192.168.1.108 is a class C private IPv4 address. It’s one of 65,534 addresses from the reserved block of private addresses within this class. All the 192.168.x.x addresses (192.168.0.0/16 subnetwork) belong to this block. The fact that they are all private means that they can only be used inside private networks and cannot be directly accessed from the internet.
192.168.1.108 also belongs to a smaller 192.168.1.0/24 subnetwork (there are 254 available addresses within this subnetwork). Some addresses from this subnet (192.168.1.1, 192.168.1.10, 192.168.1.100, and 192.168.1.254) are common default gateways. They are often assigned to modems and routers by their manufacturers. 192.168.1.108 doesn’t belong to this group of popular default gateways. The thing with default gateways is that manufacturers can choose any private IP address they like (from this reserved block or from other reserved blocks of private addresses) and 192.168.1.108 is not a popular choice. Still, this address is not worse than any other private IP address and can be used as a default gateway in the future if some manufacturer decides to use it.
At this moment, it’s more likely to see this IP address assigned to some device connected to a home network (or any other private network). 192.168.1.108 (just like any other private IP address) can be assigned automatically (dynamic IP) or manually (static IP).
192.168.1.108 – Automatic Assignment (Dynamic IP)
Routers are in charge of assigning IP addresses to devices connected to private networks and they do that automatically by default. In order for 192.168.1.108 to be assigned to some device automatically, it has to be one of the available IP addresses in the DHCP pool.
Let’s assume that your router’s default gateway is one of the previously mentioned IP addresses from the 192.168.1.0/24 subnetwork (192.168.1.100, for example) and that the DHCP pool includes all the addresses within the range 192.168.1.101–192.168.1.200. This range includes 192.168.1.108 which means that it can be assigned to some device connected to your home network. If the addresses are assigned sequentially (which is not the rule), 192.168.1.108 will be assigned to the 8th device connected to your home network.
If the address is automatically assigned to some device, it is not permanently tied to it. It is only leased to that device for a certain period of time (lease time). The address will stay assigned to that device until it disconnects from the network and the lease time expires. After the lease time expires, the DHCP server (router) checks if the device is connected. If it is connected, the lease will be renewed. If it’s not connected, the address becomes available again and it can be assigned to some other device. That’s why all the automatically assigned (obtained) addresses are considered dynamic IP addresses.
192.168.1.108 – Manual Assignment (Static IP)
If you want this IP address permanently assigned to your PC, printer, camera, or any other device, you have to assign it manually and make it static. That way, you will make 192.168.1.108 unavailable for all the other devices – the address won’t be assigned to some other device even if your device is not connected to the network. In order to assign a static IP to some device, you have to reserve the address in the DHCP pool (through router’s configuration page) or to make some adjustments in the TCP/IPv4 settings on your computer.
Hello, I am Anthony Stuart…
I am writer and editor at RouterInstructions. I’ve been working as a network specialist for various employers for almost 15 years. In my lifetime, I have installed thousands of routers, modems, bridges, switches, etc. My job also includes designing, monitoring, and maintaining local area networks (LANs) as well as wide area networks (WANs). I want to share my knowledge and experience with you and help you understand the basics of IP addressing. I am also going to write about routers, network security, and other network-related topics.
