Title:
  IPv4 DNS preferred over IPv6 ones

Status in NetworkManager:
  Unknown
Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  The Network Manager always prefers IPv4 DNS over IPv6 ones. The issue
  occurs both when DNSs are statically configured and when they're
  acquired via DHCPv4/DHCPv6.

  Network Manager puts IPv4 DNSs before IPv6 ones in the /var/run/nm-
  dns-dnsmasq.conf so Dnsmasq resolves names using IPv4 DNSs before
  using IPv6 ones.

  If I disable Dnsmasq, DNS servers are put in the wrong way in
  /etc/resolv.conf file.

  The system shoud prefer IPv6 DNSs in any case.
