| Posted by ramavps, 11-16-2007, 09:35 AM | | Hello Every Body
i am facing a very strange problem, i changed my domain name server from 4 days ago from the first hour our partners at USA and at UAE see my website under the new ip of my new name server after while we found all the lines that connected through my ISP my local ISP pinging to the old ip of the old name server
till now from 4 days every one can see my website under the new ip except me and all the line that with my ISP
the question now is how can i be sure that all the world can see my website under my new IP to be sure that the DNS has been propagated 100 %
thanks for all

Generally ISPs has DNS servers that caches DNS entries for a short time, so until TTL (time to live) of your SOA entries was reached ISP's DNS will show your old settings. Anyway, 4 days is a lot of time, check your TTL time on DNS server and if this is right, ask your ISP for this issue.
You have no way to be 100% sure that all the word can see your new IP.
Best regards, Creaws.

If you don't have access to the DNS server, ask for it value to your hosting company or ISP.
Comment: The Ping TTL value is the time to live for IP packets trough a routed network. This value is for other purposes.
Best regards, Creaws.
