The dynamic IP problem and the DNS2P Dynamic DNS solution

Whenever a computer (or network-aware) device is connected to the Internet, the Internet Service Provider (ISP) associates that connection with an IP address. The IP address is a series of numbers that identify that particular connection to the Internet. Your ISP may change your IP address at any time and do so without notice. Because your IP address changes all of the time, it is almost impossible to run any kind of server on your Internet connection, such as remote web cameras, Remote Desktop, home automation, etc.

Consider the communication problems you would have if every time someone needed to telephone you, the phone company changed your phone number! The connection provided by your ISP is not reliable for remote access -- it is tailored for simple websurfing. Your ISP may provide a static IP address (a fixed address), but at a considerable expense costing hundreds of dollars per year. The ISP may not offer static IP addresses at all. So how would you connect to your home IP camera if the address changes all of the time?

DNS2P works with your existing Internet connection, tracking your dynamic IP address. When your Internet provider changes your IP address, the DNS2P client will publish your new IP address in your domain name record. DNS2P's DNS servers are very fast, so domain name update take just seconds to be available anywhere on the globe. After an update, whenever you (or someone else) types your domain address into some Internet software (such as a web browser), that software checks with DNS2P for your current IP address. Other people connecting to your site do not need DNS2P to find your server.

How to use DNS2P?

Here is an example of how DNS works when accessing a website. There are three parts necessary for someone to access a remote service on a server: domain registration, DNS service, and the actual service such as a website:

Domain registration

The virtual real estate - Purchasing a domain gives you a lease to a domain name from a domain registry like .com, .net, or .org. The domain registrar allows you to specify nameservers for that domain.


The glue - When someone types in a domain name like 'dyndns.com', a process called the domain name system (DNS) works to turn that name into a number called an IP address. Only with the number can you access a website.

Service (eg. web site, email, FTP)

The content - After the DNS is resolved, the client will access the service at the given IP address and return a webpage in this case.

DNS is a required "glue" for any Internet application or service where you use a hostname or domain name. DynDNS provides domain registration and DNS service in addition to mail services and network monitoring.
