Hi all;
I want to move my server from one ISP to another ISP.
My DNS names is will be same . But DNS IP adress will be change.
such as :

OLD ISP
ns1.xxx.com
64.74.58.96
ns2.xxx.com
64.74.58.97

NEW ISP
ns1.xxx.com
212.56.123.14
ns2.xxx.com
212.56.123.15

Will my clients set up again their NAME SERVER from their registerer company.?

If so, how can I easily solve this stuation?

Thanks.




:confused:

No, just as long as you change the IP addresses associated with your ns1.xxx.com and ns2.xxx.com name servers, your clients won't have to do anything.

yeah, this was a big confusion for me when i was learning a little DNS.

you tell your domain which DNS servers to use NS1 and NS2 etc...

then, you instruct the DNS server which IP address to point to, i had hours of arguments with my old host (*****) trying to get this done, he was saying it was a problem with my server and i needed to setup the domain resolution myself.

I tried telling them i didnt have a DNS server installed on my machine and that it was THEIR DNS servers i was using, and therefore it wasnt my problem because i didnt have access to change anything on them or add any pointers, as long as i could get to the web site via the IP it is a DNS problem, after about 3 days they finally pressed a key command and voilla, the domain came up on the next DNS replication.

PS: I have alot of ***** storys, they wil come out in the comming months for your enjoyment, i think maybe 1% of them are positive comments!

I am going to do the exact same thing next month. Moving my customers to another server. My DNS servers will also stay the same but the IP addresses will obviously change.

So you are saying that the only thing we need to do is change the IP addresses associated with the name servers' host names and that we do not need to change the DNS servers on each domain? Is the reverse lookup suppose to provide the domains with the new IP addresses? I just want to double check on this because I don't really want to have a mess going on later during the move. Also, why is it that when you are modifying domain records with some registrars they ask you to enter the host names for the name servers and also the IP addresses? Do they store the IP addresses? If that is the case then the reverse lookup thing will not work.

Thanks for your help ;)

Your clients will have to change the ip address with the DNS unless their domain providers do not hard code the ip address. For example for my domain I have to put the dns name ns1.something.com and then the IP address. If they don't match it won't work. Unless people are doing this differently, my answer will be that some clients may have to update the ip address.

as far i know about DNS (and my knowledge is limited) the following happens:

CLIENT > AAA.COM > NS1.ISP.COM > XXX.XXX.XXX.XXX(IP)
CLIENT > AAA.COM > NS2.ISP.COM > XXX.XXX.XXX.XXX(IP)

the CLIENT requests the web site, the name server tells the client what the IP address is.

If you change the server or IP address AAA.COM is hosted on and it is with the same ISP or you will be using the same DNS servers then you simply tell NS1.ISP.COM and NS2.ISP.COM what XXX.XXX.XXX.XXX(IP) actually is then this propagates to all of the other DNS servers (this update normally takes 12-24 hours).

please tell me if i have the wrong idea of DNS, cos id really like to know ;/

How do I know if the domain registrars are hard-coding the IP into the host names? Should I check each one of them individually?

Thanks!

Actually the DNS server IP addresses are registered with Network Solutions. For example, you have NS1.YOURHOST.NET pointing to an IP of 192.168.1.1. You can call Network Solutions and tell them that you want to change your DNS server IP addresses to be 24.95.227.1
in other words, your domain name server: NS1.YOURHOST.NET will now have a different IP address. Network Solutions changes the IP for the domain so that the ZONE MASTER servers point to a different IP. I understand this very clearly. So I currently have my DNS records on 192.168.1.1, create the exact same records on the new IP 24.95.227.1 so that once Network Solutions make the changes and the ZONE MASTER SERVERS start resolving NS1.YOURHOST.COM to the new IP address of 24.95.227.1, the records will already be there and no one will experience down time. After the IP address change and the name server move is completed successfully, then the records on the new server (new IP address) will have then to be changed in order to move the sites to their new IP addresses.

All this is clear, the doubt comes in with the actual domain names. I know for a fact that for instance Network Solutions (with recent domain registrations) does not require you to enter the IP address of the domain name servers associated with a particular domain, in other words, when you go to change the name servers for a particular domain you just need to enter the host name (NS1.YOURDOMAIN.COM) you do not need to enter the IP, so this domain finds the IP by doing a reverse lookup. On the other hand, some other registrars and even Network Solutions (with old domain registrations) require you to enter the host name and the IP address of the name servers.

So my question is: Do these domains need to be modified to show the new IP of its name servers or this works with the same reverse lookup theory?

VERY CONFUSING... ;)

Hi, i think i had totally the wrong idea about what was going on, and that this topic may have changed more to a TCP/IP - DNS configuration issue, but anyhoo... life goes on ;)

i mis read the question that you wanted to move 1 DOMAIN NAME to different DNS servers, but after careful consultation, i now figure its actually the DNS server IP address you are changing and possibly hundreds of dimain names you need to update!

I have been thinking about it, but its home time now (UK - 5:00pm) so im off home, and will be back later to finish this discussion off :)

That is actually what I am trying to do. Move about 200 domains over to a new server and change my DNS servers' IP addresses. :(

Moving 200 domains isn't fun if you are with a Registrar like Network Solutions.

Yuck.

Good luck. As the saying goes, you are going to need it.

I think the key to doing this is to ask somebody who has done this before with network solutions.

They will know the EXACT procedure involved I think NS may take things a little too literally and not query your mistakes with you.

Maybe there is someone who has done this before that can post how it went, and hiw much downtime there was

Changing the nameservers of 200 domains on networksolutions??? Ouch! Be prepared for thousands of emails back and forth as you struggle to make the changes you want with their outdated system.

Hey guys! I am not trying to change all 200 domain records, I just want to change my own Name Server IP addresses so that I can change the DNS to another location and move my customers to another server with relative easy.

I don't think it will be that easy though, and I don't know if I should really do it or leave them there and forget about this thing.

I can always leave them there and start putting new sign-ups on the new server. I just didn't want to have customers on a RaQ and customers on a Linux. That's all. ;)

I'm trying to do the exact same thing as bert and tezgelhasan and I'm looking for some advice on the best way to do this. What have you guys learned about doing this? I'd love to hear from you.

I've just successfully (the last 3 days) migrated about 50 sites to a new server. Here is what I've done.

1) Configure the nameservers of the new server using the same nameservers of my old machine and assigning new IPs to these.

2) Migrated (copy) all my sites to the new server and set up all e-mail and ftp accounts.

3) Edit my nameserver host record with NetSol. Here: http://networksolutions.com/cgi-bin/makechanges/itts/host

Follow the instructions carefully and after its done, your sites will resolve to the new server in 24 to 48 hours. All my sites resolved successfully except one that has a .ph TLD which I had to modify in our country's .ph registrar's database. All the sites (domains) I've transferred were registered from different registrars including NetSol, GoDaddy, Enom and DirectNIC and they all resolved successfully to the new server.

Note: If your nameservers are hosted in a different registrar (not NetSol), you have to edit your host record from that registrar.

Maybe this may not be that clear to any one, Edit means I've changed my old nameservers' IPs to the new ones and that's it.

This is simpler than you think.

You don't change the client's regsitrations(that will be too many), because the DNS server names stay the same.

What you need to change is the DNS host registration themselves, you do this using the HOST form with networksolutions.

I did the same thing. I ended up moving around 300 DNS records to a new DNS server. All I did was change the IP addresses for the DNS host names. It all worked out beautifully with no interruptions of any sort.

It is kind of weird though, but even now after a few weeks, when I do a whois on a domain registered with Netsol, they will show our name servers and will show the old IPs for the name servers. The domains resolve without problems, but I guess Netsol never updates their whois to show the new IPs!

Something else to consider is that on MANY, MANY times I have seen the netsol database behind. So that could always be it, but hey, if the DNS is working. It's all good. :D

Agreed! :)

opps...old thread

IF you've got primarily US clients, then you won't have to do anything at all, aside from change the nameserver ip addresses (for your own nameservers) at your registrar.

IF however you've got foreign clients, SOME countries require the full ip address of nameservers for looking things up. Hence, you will want to warn people of what's going on, and provide the ip's if needed. Usually, this isn't the case but it can happen that the ip's will have to be changed by your clients.
