

If so, that’s less a probe and more a get_interface_state.

That could otherwise be two different reports, one for path connectivity and the other for interface state, without agglutinating them or mixing AFs.

I must say though that I actually really like the salutation-themed naming. Konnichiwa is perhaps too long… Yo? Hey? Too informal… :-) It is a sort-of AYU (Are You Up?)

— Carlos.
