This doesn't even require SRV records; there are many DNS names that
resolve into multiple IPs through the definition of multiple A/AAAA
records for that name. In that case, though, the receiver of that list
of IPs has no priority/weighting information to rely upon, so it should
just choose the first IP in the response (and implicitly rely on random
ordering provided by the DNS query/resolution process itself).
