Each server or client on a TCP/IP internet is identified by a numeric IP address. IP stands for Internet Protocol.
IP address in hexadecimal notation : '817EB263'x
Byte 0: 81 hexadecimal = 129 decimal
Byte 1: 7E hexadecimal = 126 decimal
Byte 2: B2 hexadecimal = 178 decimal
Byte 3: 63 hexadecimal = 99 decimal
IP address in dotted decimal notation: 129.126.178.99
A newer type of IP address, the IPv6 (IP version 6) address, is 128 bits. It is usually expressed in hexadecimal notation, and not in dotted decimal notation. (CICS® Web support does not support IPv6 addresses.)
IP addresses are managed and allocated to users by the Internet Assigned Numbers Authority (IANA) and its delegates.
