For 3 servers, you can only run 3 name servers ~ How do you get 6? :stickout:

By doing that, it provides redundancy to dns ~ :fairy:

6 nameserver:

ns1.domain.com and ns2.domain.com -> server 1
ns3.domain.com and ns4.domain.com -> server 2
ns5.domain.com and ns6.domain.com -> server 3

the domain.com is hosted on the first server and i have duplicate the dns file on each server, is it ok? if the server 1 go down, will go down also the other box?

people usually only run two name servers on one server if they dont have any other servers to run name servers on.

The reason for this being that most registrars require two dns servers.

So you may as well just have 3 name servers, 1 on each, since running two name servers on each will not increase redundancy unless you have, for example, two different connections to each server (6 connections, 6 name servers, over 3 servers).

Also, if ns1 goes down (probably ns2 will as well using ur method as they are on the same server) then ns3 +4, and ns5 +6 will continue to server dns requests unless your unlucky enough to loose all three servers at once (it happens??) :P

not sure if you mean dns in your above question though, if your talking about a website, and its hosted on ur ns1 + ns2 server then the site will still go down.

the domain will still resolve, but it will resolve to the ip of your ns1+ns2 server which will be down.

I recommend you setup 3 name servers then ~ Because setting up 2 on the same box is just the same as setting 1 on a box ~

Yes when 1 server go down, the other two takes over~

This only provides DNS redundancy ~ It doesn't keep your site online if it goes down ~ You have to keep two copies of the site on both servers in order to do so ~ :fairy:

If you want to keep your site online when one server is down and the other servers take over, you have to have copies of sites on the 3 servers ~

If you just want to have DNS redundancy, then there is no need to have make copies of the site and put on all servers ~
