Class: Requests_IPv6  - X-Ref

Class to validate and to work with IPv6 addresses

This was originally based on the PEAR class of the same name, but has been
entirely rewritten.

uncompress($ip)   X-Ref
Uncompresses an IPv6 address

RFC 4291 allows you to compress consecutive zero pieces in an address to
'::'. This method expects a valid IPv6 address and expands the '::' to
the required number of zero pieces.

Example:  FF01::101   ->  FF01:0:0:0:0:0:0:101
::1         ->  0:0:0:0:0:0:0:1

return: string The uncompressed IPv6 address
param: string $ip An IPv6 address

compress($ip)   X-Ref
Compresses an IPv6 address

RFC 4291 allows you to compress consecutive zero pieces in an address to
'::'. This method expects a valid IPv6 address and compresses consecutive
zero pieces to '::'.

Example:  FF01:0:0:0:0:0:0:101   ->  FF01::101
0:0:0:0:0:0:0:1        ->  ::1

return: string The compressed IPv6 address
param: string $ip An IPv6 address

split_v6_v4($ip)   X-Ref
Splits an IPv6 address into the IPv6 and IPv4 representation parts

RFC 4291 allows you to represent the last two parts of an IPv6 address
using the standard IPv4 representation

Example:  0:0:0:0:0:0:13.1.68.3
0:0:0:0:0:FFFF:129.144.52.38

return: string[] [0] contains the IPv6 represented part, and [1] the IPv4 represented part
param: string $ip An IPv6 address

check_ipv6($ip)   X-Ref
Checks an IPv6 address

Checks if the given IP is a valid IPv6 address

return: bool true if $ip is a valid IPv6 address
param: string $ip An IPv6 address
