192.168.1.104 is a class C private IPv4 address. It’s one of 65,534 private addresses from the reserved block of private IP addresses within class C (192.168.x.x IP addresses). Like all the private addresses (from this and other reserved blocks), this private address can only be used inside private networks and cannot be routed on the internet.
192.168.1.104 is also one of the addresses from a smaller 192.168.1.0/24 subnetwork. Some addresses from this block are very popular when it comes to default gateways (192.168.1.1, 192.168.1.10, 192.168.1.100, and 192.168.1.254). These addresses are assigned to modems, routers, and other networking devices by their manufacturers.
192.168.1.104 is assigned to the Ricoh copier Aficio 3224C as a default gateway and that’s the only device with this gateway. You can use this address if you want to access copier’s configuration page and change some network settings.
There’s a much greater chance to see this address assigned to some device connected to your home network if your router’s default gateway is some 192.168.1.x IP address. This address can be assigned to a device connected to your home network automatically (dynamic IP) or manually (static IP).

Assigning 192.168.1.104 Automatically
Routers assign IP addresses automatically by default. If your router’s default gateway is some 192.168.1.x address and if the DHCP pool of available address includes 192.168.1.104, this address can be assigned to some device connected to your network.
Let’s assume that your router’s default gateway is 192.168.1.100. If the DHCP pool starts at 192.168.1.101 and if the addresses are assigned in a sequential order (which is not always the case), 192.168.1.104 will be assigned to the fourth device connected to your home network.
When the address is assigned automatically, it’s not assigned permanently to your device. This address is only leased to your device for a certain period of time. When the lease time expires, the router (DHCP server) checks if your device is connected – if it is connected, the lease will be renewed and if it’s not connected, the address will become available. The address can now be assigned to some other device. That’s why all the automatically assigned addresses are called dynamic IP address.
Assigning 192.168.1.104 Manually
If you want this address permanently assigned to your device, you have to do this manually and make it static. Static IP address can’t be assigned to some other device – it’s reserved for your device and it cannot be assigned to some other device even if your device is not connected to the network. In order to make some address static, you can make a reservation in the DHCP pool or make some changes in the TCP/IPv4 settings.
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.
