DNS Propagation is a process that replicates the intermediate locations distributed throughout the world while a domain is registered or name-server is changed. Before understanding DNS Propagation, you can read the basics of Domain Name System (DNS) and Name Server (NS). There are many theoretical and technical things related to DNS Propagation, but we will not go very deeper on DNS Propagation, rather we will discuss the practical things about DNS Propagation.
How DNS Propagation works
Any changes to DNS servers associated with a domain name (a new record has the same effect as a change) implies a new DNS propagation, so that the domain name will soon be linked to the machine that hosts that domain. That is, the service using the domain name will be inoperative during this period. This will affect both e-mail, as to the web.
Time Required for DNS Propagation
There are many aspects needed to be checked by the automated system to prevent hacking. Authorized Web Hosting Services with Cloud DNS usually take few minutes for a newly registered domain to be live and hardly 12 hours for an established domain name. More the reliability of the webhost and less important is the domain, less time will be required.
The usual traditional system with an average Domain Registrant and Mediocre Webhost it takes 24 -72 hours for DNS Propagation.
When we changed all our old existing websites to The Rackspace Cloud, except this one, all took lees than 5 minutes to complete DNS Propagation, where as this website took slightly less than 12 hours to complete DNS Propagation.
Free Tools to check DNS Propagation
There are many online tools to check DNS Propagation, but we prefer whatsmydns.net to visualize the DNS Propagation. Simply write the domain name without the http:// and www part and select NS from the dropdown menu and click search :
