Here's what I would do

# cp -p  /etc/sysconfig/network-scripts/ifcfg-eth0 /root/'somewhere'

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

erase all settings, paste below into the file and save

# systemctl restart network

IPV6_PEERROUTES=yes
DNS1=8.8.8.8
DNS2=8.8.4.4

# vi /etc/resolv.conf

clear all ipv6 nameserver settings

add:

nameserver 8.8.8.8

nameserver 8.8.4.4

Ok,
I tried the script with my ip for ip4 address and 8.8.8.8 and 8.8.4.4
and with my actual ip and hostname.

Still getting Error: NetworkManager is not running.

[root@mail ~]# sh qmt-host.sh

Call this script as follows (example below):
qmt-host.sh hostname ipv4.address ipv4.gateway
qmt-host.sh me.mydomain.com 192.168.0.2 192.168.0.1

Try running this: https://raw.githubusercontent.com/qmtoaster/scripts/master/qmt_host.sh

Or

Take a look here:

You must get rid of the IPv6 name servers

Do you think this may have something to do with my Centos Instance running on A digitalocean droplet?
