Dns server not updating web address

Name server changes usually take 24 to 48 hours to fully start working.This period, called propagation, is the projected length of time it takes for root name servers and cache records across the entire web to be updated with your website's DNS information.

The following example should help you to visualize the process.

Similar to our telephone system, every active phone line has a phone number that is used to facilitate the connection of one line to another.

In each record in the zone, there is a Time To Live (TTL) value that specifies (in seconds) how long a resolver should cache the record.

One technique to reduce the time it takes for changes to propagate is to reduce the TTL value in the current zone prior to making changes, however the change in the TTL on the record itself will take the length of time specified in original TTL value to propagate before propagation period is lowered for further changes.

The same process applies for all other services (such as email, chat or games) on the internet.

DNS records function similar to a phone book, relating domain names with IP addresses so that these services can be reached.

Because of propagation, not all visitors will be directed to your new name servers on your new hosting account; some visitors will continue to be directed to your old name servers on your old hosting account until propagation is complete.

How quickly visitors are directed to the new name servers depends on their physical location, internet service provider and some luck; it is not something Host Gator has control over.

Also some ISPs configure their resolvers to ignore the TTL value specified in the record altogether and cache the record for a length of time that they specify instead.
