[Bug 1682386] Re: systemd-resolved can not resolve .coop domain names

[Jeffrey Blanchard]

I just updated to Zesty 17.04 and I am having trouble accessing .coop
sites using Chromium and Firefox.

This site can’t be reached
www.gaiahost.coop’s server DNS address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN

I also use a .coop domain for my email server and can't access that
either.

Everything still works fine on my other computer running 16.10

Title:
  systemd-resolved can not resolve .coop domain names

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  I am using Ubuntu Gnome 17.04, systemd version 232-21ubuntu2.

  I found that .coop domain nomes are not being resolved. If I switch to
  another DNS server (instead of 127.0.0.53, which is the current
  default in 17.04), then .coop domains are resolved:

  $ nslookup
  > www.somenergia.coop
  Server:		127.0.0.53
  Address:	127.0.0.53#53

  ** server can't find www.somenergia.coop: SERVFAIL
  > server 8.8.8.8
  Default server: 8.8.8.8
  Address: 8.8.8.8#53
  > www.somenergia.coop
  Server:		8.8.8.8
  Address:	8.8.8.8#53

  Non-authoritative answer:
  Name:	www.somenergia.coop
  Address: 164.132.200.9
