IP Address Notation
When configuring a port interface via the CLI you must enter an IP address. The CLI always accepts an IPv4
address, and in some cases accepts an IPv6 address as an alternative.
For some configuration commands, the CLI also accepts CIDR notation. Always view the online Help for the
CLI command to verify acceptable forms of IP address notation.
IPv4 Dotted-Decimal Notation
An Internet Protocol Version 4 (IPv4) address consists of 32 bits divided into four octets. These four octets
are written in decimal numbers, ranging from 0 to 255, and are concatenated as a character string with full
stop delimiters (dots) between each number.
For example, the address of the loopback interface, usually assigned the host name localhost, is 127.0.0.1. It
consists of the four binary octets 01111111, 00000000, 00000000, and 00000001, forming the full 32-bit
address.
IPv4 allows 32 bits for an Internet Protocol address and can, therefore, support 2

are overwritten.
