Problem: You are unable to resolve any domain names from within your VPS, or going to your IP does not bring up the default page. Or your are simply wondering what resolvers we use.

Solution: It is simple! login to SSH and execute the following command: nano /etc/resolv.conf

In that file put in the following content

nameserver 8.8.8.8

nameserver 8.8.4.4

now save by holding down CTRL+O and exit by holding down CTRL+X
