What nameservers should I use in my resolv.conf file?

Question

It is very important to ensure your /etc/resolv.conf file is configured with proper nameservers in order for DNS resolution to function correctly on your host. What should these values be set to?

Answer

You should reach out to your web hosting provider or systems administrator to determine what nameservers should be used in this file. However, you can default to using Google's nameservers if you are uncertain or are in a hurry to get them working properly:

[root@host]# grep nameserver /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
