It could do, but only on the wires local to the server. it would
still need to use ping for networks reached via routers. Hence two
lots of code.
But, remember that this is a "last chance" check to pick up
situations which are not supposed to happen. It's not required
(AFAIK) by any RFC, and I don't think it's done by other servers.
If there is a clash, the client is supposed to detect that locally
(?) and decline the lease offer.
