NAME

Fsdb::Support::IPv6 - ipv6-parsing helpers

SYNOPSIS

use Fsdb::Support::IPv6;

ipv6_zeroize

$ipv6_zeroized = Fsdb::Support::IPv6::ipv6_zeroize('1:0002:3:4::');
# result is 1:2:3:4:0:0:0:0

Normalize an IPv6 address so it has all hextets present, with no leading zeros.

Handles any valid IPv6 address as input.

Also treats strings of hex digits without colons as IPv6 prefixes.

ipv6_fullhex

$ipv6_fullhex = Fsdb::Support::IPv6::ipv6_fullhex('1:0002:3:4::');
# result is 0001000200030004000000000000000

Rewrite an IPv6 address as a full, 128-bit, base-16 number.

ipv6_normalize

$ipv6_normal = Fsdb::Support::IPv6::ipv6_normalize('1:0002::7:0:00:8');
# result is 1:2::7:0:0:8

Convert an IPv6 address to IETF normal form. The input maybe has some fields 0 or leading zero, or :: in a non-standard place. Normalize it to remove leading zeros and replace the leftmost, longest run of zeros with ::.

We remove any mixed IPv4/v6 addresses (IPv6 addreses that end in dotted-quads).

Also treats strings of hex digits without colons as IPv6 prefixes.

ip_fullhex_to_normal

$ip_normal = Fsdb::Support::IPv6::ip_fullhex_to_normal('20010db8000300040005000600070008');
# result is 2001:db8:3:4:5:6:7:8

$ip_normal = Fsdb::Support::IPv6::ip_fullhex_to_normal('c0000201');
# result is 192.0.2.1

Convert an IPv6 address to IETF normal form. The input maybe has some fields 0 or leading zero, or :: in a non-standard place. Normalize it to remove leading zeros and replace the leftmost, longest run of zeros with ::.

Also treats strings of hex digits without colons as IPv6 prefixes.
