If your laptop is the first or second device to connect after the router restarts, the router frequently pulls .100 from its "pool" of available numbers and hands it to you. This is temporary; if you leave the house and come back, your IP might change to .101 or .102 .

If you are trying to access your router or a specific device on your network, you likely typed a variation of into your browser. This specific sequence of numbers is one of the most common private IP addresses used in home and small office networks worldwide.
More commonly, 192.168.1.100 is the first address in the DHCP (Dynamic Host Configuration Protocol) pool . Your router acts as a DHCP server, automatically assigning unique private IP addresses to every device that connects to your network (laptops, phones, printers, etc.). Many routers are configured with a DHCP range starting at 192.168.1.100 and ending at 192.168.1.200 or 192.168.1.149 . This means your computer might be assigned 192.168.1.100 , your phone 192.168.1.101 , and so on.
If two devices on your network accidentally claim the same IP, a "Default Gateway" error or "IP Address Conflict" occurs. Knowing your device is sitting at .100 helps you identify the clash.
