10.10.10.10 is a private IPv4 address. It belongs to the block of private addresses inside class A just like all the other addresses from 10.0.0.0 to 10.255.255.255. They are called private because they are reserved for private use only and cannot be traced on the internet (not visible from outside the internet). All these addresses can be used without asking the authorities (IANA) for a permission.
Any 10.x.x.x address can be assigned to routers, modems, and other networking devices by their manufacturers. 10.10.10.10 is not as popular as 10.0.0.1, 10.0.0.138, 10.0.1.1, or 10.10.1.1 but it can be a default gateway (IP address assigned by default to your router, modem, access point, or some other networking device). It can also be one of the addresses assigned to your PC, phone, laptop, or tablet if it’s one of the available addresses inside the DHCP pool.
This address is assigned to ITUS Networks Shield Pro Firewall as a default gateway and that’s the only device that we know about with 10.10.10.10 default gateway.
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.
