DNS
propagation is the process by which the computers on the Internet
update their records to reflect new Domain Names and site names. Once
your Domain Name has been propagated throughout the Internet, your
Domain Name can be accessed. The process can take from 24-72 hours. More on DNS : The Domain Name System is a global network of servers that translate
host names into IP addresses. Most DNS servers are UNIX machines
running BIND (Berkely Internet Name Domain) software; other platforms
and software are available. The software is composed of two elements:
the name server and a resolver. The name server responds to browser
requests by supplying name-to-address conversions. This information is
cached (saved for a predefined period of time). When/if it doesn’t know
the answer, the resolver will ask another name server for the
information. It continues to look up the ‘tree’ of name servers until
it finds a name server that knows the answer. Occasionally browsers can
timeout waiting for this process even when the propagation has taken
place. | |
