Title:
Host name not resolved
Status in systemd package in Ubuntu:
Expired
Bug description:
Systemd-resolved fails to resolve a host which has a private IP address, even
though its DNS entry is public. This happens even when I am connected to a VPN
where the host resides.
Interestingly, if I manually issue a `host -a` request, the host gets
resolved, and further resolution works until its cached entry times out.
Here's some hopefully helpful output of me running `nslookup` and
`host`:
# nslookup
> presto.lmta.lt
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
*** Can't find presto.lmta.lt: No answer

[no output at all. I immediately run the next command]
# host -a presto.lmta.lt
