Not a real IT guy, but, will share my thoughts on this.
My website has a real static IP address provided by godaddy. My ISP provides a dynamic IP address, but, it never seems to change. On my local network, the CISCO router I use calls the process IP & MAC binding, but, refers to it as a ‘Static IPv4 Address’ in the IP & MAC Binding Table. The setup instructions for my Synology NAS suggests it be assigned a static IP address on my local network.
As someone alluded to in a previous post, part of the problem with the term ‘static IP address’ being used on a home network, or even a small office network, can be attributed to the various vendors & their setup instructions (assuming they are read). By the way, with plug & play devices it’s rarely necessary to read the installation instructions. Then all of a sudden, something has mysteriously ceased to function because two devices are trying to use the same internal IP address.
As a matter of practice, I try to reserve the internal IP address on any device I install on my local network so it is on the IP & MAC Binding Table. The only expense associated with this is the time it takes. I believe this is a good practice, especially with all the wireless plug and play devices available. By the way, if your wireless device is not on that table, you can only use ‘guest’ portion of my LAN which is isolated from the rest. Sort of paranoid about security!
To me it’s real easy for the users not familiar with ‘IT speak’ to refer to something with technically incorrect terms. After all, in the IT world the 1st place for something is almost always labeled a ‘0’ instead of ‘1’.
