assuming you have the ips how many nameservers can you create ie ns 1 ns2 ns3 ns4 ns5 etc is there a limit? using enom by the way.

I know eNom offers 5 name servers of their own. I would guess the theoretical number that could be registered with the root servers in more than most of us would ever need to use.

But how many name servers would you possibly want, and for what reason?

With NameCheap we allow you to add up to 10. I don't think there's a technical limit but that's just all that we allow. I think eNom works the same way. There's not any real limit that I'm aware of.

Personally, I have seen up to 5. Where it really counts, you just need two, a primary and a secondary. Mostly you dont get passed the primary unless that server goes down or something odd happens.

I've heard you can put two nameservers on one ip address ... is this true? I think I've also heard you can have the nameserver the same ip address as the ip address you use for your web site/server? Not sure if this is true or not.

Although obviously if the first nameserver goes down, the other one would too at the same time (lol).

Yes, multiple logical servers can share the same IP address. including having a nameserver and multiple logical hosts on the same IP address.

You can have two nameservers on the same box, though it violates the spirit of the rules requiring at least two nameservers.

Having two nameservers on the same IP address violates the rules in fact, and I don't think I've seen this, though it might be possible.

The purpose of multiple name servers is redundancy. If you were to advertise that you have four nameservers, but all the nameservers were on the same box it would be fundamentally dishonest. If they were on different physical machines but the same pipe, it wouldn't be much better.

rapidtransit, thanks for your response to my question. I was just curious about this, since someone had told me once regarding this. Even though I was curious, I do not intend to do something like this. I don't think anyone really would do this... there's no point. Thanks again for your response to my question, rapidtransit!
