Public bug reported: I'm using Ubuntu 16.04 on a network where the DNS server is available on both IPv4 and IPv6 (managed by a router running OpenWrt). As mentioned in the dnsmasq manpage, I can see dnsmasq has both IPv4 and IPv6 entries by running:
dig +short chaos txt servers.bind I also have an IPv4-only OpenVPN connection configured through NetworkManager (the VPN itself is IPv4-only, the NM connection is set to Automatic for both IPv4 and IPv6), with no split-tunnelling. When I connect to the VPN and query dnsmasq again, I see that the IPv4 entry has been replaced by the VPN IPv4 DNS server, but the (local network) IPv6 entry is still present. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1615343 Title: IPv6 DNS server not removed when connected to IPv4-only OpenVPN VPN Status in network-manager package in Ubuntu: New Bug description: I'm using Ubuntu 16.04 on a network where the DNS server is available on both IPv4 and IPv6 (managed by a router running OpenWrt).
