Most operating systems let you specify an IP address as an integer as opposed to the traditional dotted-quad format.

The following IP addresses should be used for private networks: The IP address can be statically assigned to a NIC through system specific configuration, or dynamically assigned using DHCP or APIPA. One machine can have a lot of IP addresses, as a machine can have more than one NIC, and a NIC can have more than one IP address (however, that's not widely used). Every NIC used to communicate through IP, must have at least one IP address. The IP address is typically used to address a single network interface card ( NIC).

The IP address, something like 192.168.0.10, is used to address an IP endpoint.
