@net = ipv6NetConvert($netAddr);
This function takes an IPv4 network address in string format and converts it into and array of arrays. The arrays will contain the base network address, the broadcast address, and the netmask, each split into native 32bit integer format chunks. Each sub array is essentially what you would get from:
@chunks = unpack 'NNNN', inet_pton(AF_INET6, '::1');
using '::1' as the sample IPv6 address.
The network address must have the netmask in CIDR format. In the case of a single IP address, the array with only have one subarray, that of the IP itself, split into 32bit integers.
Passing any argument to this function that is not a string representation of an IP address (including undef values) will cause this function to return an empty array.
@net = ipv6NetPacked('fe80::/64');
This function is a wrapper for ipv6NetConvert, but instead of subarrays each element is the packed (opaque) string as returned by inet_pton.
$rv = ipv6NetIntersect($net1, $net2);
This function tests whether an IP or subnet intersects with another IP or subnet. The return value is essentially boolean, but the true value can vary to indicate which is a subset of the other:
-1: destination range encompasses target range
0: both ranges do not intersect at all
1: target range encompasses destination range
The function handles the same string formats as ipv6NetConvert, but will allow you to test single IPs in integer format as well.
@sorted = sort ipv6StrSort @nets;
This function allows IPv6 addresses and networks to be passed in string format. Networks can be in CIDR format. Sorts in ascending order. :w
@sorted = sort ipv6PackedSort @nets;
This function sorts addresses that are in packed format, such as returned by inet_pton. Sorts in ascending order.
@sorted = sort ipv6NumSort @nets;
This function sorts addresses that are in unpacked, native integer format, such as one gets from:
@ip = unpack 'NNNN', inet_pton(AF_INET6, $ipAddr);
Sorts in ascending order. List of addresses should be a list of lists.
You can use this for validating IP addresses as such:
$ip =~ m#^@{[ IPV6REGEX ]}$#;
or to extract potential IPs from extraneous text:
@ips = ( $string =~ m#(@{[ IPV6REGEX ]})#g);
By default this will extract CIDR notation network addresses:
@networks = ( $string =~ m#(@{[ IPV6CIDRRGX ]})#si );
