The IP address 192.168.1.100 is the starting point of the dynamic range for a home network router. All computer and devices on the network will correspond with this address via the Dynamic Host Configuration Protocol (DHCP). Using dynamic addresses allows each device to have its own IP address each time it connects to the Internet through the router.
Using a combination of dynamic and static IP addresses is also supported. Utilizing dynamic addresses keeps the network simple and provides tracking of all 192.168.1.100 addresses, eliminating the need for administrative oversight. Adding desktop computers, laptops, smartphones and tablets is possible without requiring a unique IP address for the entire network.
The router’s DHCP range can be changed by making adjustments to its configuration. This allows the user to decide whether or not to use 192.168.1.100, as it is a private IP address that is assigned to a computer or device on the home network. To avoid conflicts, IP addresses that are within the DHCP range of the router should not be used as static IPs.
After configuring a router, it is important to secure it with a proper password to allow only approved computers and devices to connect to the network.
