Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Should I ask for additional IPs for nameserver?

[pcom]

Hi,

Another newbie question here,
Along with the dedicated server, I was given:
1 primary IP.
3 additional IPs allocated for 3 sites of mine.

My question is: I want to assign the 3 domain names to my nameserver (ns1.mydomain.com & ns2.mydomain.com). In order to do that, should I ask for 2 additional IPs to register as nameservers? Or can I just use 2 of 3 given IPs?

Thanks for reading!

You can use the 2 IPs.

Thanks!

Hmm.. can I use all four the IPs then? The more the better, right?
So, I'll register:

ns1.mydomain.com ---> primary IP
ns2.mydomain.com ---> additional IP 1
ns3.mydomain.com ---> additional IP 2
ns4.mydomain.com ---> additional IP 3

Is this ok?

Your goal is to have seperate machines w/ seperate IP addresses. This way, should your primary DNS service die, there are failsafes to fall back on.

In my opinion, you really only require two DNS servers. You can use the other IP addresses for other services / applications.

If you are keen on having more than two DNS servers, my suggestion would be an off-net backup namesevice offered by most ISP / hosting companies. Alternatively, there are also free solutions you can use (zonedit, everydns)

Out of curiosity, are you setting up your own servers, or is your hosting company providing anonymous DNS for you? If your case is that latter, then there is no point to using your IP addresses, as your hosting company will more than likely just alias these to there nameservers.

Good luck.

I just got an unmanaged server, so I'm trying to set it up myself.

So, which 2 IPs should I use?
The primary IP + one additional
OR ..
just take 2 of the additional IPs?

Does it matter?

Here is what I've done ....

ns1.yourdomain.com -> primary IP
ns2.yourdomain.com -> second IP

Cheers.
