Hi, I am facing issue stoping NetworkManager to update resolv.cfg, I am using below configuration for eth0 interface: TYPE=Ethernet BOOTPROTO=dhcp DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=eth0 UUID=93b90a46-dab5-4a67-8fd0-fefe8874a8b9 DEVICE=eth0 ONBOOT=no PEERDNS=no PEERROUTES=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes DNS1=<ipv4 address> DNS2=<ipv6 address> Also, added dns=none in NetworkManager.conf file. Whenever I am restarting NetworkManager, resolv.cfg gets updated and only ipv4 nameserver is displaced, whether I am expecting both the ips (ipv6 and ipv4 address to be present in resolv.cfg file. Any suggestion here, how to achieve that?? Regards, Shagun
