ResolveIPAddresses now returns an error wrapping ErrNoNameserverAnswered when every nameserver of the name's zone timed out or failed, instead of no addresses and no error. It reads each nameserver's status as the lookup already sets it; one answer, even NXDOMAIN, is enough for an empty result without an error. The only caller, the nameserver address lookup, already keeps the previous addresses on an error; its comment no longer says the resolver hides this case. Model: opus-5-5
