How to add DNS server in Linux?

How do I add 8.8 8.8 to DNS server Linux?

I have one Linux virtual machine which is acting as DNS.

My host is using 8.8 and 8.4 for Google public DNS. I want to add the 8.8 address to the host's resolv.conf in order to get rid of the 4.2
I tried adding nameserver 8.8 8.4 to /etc/resolv.conf, restarting the machine but it didn't work. It's probably a simple thing I'm missing. Any suggestions on how to do this? Thanks

You can only add static addresses into resolv.conf if you're using a resolver that provides this capability (nameserver doesn't do it).

However, you can always add nameservers in your network interface's /etc/resolvconf/resolv.d/tail file. For your VPS it would be eg:

How to add local DNS entry in Ubuntu?

I am using Ubuntu on my desktop and laptop. I use static IP for the router and use my own local network DNS as well.

There are times when I can't even access Google and youtube with my home network DNS. That is the time I need to add local DNS for my server and router. How do I add a local DNS?

I have tried this command: sudo gedit /etc/network/interfaces. And added this line: auto eth0. After that I restarted my computer and then I could connect to the internet and also connect to my local network. But after that, every time I do a system update, I have to remove the local DNS again and repeat the same process again. The local DNS entry in the above file will be removed after the update is completed. What can I do to prevent this and keep the local DNS entry for the entire system?

How to add DNS server in Linux?

I am using a Linux system (Fedora) and I need to add some DNS servers. I am using DNS with a router and my desktop. The router has 2 IP addresses - 192.168.xxx and 192.

How can I add DNS servers for these two IP addresses? I have tried to edit the /etc/resolv.conf file but it does not work.

The resolvconf package is used to manage /etc/resolv. It can also add new nameservers.
# yum install resolvconf. You may have to edit /etc/sysconfig/network-scripts/ifcfg-eth0 to set IPDNS=192.xxx, IPDNS=8.8, and IPDNS=8.4 (where 8.8 and 8.4 are example nameservers).

When you use network-scripts/ifcfg-eth0, you are configuring the interface eth0. You need to make sure that the interface name is correct.

Once you've done this, your system should be able to resolve hostnames using the IP addresses in your router configuration.
