I ran tcpdump 'host ubuntu20 and port domain' on my router and looked at all the other NXDOMAIN at boot time besides this one.

1. PTR request on the IPv4 address of my virbr0 interface. Gone after uninstalling a couple libvirt-* packages

2. PTR request on ONE of my IPv6 addresses. It's not obvious to me which address gets picked for that PTR query. I disabled IPv6 ULA on my router and the PTR request just moved to a different address.

3. SOA local. ??

I also found that NetworkManager needs to be told "connectivity-check.ubuntu.com has no AAAA record" about 12 times during boot, that seems a bit excessive? (this is not NXDOMAIN)
