10.0.0.100 is a private IPv4 address. It belongs to the block of private addresses within class A. All the addresses starting from 10.0.0.0 to 10.255.255.255 are part of this block. The fact that this address is private means that it’s used inside private networks only and that it can’t be routed on the internet. 10.0.0.100 can be assigned to a wi-fi router as a default gateway (this is done by the router manufacturers) but it can also be assigned to any device (PC, smartphone, media player, etc.) connected to your home wi-fi network. Some other addresses from this block (10.0.0.1 and 10.0.0.2) are much more popular than 10.0.0.100 when it comes to default gateways – it’s more likely that this IP address will be assigned to a device connected to your home wi-fi network if your router’s default gateway address is one of those previously mentioned class A addresses (10.0.0.1, 10.0.0.2) and if 10.0.0.100 is one of the available addresses inside the DHCP pool. 10.0.0.100 can be assigned automatically (dynamic IP address) or manually (static IP address).

Automatic Assignment
So, if your router’s default gateway is 10.0.0.1 and if the DHCP pool includes this IP address (for example, 10.0.0.2-10.0.0.102) this address can be automatically assigned to a device connected to your wi-fi network. If the addresses are assigned in a sequential order, there’s a small chance that 10.0.0.100 will be assigned to any device (since there’s practically no chance that you have 100 devices connected to your home network simultaneously). But, if the addresses are assigned randomly, it can be assigned to your PC, laptop, or any other device.
Manual Assignment
If 10.0.0.100 is inside the DHCP pool, you can always assign it to your device manually as a static IP. In order to assign a static IP address to your device, you will have to make a reservation in the DHCP pool (in order to avoid automatic assignment of this address to some other device) or you can adjust the TCP/IPV4 settings.
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.
