The upstream issue actually applies to both. IMHO, if you restrict a DNS server to a particular list of domains it should be used *exactly* for the given domains (only). Querying it for other domains is a privacy leak, and querying other name servers for those domains is most probably going to fail anyway and thus a waste.
> Also, here I am using NetworkManager, not systemd-networkd. That's unrelated, as that is about resolving DNS names, not bringing up the network. So, this does match the upstream issue, setting to triaged. ** Changed in: systemd (Ubuntu) Status: New => Triaged ** Changed in: systemd (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1624317 Title: systemd-resolved breaks VPN with split-horizon DNS To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1624317/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
