@net = ipv4NetConvert($netAddr);
This function takes an IPv4 network address in string format and converts it into an array containing the base network address, the broadcast address, and the netmask, in integer format. The network address can have the netmask in either CIDR format or dotted quads.
In the case of a single IP address, the array with only have one element, that of the IP in integer format.
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.
$rv = ipv4NetIntersect($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 ipv4NetConvert, but will allow you to test single IPs in integer format as well.
@sorted = sort ipv4StrSort @nets;
This function allows IPv4 addresses and networks to be passed in string format. Networks can be in CIDR format. Sorts in ascending order.
@sorted = sort ipv4PackedSort @nets;
This function sorts IPv4 addresses as returned by inet_aton. Sorts in ascending order.
@sorted = sort ipv4NumSort @nets;
This function is rather pointless, but is included merely for completeness. Addresses are in unpacked, native integer format, such as one gets from:
$ip = unpack 'N', inet_aton($ipAddr);
You can use this for validating IP addresses as such:
$ip =~ m#^@{[ IPV4REGEX ]}$#;
or to extract potential IPs from extraneous text:
@ips = ( $string =~ m#(@{[ IPV4REGEX ]})#gsm);
By default this will test a CIDR notation or dotted quad network address:
$netaddr =~ m#@{[ IPV4CIDRRGX ]}$#s;
or extract network addresses from a string:
@networks = ( $string =~ m#(@{[ IPV4CIDRRGX ]})#s );
