JustHost I’ve just bought a domain name and i’ve hosted it with a separate free web host site. I’ve changed the nameservers but i don’t know how long it will take?
Any ideas?
Chosen Answer:
Hello,
The changes may take 5 minutes – 48 Hrs. depends on ISP ( Internet service provider ).
There is no role of domain or hosting provider in this. It is completely depends on ISP ( Internet connection ) you use. ISP’s cache the DNS of domains, which cause old records to show.
In most ISP they update DNS within 24 Hrs. but few ISP may take upto 48 Hrs.

It can take up to 24 hours for the DNS change to propagate.
Typically 24 hours, some sooner.
Usually pretty quickly – an hour or so usually – although it depends on how often people’s ISPs change their databases – AOL for instance can take until the next day.
Depends on where you have registered the domain. If you have it registerd at godaddy, you should typically get the name servers changed in 5 minutes.
Most other registrars must be able to do it in short time, and every registrar should be able to do it in under 24 hours.
You will also get a email notification for the same. You may then go ahead and add the domain to your control panel.
It depends on your ISP. ISPs generally refresh their DNS cache anywhere from hourly to daily. So it could be anywhere from 1-24 hours.
I just got a domain at http://www.fiber9.com and it was available in 3 hours
