Who provides Dynamic DNS Service?
There are numerous organizations in this area. Their
features, price, and reliability vary widely. So of the big names are
DNS2GO, TZO, NO-IP.
The problem with the dynamic IP address is that unlike
static IP address, they keep changing. Every time you connect to the
Internet, you receive a new IP address.
You could theoretically determine your
new IP address every time it changes and then modify your DNS records
manually with whoever is hosting your DNS records, this way you can maintain
a static name based address but this would be very time consuming.
Realistically, the only solution is to
use a "Dynamic DNS" service, currently supplied by
several companies.
How does this work / the role of dynamic DNS?
A Dynamic DNS service usually provides
you with a small piece of software (called a "client") that you install on
your computer and runs in the background. This piece of software
periodically checks with your PC to see if your IP address has changed. When
it detects a change, it notifies the provider’s DNS servers (called "name
servers") and changes your DNS records to reflect the new IP address. All of
this is done completely transparently to you.
On the Internet, you can find companies
who provide dynamic DNS (DDNS) service free (see
the DNS Providers List). For hobbyists, this is a good option.
However, if you are more serious about your web site, we recommend you pay
the small annual fee (typically $15-$30) for these Dynamic DNS services.
Companies who charge for the service can afford to create a much more
reliable service with 24/7 support.
Dynamic DNS providers typically include a free
sub-domain in their fee so you do not need to pay for your own domain name.
If you want to have your own domain name, several Dynamic DNS providers will
accommodate your own domain name for a small additional fee. We think this is very convenient and takes a
lot of the hassle out of the process.
Communication with the Dynamic DNS service’s servers is
always kept alive through the program running on your PC. It keeps a
critical watch of your connection and keeps the service’s servers in touch
of the latest address.
