In a very simple explaination, Domain Name Propagation means Domain Name Updating Process.
You need to wait from 5 minutes upto 72 hours for any changes made to the domain name, such as :
- new domain name registration
- change of details
- domain transfer
- change DNS info and so on.
It all depends on how often the ISP (Internet Service Provider) update their DNS Records.
ISP is the company you are using to connect to the Internet from home or office.
In Malaysia, we now have two ISP companies :
- Telekom Malaysia (Local ISP)
- i-Skill Dynamic Sdn Bhd (International ISP)
Domain Name Propagation is the process of your registrar (or the website you used to register your domain name) handle the changes made in your domain name to their DNS servers, ISPs acquire DNS Records from the DNS servers, and other ISPs (ISP from other company or other countries) also need to update their DNS Records.
Some ISP update their DNS Records more often than others (better service) and receive changes faster. As a result of this, often you will not be able to get to your website by its' domain name but a friend can (because your friend is using a better ISP service). Just wait until the changes propagate (update) to your ISP.
All other Broadband service providers such as Digi, Maxis, Celcom, etc are not ISP.
WiMax such as P1, Redtone are also not ISP.
