Dynamic DNS Setup
It is difficult to remember the IP addresses used by computers to
communicate on the Internet. It gets even more complicated when
ISPs change your public IP address regularly, as is the case when the
Internet connection type is Dynamic IP or PPPoE with Dynamic IP.
If you are doing some web hosting on your computer and are using
Dynamic IP, Internet users would have to keep up with the changing IP
address before being able to access your computer.
When you sign up for an account with a Dynamic Domain Name
Service (DDNS) provider, the latter will register your unchanging domain
name, e.g. MyName.Domain.com. You can configure your router to
automatically contact your DDNS provider whenever the router detects
that its public IP address has changed. The router would then log on to
your account and update it with its latest public IP address.
If someone types in your address: MyName.Domain.com into their web
browser, this request would go to the DDNS provider which would then
re-direct that request to your computer, no matter what IP address it
has been currently assigned by your ISP.
The Dynamic DNS service is ideal for a home website, file server, or just
to keep a pointer back to the USB storage disk connected to your
router so you can access those important documents while you are at
work.
