192.168.1.9 is a private IPv4 address. It’s one of the addresses from the reserved block of private addresses within Class C. All the addresses from 192.168.0.0/16 subnetwork belong to this block. They are all reserved for private networks and they are not accessible from outside the network.
Any private IP address can be assigned to a networking device by its manufacturer. If the address is assigned to a router, modem, or any other networking device by the manufacturer, it’s called the default gateway address. There’s nothing special about default gateway IP addresses – any private IP address can be used as a default gateway. Some addresses are simply more popular than others and 192.168.1.9 is not a popular choice when it comes to default gateways.
On the other side, if your router’s default gateway is 192.168.1.1 or 192.168.1.254, 192.168.1.9 could easily be one of the available addresses in the DHCP pool and could be assigned to your PC or any other device that joins the network.
192.168.1.9 – Automatic Assignment (Dynamic IP)
Let’s assume that your router’s default gateway is 192.168.1.1. Your DHCP pool could be defined in many different ways but it usually starts with the next available address. In this case, that’s 192.168.1.2. If you don’t make any changes regarding the DHCP pool and if the addresses are assigned in a sequential order (and they usually are), this address will be automatically assigned as a dynamic IP address to the eighth device that joins the network. When you disconnect this device and when the DHCP lease time expires, the IP address gets back to the DHCP pool and it will be assigned to the next device that joins the network. That’s why this type of address is called dynamic. If you want this address permanently assigned to a specific device, you will have to assign it manually as a static IP.
192.168.1.9 – Manual Assignment (Static IP)
If you want to assign this or any other private IP address to a specific device, you can make a DHCP reservation or enter the desired IP address manually in TCP/IPV4 settings. The procedure is quite simple and quick but you have to be careful. Before assigning an IP address manually to your device, check if the address is inside the DHCP pool and check if it’s already taken. Don’t assign this address to your device if it’s already assigned to some other device. That way, you will cause an IP conflict and both devices will be disconnected from the network.
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.
