As a result, subsequent Netplan config applications fail because DNS servers don’t have the expected dotted decimal (IPv4) or colon’ed hex (IPv6) form. ``` nmcli> describe ipv4.dns === [dns] === [NM property description] Array of IP addresses of DNS servers. For DoT (DNS over TLS), the SNI server name can be specified by appending "#example.com" to the IP address of the DNS server. This currently only has effect when using systemd-resolved. ``` To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/2055148/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
