What is local static IP address? When someone talks about setting up a computer with a local static IP address, this person probably means to have a computer to use a local IP address that will not change. Static means never change.
What is a local dynamic IP address? It means a router will monitor the expiration dates of the leases of the local dynamic IP addresses which the router gave out to various computers within a network. So when a computer uses a local dynamic IP address, sometime in the future a dynamic IP address will have its lease expired. When this happens, a router will assign a new local dynamic IP address to this particular computer. This means a dynamic IP address will have to change from time to time.
The benefits of having a local static IP address is that whenever a machine within a network is acting as a server of some sort, its local IP address remains the same as always. This means if you had done a port forwarding for this particular machine, the port forwarding settings will not have to be changed. This won’t be the case if you have a machine with a local dynamic IP address, because the local dynamic IP address will change and then the port forwarding settings too have to be reset so the router will know which local machine or server of some sort of which local IP address will be able to accept the port forwarding’s data. So, it’s clear that using local IP addresses is best when you have machines that act as servers and so on. Perhaps, a Time Machine server for doing backups for a Mac?
So, what is good about using local dynamic IP addresses? The good thing about using local dynamic IP addresses is that once you set your computer to accept dynamic IP addresses in the network settings, you can move around the whole city or just about anywhere that hands out free Internet connection and not have to mess around with the network settings again. What happens is that any public place that lets you tap into their network will probably assign your computer a local dynamic IP address. Since your computer is set to accept a local dynamic IP address, you’re good to go. You know, surfing the web and so on and not having to mess around with network settings. If you’re already have your computer sets to use a local static IP address, it will be messy for you when you tap into a public Internet connection. You will have to go into your network settings and then switch from static network settings to DHCP one. After that, when you get back to your local network, you will have to re-enter all your local static IP settings into your network settings again so your computer will be able to use a local static IP address.
What if you want to have the benefit of not messing around with the network settings at all and allow the router of whatever network to do all the hard work by assigning you a local dynamic IP address whenever, and then you still keep the local static IP address settings when you get back into your local network? How are you going to do just this? Well, the answer is to reserve a local dynamic IP address. When you reserve a local dynamic IP address, this particular local reserved dynamic IP address will always be assigned to the same machine. So, in a sense, the router is always going to automatically assign a local static IP address for a particular machine. So, in this sense, using local reserved dynamic IP address retains the same benefit of using a local dynamic IP address (i.e., the router will automatically do all the dirty work and you don’t have to mess with the network settings). So, imagine this scenario. You get to a Starbucks, get a latte, turn on your computer and then it will automatically accept a local dynamic IP address from the Starbucks’ router. When you get back home, your local network will automatically assign your computer with the reserved local dynamic IP address. This scenario allows you not to have to ever mess around with network settings once you have reserved a local dynamic IP address with your router. Yet, a particular machine which you have reserved a local dynamic IP address for will have a local static IP address as this particular reserved local dynamic IP address will never change.
Just remember, when a router automatically assigns a local IP address, it’s doing its dynamic IP thing, and when you have to open up the network settings of your machine to add a static IP address manually, you’re doing static IP address thing. Having reserved a local dynamic IP address, the router will do both dynamic and static IP things for you, letting you have more free time to do whatever. Router will automatically assign a local dynamic IP address to your machine but this particular dynamic IP address will never change. Anyhow, I hope you get it.
Within the video above, you get to see me showing you how to add a local reserved dynamic IP address so you can use it as a local static IP address for your machine. Enjoy!!!
