IP Addresses Simplified
When it comes to IP, Your internet service provider (ISP) can either assign a static or dynamic IP address for Internet Protocol networks.
Static IP Addresses
Static IP addresses are constant—they never change. Having a static IP address is convenient, because you will always know what your IP address is every time you connect to the internet, and do not have to worry about it changing like a dynamic IP address. Most ISPs charge a monthly fee for you to have a static IP address and prices vary by ISP.
Dynamic IP Addresses
Dynamic IP addresses change—they are dynamic and never stay the same. Dynamic IP addresses change based off of the internet service provider (ISP) and their protocols. You could have a dynamic IP address that changes every 5 minutes, or it could change every 5 days, monthly, or some other change frequency, as the ISP deems necessary. Because dynamic IP addresses change, finding out what the IP address changed to can be difficult, unless you enlist a dynamic DNS service.
Dynamic DNS Services
Dynamic DNS Services can provide a DNS server that allows you to set a name IP address that keeps up with the numeric dynamic IP address as it changes. The assigned name value with always stay the same, which simplifies dynamic IP address management.
Here’s an example of how it works. Imagine you have set up BobsHomeDVR.com on a DNS server provided by a Dynamic DSN Service provider for your dynamic IP address. Every time you type in BobsHomeDVR.com, the server will check the numeric IP address to see if it has changed, and then automatically updates it.
