I spent a lot of time on that in an earlier email, one you chose to not respond to. There are two ways: (a) it reports the address it knows, and the DNS server infers the other addresses, or (b) it sends an ICMP request to a multicast address, collects zero or more responses, and reports what it collects. I personally prefer (a); we don't have to change your laptop. That said, I could use (b) to optimize; if I accept the first response that comes within a second or (if it is non-null) the set of responses that come within 100 ms (picking numbers out of the air, if you don't like them pick other numbers), and I have a network like Cisco's in which DMZs might be several hundred milliseconds apart, then I only select addresses that I would actually like a peer to use. _______________________________________________ nat66 mailing list [email protected] https://www.ietf.org/mailman/listinfo/nat66
