192.168.0.20 is a private IPv4 address. It’s one of the addresses from the reserved block of private addresses within Class C. All the 192.168.x.x addresses belong to this block and they are all reserved for private networks. These addresses are not routable on the internet.
Devices Using 192.168.0.20 as a Default Gateway
192.168.0.20 is not a popular choice when it comes to default gateways. Manufacturers prefer some other addresses. It’s not like other addresses are better, they are simply more popular. Still, some manufacturers like Cellvision and D-Link assign this address to their IP cameras. You can find it on devices like CAS-200W (Cellvision IP camera), DCS-5020L, DCS-1000W, DCS-930L, DCS-942L, and DCS-5222L (D-Link IP cameras).
192.168.0.20 is more often assigned to different devices connected to a home network. If your router’s default gateway is 192.168.0.1, 192.168.0.2, 192.168.0.10 or 192.168.0.254, 192.168.0.20 will probably be one of the available addresses in the DHCP pool and it can be assigned to a device connected to your home network (automatically or manually).
Assigning 192.168.0.20 Automatically (Dynamic IP)
If your router’s default gateway is one of the previously mentioned IP addresses and if 192.168.0.20 is one of the addresses inside the DHCP pool, then it can be assigned (automatically) to a device connected to your home network. The address will be assigned to your device until you disconnect it. After that, the address gets back to the DHCP pool, it becomes available again, and it can be assigned to some other device. So, when the address is assigned automatically, it doesn’t have to be assigned to the same device every time it gets connected to the network.
If you want the same IP address assigned to your device every time that device joins the network, you have to assign the address manually.
Assigning 192.168.0.20 Manually (Static IP)
When assigning some IP address manually, you have to pay attention to two things. First, you have to check if the address is inside the DHCP pool. Second, you have to check if the address is taken (if it’s already assigned to some device). If the address is already assigned to some and you assign it manually to some other device, there will be two devices with the same IP and they will be both disconnected from the network. This issue is known as IP conflict.
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.
