Helping people with computers... one answer at a time.
Your IP address is set by your internet provider so that they can identify your computer and send you information from the internet. Changing it to set up a static IP address may not have the result that you expect.
I currently have internet service with AT&T and high speed. I just installed a CCTV (Closed Circuit TV System) and the tech advised that I need a static IP address. AT&T wants to charge me an outrageous monthly fee for a static IP address. I found info on the internet on how to set up the static IP address. If I do this myself, will I lose my AT&T DSL service or will I still also have to have a dynamic IP address and the internet service? Thanks in advance for any info you can provide.
In this excerpt from Answercast #13, I describe the way static IP addresses work and question if it is needed for your connection.
There's a difference between configuring your machine or your router to respond to a static IP address and actually having a static IP address.
In order for things to be found on the internet (your machine, for example, in this case), your ISP has to know how to route the data to your computer. If you just set a new static IP address on your computer or on your router, your ISP won't know about it and it won't know how to get data to you.
As a result, yes, you will lose your connectivity when that happens.
A static IP address, in order to be useful, must be assigned by the service that you're connecting to (in this case, your ISP.)
In this case, AT&T has to actually assign you the static IP address. They will tell you what the IP address is. It's only then that, with that IP address in hand, you go into your router or your PC and configure that static IP address for use.
Unfortunately, there's really no way around this. The static IP address, like any IP address, is assigned by your internet service provider. If they want to charge an outrageous fee for it, they can.
It is additional work on their part. Non-static IP address are all handled automatically. Static IP addresses have to be manually assigned, so there's manual intervention and some amount of maintenance involved in making sure it continues to work.
So, unfortunately, I don't know a way around this for you.
I would question whether or not you actually need a static IP address. It's very possible that your dynamic IP address won't change very often and that could be enough.
Ultimately, it all depends on exactly how you're attempting to use this system and why the service person suggested a static IP address in the first place. Sometimes, there are workarounds, but the workarounds depend very heavily on exactly what it is you're trying to do.
