The validation rules examine an IPv6 address, looking for a maximum of 7 colons. I have encountered a specific case, when describing a /112 range, where 8 colons is legal:
e.g. 2001:db8:3:4:5:6:7::/112
Here is a proposed solution:
# Count octets
my $n = ( $ip =~ tr/:/:/ );
- return 0 unless ( $n > 0 and $n < 8 );
+ return 0 unless ( $n > 0 and $n < ( $ip =~ /::$/ ? 9 : 8 ) );
This address is legal, at least according to this utility:
