Our VPS and dedicated servers are setup using our own DNS IP addresses, however if by mistake we didn't deliver it using our own DNS IP addresses, then feel free to use them:

HostSailor's private DNS IP addresses (IPv4) are as follows:

• 185.82.201.155
• 185.45.193.140

Please note, that you can only use them on HostSailor's services, it will not work for any public use.

For Linux a quick solution would be:

cat > /etc/resolv.conf
nameserver 185.82.201.155
nameserver 185.45.193.140
