2023-10-30net/dns/recursive: update IP for b.root-servers.netAndrew Dunham1-2/+2
As of 2023-11-27, the official IP addresses for b.root-servers.net will change to a new set, with the older IP addresses supported for at least a year after that date. These IPs are already active and returning results, so update these in our recursive DNS resolver package so as to be ready for the switchover.

2023-07-06tstest: prepare for Clock API changesAdrian Dewhurst1-2/+2
This change introduces tstime.NewClock and tstime.ClockOpts as a new way to construct tstime.Clock. This is a subset of #8464 as a stepping stone so that we can update our internal code to use the new API before making the second round of changes.

2023-06-09net/dns/recursive: add initial implementation of recursive DNS resolverAndrew Dunham2-0/+1381
We've talked in the past about reworking how bootstrap DNS works to instead do recursive DNS resolution from the root; this would better support on-prem customers and Headscale users where the DERP servers don't currently resolve their DNS server. This package is an initial implementation of recursive resolution for A and AAAA records.
