2.1.1 IP address (version 4)
The IP addresses consist of 4 bytes. These 4 bytes are written in decimal
notation, separated by a decimal point.
Since 1992, five classes of IP address have been defined in the RFC 1340.
The network address represents the fixed part of the IP address. The
worldwide leading regulatory board for assigning Internet addresses is the
IANA (Internet Assigned Numbers Authority). If you need an IP address
block, contact your Internet-Service-Provider. Internet Service Providers
should contact their local higher-level organization:
