Hi,
I am a confused newbie.
Here is the scenario:
My WHM box is identified as:
ns1.dnsserverfl.com IP 65.19.139.233
ns2.dnsserverfl.com IP 65.19.139.234

I have a reseller/domain acct on the box:
ns1.blazingfast-communications.com IP 65.19.139.233
ns2.blazingfast-communications.com IP 65.19.139.234

Question(s):
1. It seems to work, that is the way I understood my dedicated server host to tell me how to set up the zone files... Can I, Will I set up all reseller accounts on the box with the same IP numbers as above for their nameservers? for example:
ns1.newreseller.com IP 65.19.139.233
ns2.newreseller.com IP 65.19.139.234

Be gentle, I am not a tech.

Best Regards,
Mike

No every name server has to have it's own IP address.

Ummm.... it appears you may have been giving some incorrect information....

From what I'm finding:

ns1.dnsserverfl.com's IP should be 64.91.239.151
ns2.dnsserverfl.com's IP should be 64.91.239.159
ns1.blazingfast-communications.com's IP should be 65.19.139.234
ns2.blazingfast-communications.com's IP should be 65.19.139.235

From what I understand, you can't have 2 different nameservers pointing to the same IP. You'll need to get 2 more IPs for each set of nameservers you need to setup.

Good luck!

WebmastTroy:
ns1.dnsserverfl.com's IP should be 64.91.239.151
ns2.dnsserverfl.com's IP should be 64.91.239.159

That is my old box, still online. I have not changed the IP numbers yet, I need to move all the accounts to the new box first.

Yes, you can use the same IP for differents domain nameservers.

I mean.

What you can't do is

ns.domain.com 64.91.239.151
ns2.domain.com 64.91.239.151

but you can do

ns.domain.com 64.91.239.151
ns2.domain.com 64.91.239.152

ns.domain2.com 64.91.239.151
ns2.domain2.com 64.91.239.152

Jedito;
That seems to be what my dedeicated server host is trying to explain to me, and my 'guess' is that it works because... all of those nameserver IPs resolve to say 64.91.239.21 for example, which would be my box's assigned IP number on the host's DNS server, right?

No :)

The thing its that now registrars do allow to use shared IP to register nameservers, I think that they changed the politic at the beginning of this year. Before that, you has to use a dedicated IP per nameserver, but now, luckily, its not needed anymore.

I've never heard that before. Well....that makes my life a little easier. :)

I'd try it out, but Dotster won't give the SUCCESS page for some reason. It keeps timing out. :confused:

In all honesty,
What is causing my confusion is that I have domains (hosted accts) resolving correctly, no matter which way I do it.

1. Using the same IP numbers for the reseller as I use for my box.
2. Assigning the reseller different IP numbers for his name server.

PS at least it works on that way at the 2 WHM dedicated server hosts that I now use.

Has been already discused in this thread awhile ago.

Thanks all,
I just read the reference post. It is now clear to me that I can do it either way (been doing it both ways for a while anyway, I just did not understand it).

I don't have any trouble assigning the same IP numbers to any number of nameservers at godaddy.com.

----------------------

At GoDaddy, you can assign more than one name server, even on the same domain, to the same IP address. So you can do:

ns1.example.com 127.142.128.35
ns2.example.com 127.142.128.35

...and even at the same time, you can do:

ns1.example.net 127.142.128.35
ns2.example.net 127.142.128.35

I don't know if any other registrars allow you to do that, but if you know any other registrars that do, I'd like to know. If all registrars would allow that, we all could save a TON of IP addresses.

Yes, but doesn't that defeat the purpose of having the two nameserver requirement to begin with?

If they're all going to allow you to use the same IP address for ns1/2.domain.com then they might as well change the rules so you only need one nameserver per domain.

If they're on the same server anyway, what's the point?

This is possible because of the IP adress shortage. I'm sure ARIN has something to do with it...

True. The original point of the separate DNS server architecture was to ensure your site stayed up if one of the DNS servers failed, but as most people have their DNS server on the same machine as their site then there isn't much point having two DNS servers each taking up precious IP space.
