An addition: here's my solution (as a regular expression):
(?:(?:(?:(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(?:(?!(?:.*[a-f0-9](?
::|$)){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?::(?:[a-f0-9]{1,4}(?
::[a-f0-9]{1,4}){0,5})?)))|(?:(?:(?:[a-f0-9]{1,4}(?::[a-f0-
9]{1,4}){5}:)|(?:(?!(?:.*[a-f0-9]:){5,})(?:[a-f0-9]{1,4}(?::[a-f0-
9]{1,4}){0,3})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}:)?))?(?:(?
:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\.(?:(?:25[0-
5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))

Description:
------------
FILTER_VALIDATE_IP validates the incorrect 0:::255.255.255.255 and does
not validate the correct 0::255.255.255.255
According to RFC 5321, the correct syntax is:
[IPv6-hex *3(":" IPv6-hex)] "::" [IPv6-hex *3(":" IPv6-hex) ":"] IPv4-
address-literal
This does not allow for three consecutive colons.
Reproduce code:
---------------
// First
filter_var('FFFF:::255.255.255.255', FILTER_VALIDATE_IP);
// Second
filter_var('FFFF::255.255.255.255', FILTER_VALIDATE_IP);
Expected result:
----------------
// First
bool(false)
// Second
string(21) 'FFFF::255.255.255.255'
Actual result:
--------------
// First
string(22) 'FFFF:::255.255.255.255'
// Second
bool(false)
