DNS
The Domain Name System (or DNS) converts human readable domain names (like: professionals.cm) into Internet Protocol (IP) addresses (like: 183.194. 59.66).
Without DNS, the Internet would collapse – it would be impossible for people and machines to access Internet servers via the friendly URLs they have come to know.
DNS Propagation
Unlike a phone book, DNS records are commonly updated, meaning that a server’s IP address can change without affecting end users. Users continue to use the same domain name, and are automatically redirected to the new address. A DNS A or AAAA Record points a domain or subdomain to an IP, and a CNAME record points a domain or subdomain to another domain name.
After you register a new domain name or when you update DNS servers on your domain name, it usually takes about 12-36 hours for the domain name servers world-wide to be updated and able to access the information. This period is referred to as propagation. With next-generation DNS technology propagation can be reduced to minutes or seconds.
