Who needs Sprint EVDO with Static IP address?

We just announced that is now able to provide static IP addresses for our customers Sprint EVDO data devices.

We anticipate that some of our customers who see the option on our Sprint EVDO Order Request Form, will wonder what its all about, so we figured it deserved another blogpost.

First a very brief explanation. "IP" stands for "internet protocol" and an IP address is a number that represents a participant on a computer network. One analogy would be to say "an IP address is to a computer, what a mailing address is to your home". Without the IP address, instructions from network device to another network device would have a hard time being delivered, just as mail being delivered without an address, usually doesn't get where you wanted it to.

When a Sprint EVDO data device like the Novatel U727 (now free with 2yr contract) establishes an internet connection to the Sprint network, it obtains a "dynamic" IP address. Being dynamic in this case, doesn't mean your device has a great personality... it just means that whatever IP address you were assigned on this network connection, may not be the same IP address the next time you connect. Dynamic = Random (from a pool of specific addresses that Sprint has assigned).

For most users... dynamic IP addresses are perfectly fine. In fact, if you don't already know that you NEED a static IP address for some reason... then you probably don't need a static IP address.

There are however, a bunch of valid uses for a static IP address. Most of those who need one, are companies who run "web applications" for their business that are used by people and devices operating on remote networks.

Network and application administrators must keep track of remote access through some sort of "white list", and if the remote connection has a dynamic IP address that changes each time a new network connection occurs, ensuring access from a remote connection can be a nightmare, if not downright impossible.

The same logic can apply in reverse as well. What if a central operation wants to keep communication channels alive with multiple remote users or equipment deployed in the field? It would be nearly impossible for central command to do that if the remote equipment did not have an IP address that stayed the same throughout reconnections.

Other more obvious uses for a static IP address involve the operation of a variety of different "server" applications like VPN, web, ftp, gaming, video, audio, email and a whole host of others.

However, since we all know that operating any kind of server is not what "Sprint Mobile BroadBand" EVDO service was designed for, we won't mention them here.... OK?

Pundits are sure to bring up "dynamic DNS" or "DDNS" services like those provided by -- and their argument is a valid one. Except when network administrators trying desperately to keep a vital line of communication open during a time-sensitive event, have to wait for a "propagation" to occur because of some malfeasant DNS server.

For those who consider communication with remote internet devices or salespeople or executives to be of the utmost importance, the option of a static IP address on a Sprint EVDO data devices is not an option -- its a must have!
