how long does it take for nameserver changes to propagate?
 

When I register a new domain it usually resolves instantly, as it has been doing for a year or so now. However after changing nameserver info for some existing domains I noticed that it's still pointing to the previous server; do nameserver changes still take 2-3 days the same way new registrations used to?

it's supposed to be instantaneous now. But still they say that about 36 hours, to be safe

its even faster than it used to be

it might be my ISP but my chages show up within 12-24 hours now.


if you wanna check search google for "looking glass" and try tracerouting from diff points in the world.

Nowadays 30 mins or so

Some ISP's don't update immediately after you change while others do. I used to keep AOL installed because they get DNS changed instantly.

more than likely it has resolved already, it is your ISP that has cached it to the old NS. Have someone else check. If they see it on the new way you should edit your HOSTS file

If you always use www, try without, or visa versa

I thought that it was instant as well. But maybe not.

the reason you want to change your HOSTS file is because the more often you look, the longer the cache will last

if you are the owner of the nameservers you are pointing to, then you may need to push your domains or check refresh settings...

domains that havent prop'd in 2-3 days is a problem..

Depends on your registrar.

why not tell us the URL and let us tell you what we see?

It's pretty fastnow a days. I'd say about 6 hours.

There are two things that delay the transition...

(1) How long it takes for the root servers to update and return the new name servers in response to client queries

(2) How long it takes for existing DNS caches - at ISPs - to flush the old records, and fetch again from the root servers (thus returning the new ones)

Have the IPs of your sites changed or just the name servers?

thanks for the info!

here's the url to that looking glass site: http://www.traceroute.org/

the interesting thing is that when I look up the domain on that site, it shows it resolving to the new server. yet my tradescript (on the old server) is showing no noticeable loss of traffic, indicating that most or all of the visitors are still seeing the old server. normally this wouldn't be a concern since I would just mirror the old server to the new one, but this site was on a virtual account that I can't transfer through cpanel so I need to reinstall a script (hopefully quickly) after the nameserver resolves.

both IP and nameservers have changed

It's a pain in the ass but if you sign on through AOL you can upload your script. I've had to do this a few times before. Either that or use the IP to ftp in and edit.

thanks, this isn't the site I'm putting the script on but it's another that was transferred to this same new nameserver. I set an extra file on the new server that does not appear on the old one.

http://www.thiskiss.net/ads1.html should display an html page if it is resolving to the new server, or a 'page cannot be found' error if resolving to the old server

I see " banner ad1 "

Just edit your hosts file, it will make things easier on you, and get rid of the cache your ISP has (and that is what your problem is)

it is an ISP cache, trust me

thanks, one more question; what is the hosts files and how do I edit it? :)

a googled result just said to look here c:\windows\system32\drivers\etc\hosts but that file is empty

yes, it probably is empty. You are going to edit it so it isn't any longer

your.new.IP yourdomain.com

or

your.new.IP www.yourdomain.com

don't do both, that way you will be able to know when the cache is gone and you can change the hosts file to be empty again (do not ever delete the hosts file)

The format is IP {whitespace} hostname.

214.24.125.12 www.ihatebadadvice.com
214.24.125.12 www.editingyourhostsfilewouldbestupid.com

Etc.





P.S.

There is NO reason for you to edit your hosts file.

What the hell are you talking about?

If his ISP has his domain cached with the old NS, and he doesn't want to have to type in the IP address how would you suggest he see the new server?

His hosts file is currently empty. he is going to edit it so he can see his site with the new IP and NS.

If, after his ISP has cached the new IP/NS he should clear the hosts file, not just delete it

I know what he's talking about...

I'm wondering what the hell you are talking about. What catastophic system failure would occur if one deleted their hosts file and why should it NEVER be deleted?


P.S.

I never saw him ask how to force resolution to a new IP on his local machine. I saw him ask how long the update should take. Maybe I missed it, though...

I'm trying to get a script installed on the new server which is hard to do if the site resolves to the old server, since the install is all done through a browser and the script itself referances a url on the same domain, not an ip... so the information is appreciated

thanks baddog

To be honest, I doubt anything would happenif he deleted it, but I don't know that you can just add it again later. Never tried. Just don't think it is a good idea for someone unfamiliar with things like that to just delete them.

You are honestly unsure if you can go to c:\windows\system32\drivers\etc (/etc) and create a file named 'hosts' with no extension? Your second point is well taken.


Glad you're getting things worked out AmateurFlix.
