When using a video server with a dynamic IP address, you are
using your ISP's service to do something they didn't really design it to do. You may even be in violation
of your service agreement with the ISP. If you need "Mission Critical" 24/7, dependable, uninterrupted
availability, you should get a static IP address. And yes, they can be expensive.
That said, here is the other major issue with a dynamic IP address: it sometimes changes. If it
changes, the people trying to access your site from the internet will find that the link has suddenly
stopped working for no apparent reason. This issue we can deal with by using a gateway router, and
having some awareness of how the system currently works. Also be aware that if the ISP decides your
site is using much more bandwidth than their agreement allows for, or violates their service
agreement, they can easily shut you off. And then there's nothing we can do to help you restore
Normally, though, since changing an IP address is not a trivial exercise even for the seemingly all-powerful
ISP, you would be notified in advance of the interruption to your service. This is one of the
reasons we can even consider using the dynamic IP address.
If you've decided that a dynamic IP address will be adequate for your purposes. What next? You
need a gateway router. For purposes of this demonstration, we will go over the steps needed to
configure a fairly common router. With other routers, the steps will be
similar, but you may need to contact that router manufacturer for specific details. (In time, even this
Netgear router's software will change. These are technologies that evolve very rapidly!)
Here, then, are the basic steps involved in this installation:
• Set up your LAN. This basically means getting your computer talking to your router.
• Configure your router to allow access from the "outside world".
• Trace your dynamic IP address to find the host name. This is what people will type in their browser
to access your site.
