It's a good idea, but of course that requires someone in the allocated
block to have a list of addresses to ping, all over the net.
Furthermore, the pinging really should be done from an actual use of
the net, and not just from, say, the RIR that allocated the block.
(Pinging a single address in new blocks would have that requirement,
too, of course.)
