192.168.1.11 is a private IPv4 address. It’s one of 65,534 addresses from the reserved block of private addresses inside class C. All the addresses from the 192.168.0.0/16 subnetwork belong to this reserved block. Private addresses can only be used inside private networks and can’t be routed on the internet.
192.168.1.11 is also one of the private addresses that belong to a smaller 192.168.1.0/24 subnetwork. Some addresses from this subnetwork (192.168.1.1, 192.168.1.10, 192.168.1.100, and 192.168.1.254) are often used by router and modem manufacturers as default gateways.
192.168.1.11 is not as popular as those previously mentioned addresses but the manufacturer called ZyXEL uses this address and assigns it to its wireless Ethernet adapter and bridge ZyAIR B-420. If you have this adapter/bridge, you can use this address to access the device’s web configurator and adjust some network and security settings. You just have to type in this address in your web browser and press Enter.
It’s more likely to see this address assigned to some device connected to your home network or some other private network. 192.168.1.11 can be assigned automatically (as a dynamic IP) or manually (as a static IP).
192.168.1.11 as a Dynamic IP Address
If 192.168.1.11 is one of the available addresses in the DHCP pool, it can be assigned to some device by the DHCP server (your router) automatically. The automatic assignment is the default assigning method.
If your router’s default gateway is one of those previously mentioned popular gateways from the 192.168.1.0/24 subnetwork (for example, 192.168.1.1 or 192.168.1.10), and if the range of available IP addresses spans from 192.168.1.11 to 192.168.1.100, the address from our title will be one of the available addresses. Even if it’s not inside the DHCP pool, you can always extend the pool by making a small change in the DHCP settings (router’s configuration page). So, if the range starts with this address and if the addresses are assigned sequentially (which is not always the case), 192.168.1.11 will be assigned to the first device connected to your home network.
If an IP address is assigned automatically to a certain device, it won’t stay assigned to that same device forever. The automatically assigned IP address is only leased to that device for a certain period of time (lease time). When the lease time expires, the router checks if the device is still connected. If the device is connected, the lease gets renewed. If the device is not connected, the address becomes available again and can be assigned to some other device. That’s why all the automatically assigned addresses are called dynamic IP addresses.
192.168.1.11 as a Static IP Address
If you want this address permanently tied to your device, you have to assign it manually as a static IP. When the address is assigned manually, it cannot be assigned to some other device even if your device is not connected. The address is marked as unavailable at all times. In order to assign this address (or any other private IP address) manually to your device, you have to make a reservation in the DHCP pool (through the 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.
