Dynamic DNS (DDNS) Service

About Dynamic DNS (DDNS)

Think of the phone system. When you dial a number, it rings at a particular location because there is a central numbering plan that ensures that each telephone number is unique. The world IP address schema and DNS work in a similar way. If telephone numbers, IP addresses, and domain names were not globally unique, phone calls or e-mail intended for one person might go to someone else with the same IP or domain name. Without uniqueness, both systems would be unpredictable and therefore unreliable.

Having a dynamically assigned IP address is like having to change your phone number twice a day. If other people need to connect to your computer, they would have no way of knowing your current number. "Imagine if the phone company changed your number twice a day. People would have a very hard time calling you". Dynamic DNS (DDNS) works much like an old style phone operator, directing internet users to the appropriate internet server, despite the fact that the server's IP address is continually changing or dynamic.

With the Dynamic nature of the world's current IP address schema, users cannot readily access web and other services since the server's IP address is always changing. Furthermore, IP addresses are difficult to remember. Dynamic DNS (DDNS) has gracefully addressed many of the problems associated with dynamic IP addresses.

Old design decisions also limit the theoretical number of IP addresses even more, and until IPv6 hits the mainstream, the current shortage of IP addresses will only worsen. What does this mean, you may ask, and how does it impact me?

Since there is a limited number of static or dedicated IP address, not everyone can have their own static or dedicated IP address. Some Internet Service Providers might let you have a dedicated IP, but they'll likely charge you extra for it.

Dynamic DNS circumvents most needs for static IP addresses. This is very useful since almost all IP addresses are dynamically assigned. Simply put, there's only so many numbers out there, at least as far as the computer is concerned. (Basically, each of the four parts in the address can only be between 0 and 255.)

Benefits

Static IP addresses are expensive

With the limited number of static or dedicated IP address, some Internet Service Providers (ISP) offers a static IP for a premium. An average cost for a static IP address is over $99.00 a month.

Multiple business or home applications could use DDNS.

If a business or home user needs to run software such as Web Servers, FTP Servers, Game Servers, Email Servers, online video conferencing, voice conferencing, or if they need to allow access to their networks for things like connecting to computer systems through remote access, enabling VPN's between branches, keeping track of branch office print servers, then they would require either a static dedicated IP address or Dynamic DNS (DDNS).

IP cameras are particularly reliant on Dynamic DNS (DDNS).

If you live in a relatively large town, there are likely millions spent each year by local businesses that require static IP addresses. Most do not know about Dynamic DNS (DDNS) services, and many would be happy to know that there is a qualified alternative to the thousands of dollars they spend each year for static or persistent IP addresses.

How to enroll

(Dynamic DNS) DDNS servers provide client computers with static DNS names, even if their IP address is dynamically assigned. 2MCCTV has created this DDNS service for our customers to help them manage their dvr's and ip security cameras. This software application is very easy to install and will communicate with our servers to update your dynamically changing ip address saving you money over having a static ip address. After you download and register the software, you will want to get a domain, like yourname.dyn.2mcctv.com, and it will automatically reroute you to your dvr or ip camera that has been set. Having your own domain name is easier than having to memorize your dynamically changing ip address.

For a low initial cost, 2MCCTV provides DDNS (Dynamic DNS) service for home or business networking needs.
