Synopsis
addr [-4 | -6] { -n | -p } address
Converts an IP
address into both hexadecimal and dotted-decimal formats. The address
is expected to be well-formed. An IPv4 address must be either 8
hexadecimal digits (with optional colons delimiting octets), or 4
dotted quads of decimal digits. An IPv6 address must be either 32
hexadecimal digits (with optional colons delimiting octets), or up to
4 octets of decimal or hexadecimal digits (delimited by dots or
colons) preceded by a pair of colons and a possible prefix of several
hexadecimal octets (e.g., ab:cd::12.34.56.78).
Options
-
-4 Specifies address as an IPv4 address. This is the default.
-
-6 Specifies address as an IPv6 address.
-
-n Used when address is in hexadecimal format.
-
-p Used when address is in dotted-decimal format, or abbreviated IPv6 format.
