10.10.10.1 is a private IPv4 address. It’s one of the addresses from the block of private addresses within class A. All the 10.x.x.x addresses belong to this block. These addresses are reserved for private use and can’t be routed on the internet. You don’t have to ask the IP authorities (IANA) for permission if you want to use any private IP address.
This address can be your router’s/modem’s default gateway or it can be assigned to some of your devices depending on the range of available addresses in DHCP pool.
10.10.10.1 is not really popular among manufacturers and only Cisco assigns this address to some routers and access points (1801, 1841, 877W, 857. Aironet 1200). You can always assign this address manually to your router but we don’t recommend doing that because you would have to change a bunch of other settings, too.
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.
