I just upgraded to a new VPS with GoDaddy. My old onw was with them as well. I setup the DNS on the new machine just like the old one, but with the new IP address. Is there anything I need to do other than that to get the new DNS information to propagate? Did it last night at about 10:30, but when I use DNSStuff.com it still shows the old IP. Do I just need to wait?
Thank you for your help.
This is pretty vague. Are you saying you want to change the hostname of your VPS from the IP of the old VPS to that of the new one?
If so, you need to change the hostname record in the DNS for the hostname's parent domain, wherever that is.
When you say "you setup DNS on the new machine" do you mean you are running a nameserver on it? Is that with the intention of it acting as an authoritative nameserver for some domains (presumably hosted on that machine?)
If so, you would need to update the nameserver glue record, again within the domain that is the parent to the nameserver hostname.
There are even more possibilities. You have to be a bit more specific I'm afraid.

I am a noob in the VPS-DNS world.
I purchased a VPS (with one ip) and logged into WHM to setup for production. I configured nameservers to "ns1.a-domain-i-have.com" and "ns2.a-domain-i-have.com".
Then logged into that domain account at my register where I
- set default nameservers from the registrar
- in DNS manager I set ns1, A , my server IP and ns2, A, the same server IP
After creating a host account in WHM using "another-domain-I-have.com", I registered "ns1.a-domain-i-have.com" and "ns2.a-domain-i-have.com" in the custom nameservers.
But my new website refuse to work/ nothing works, I did all these based on the understanding of tutorials I googled.
I have tried
- reinstalled the VPS
- used the default nameserver that came with the VPS host. Although, this nameserver ip is unknown.
- update cPanel
I need some help!
I already got it. It works now. The steps I mentioned aboved did it. Maybe am supposed to take this down but I'll leave it for newbies like me.
I am in the process of moving the website traffic for adadarters.com from old host to new host. We are keeping old host for various reasons, including mail and ASP files that we don’t want to move, so I simply modified the A record to point to the IP for new host. After 10 hours it has still not really propagated, even though it appears that it has. I have been doing ipconfig /flushdns all day.
What’s happening is that adadarters.com serves up the NewIP (74.220.215.66) and www.adadarters.com serves up the OldIP (65.254.231.127). If you try and type in the URL without www, it appears to redirect to www and sends you to old host.
The way I figured out was nslookup adadarters.com 205.171.3.66 (my ISPs IP address) vs nslookup www.adadarters.com 205.171.3.66.
Also, a traceroute to adadarters.com vs www.adadarters traces the route to new and old IP addresses.
New host says DNS looks fine to them. Old host says settings look fine to them too, and that I just need to wait longer for it to propagate. But why would www propagate differently than non-www? I think they are just putting me off because they don't know (one reason they are the old host).
Any ideas about what might be happening?If by some chance this has resolved by the time you look, the old host files have the logo on right, new has logo on left and is a WordPress site.
This is off-topic here, you should've asked on https://superuser.com/
Your computer probably cached the old DNS. Try ipconfig /flushdns
The problem clearly is not in your ISP's DNS:
$ nslookup www.adadarters.com 205.171.3.66
Server: 205.171.3.66
Address: 205.171.3.66#53
Non-authoritative answer:
Name: www.adadarters.com
Address: 74.220.215.66
I have a more specific DNS situation than it is usually asked, and have extinguished reading resources already. At this point I'm pretty desperate. Here is the scenario
Get a computer with OLD IP (let's call it that) for a new domain. Set up for the first time its own ns1.mydomain and ns2.mydomain successfully. They had propagated and all was fine whether you entered mydomain.com or www.mydomain.com
Fast forward a few months, and have to upgrade to new machine, with NEW IP. Soon, I will no longer have access to OLD IP machine. I make an exact copy (went over it many, many times) of the DNS configuration from the old machine on the new one, replacing OLD IP with NEW IP
Since the old machine is still running, I change its DNS records to point to the new IP instead, because I figured it would help 'transfer the authoritative dns' to the new machine. Of course, I have no real grasp of how the authoritative dns is set, even with all my reading.
What followed is that after a few hours (it has been more than a day already by now), typing mydomain.com points to the new IP, while typing www.mydomain.com will keep pointing to the same old one. On the domain.com.zone file, on both OLD IP and NEW IP computers, I have a record for www IN CNAME domain.com.
Also, going to http://www.intodns.com will say "Looks like the A records (the GLUE) got from the parent zone check are different than the ones got from your nameservers".
Doing a nslookup, will say that the authoritative answers can be found at my nameservers, but they still point to the OLD IP
Finally, still after 24h, if I do a service named stop on the OLD IP computer and go to http://www.internetsupervision.com, it will fail finding the DNS for mydomain.com or www.mydomain.com. Yet, if I turn named service back on, it will find it again immediately.
I believe my lack of understanding of the authoritative DNS is preventing me from making a new IP machine start broadcasting the new DNS records. As I've said, I still have access to the old machine, but only for a few more days.
If anyone has any insight to help me in this case, I appreciate. I really don't know what to do any more and have nobody to turn to. Why is my new, updated DNS IP not propagating properly?
The servers telling the world where to go to find authoritative data for your domain are the servers for the parent domain of your domain. That is, if you want to change the IP addresses of the name servers for mydomain.com, you need to change those addresses both on your own servers and the servers for .com. The latter is typically done via an interface (usually web) provided by the people you pay to get the domain in the first place.
Apologies if this is too basic, but you don't mention changing your delegation anywhere in your question.
After moving to the new server, for sure, I need to change the DNS settings at Cloudflare to the new server IP address.
Cloudflare control panel can show the new ip address that I've setup, but when doing some dig command, the ip address returned still the old one. Although I already request directly to the ns specified by Cloudflare.
here is my dig command:
dig thedomain.tld #cfns.ns.cloudflare.com
Strangely, when I pause the cloudflare, I can see the new ip from dig command above.
any hint to solve that ?
It actually sounds like you may be running into some recursive DNS caching issues. We push out IP changes that are made in your DNS settings very quickly (minutes or less), but it may take a little longer to push out everywhere.
My host has changed my IP address in my VPS hosting. This was a planned change they asked me when will it be good for me.
When they've changed my IP I managed to change the 2 nameserver's IP at my domain host so they will point to the new ip now.
I'm using kloxo and I have changed the DNS records for my main domain. It is working correctly with the new IP address now.
However I'm hoiting other domains there aswell but they just can't seem to be loading those sites...
Can anyone please tell me what could be the problem? Maybe change their DNS to the new ip aswell? (But if I do that, won't all my domain point to the main domain?)
The DNS records for those other domains will also need to be updated. Provided that you've correctly set up your VirtualHosts (or equivalent), then changing the A-records of the other domains to match the new IP of your server shouldn't cause any issues.
