An IP address is a 32-bit binary number that uniquely identifies a particular computer on the Internet or internal network. Because binary numbers are hard to read, IP addresses are given in a dotted-quad formal of decimal numbers, each part representing 8 bits of the 32-bit address (for example, 127.0.0.1). Servers are traditionally configured to use a statically assigned IP address whereas normal PCs and other devices are dynamically allocated an IP address by a DHCP server (Dynamic Host Configuration Protocol).
