If you choose to only get the IP address from DHCP and you don't specify and DNS servers to use, then there won't be any DNS servers configured (besides 127.0.1.1).
What will happen is that a DNS request will be sent to 127.0.1.1 (dnsmasq). dnsmasq doesn't have any upstream servers configured, so unless the IP address for the domain is statically set somewhere in the configuration file, DNS won't work. -- 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/1577724 Title: NM doesn't sets the DNS properly, forces local dnsmasq as a resolver Status in network-manager package in Ubuntu: Incomplete Bug description: 1. Setup a network with DHCP address, gateway and DNS. 2. Connect to that network. 3. Check the resolver configured in /etc/resolv.conf Expected result: To find "nameserver" set to the DNS addresses provided by the external DHCP server Actual result: "nameserver=127.0.1.1" in any case.
