If you have properly updated your DNS information to use Dreamnix.com's name servers(NS1.SITE4NOW.NET, NS2.SITE4NOW.NET, NS3.SITE4NOW.NET) yet the domain does not work or is still
pointing to the previous hosting company, you are likely experiencing
DNS Caching.
After you make the update with your Domain Registrar, the internet will
not instantly recognize your new domain name information. There are
hundreds of domain registrars and all of the modifications and new
registrations need to be synchronized with the central (root) DNS
servers. This process typically takes less than a day, but can take as
long as 72 hours.
Therefore, if you run a whois lookup
on your domain name, it may be properly updated in the whois database
offered by your Domain Registrar. However the central DNS servers may
not have been updated yet.
Additionally, all Internet Service Providers maintain their own local
DNS cache. So even if the central DNS servers have been updated with
your domain's new name servers, the ISPs local DNS servers can still
cache your old information. In which case users of that ISP will still
be taken to your previous location.
It takes from 24 to 72 hours for your new domain name location to
propagate through the entire internet. You may notice that some users
will be taken to your new location at Dreamnix.com, while others
will be taken to your previous location.
This DNS Caching period is a normal occurrence and is unavoidable.
Additional Information
Mail servers will also send email to different locations depending on
the local DNS cache they are using. So it is possible that you may not
get all of your email during this DNS caching period. We recommend that
you immediately set up all your email addresses, duplicating the email setup at your previous host.
While your DNS changes are propagating, you can use the FTP
address to upload your files and your temp URL to view your
site. FTP address and temp URL can be found from Control Panel.
