But that will list everyone who's _currently_ active; it won't list
everyone who _ought to be_ active. However, the OP was slightly
ambiguous:

Does "ping a nearby host" simply mean that you want to ping someone
who's up, as a means of testing the client's own network connection?
Or are you seeking to list all servers and know if any has gone down?

If the former, it's quite easy. In fact, you could just hard-code a
few IPs of key routers and/or servers, and ping those, much more
easily than listing hosts.
