Why Are Addresses Like 192.168.100.2 So Unique?
Addresses like 192.168.100.2 are unique in the sense that they are part of the private IP address range.

The use of private IP addresses like 192.168.100.2 helps conserve the limited number of public IP addresses available and adds a layer of security since these addresses are not accessible from outside the local network. They are ideal for home and office environments where multiple devices need to communicate internally without the need for a unique public IP address for each device.
