SUBROUTINES/METHODS

ipInNetwork

   $rv = ipInNetwork($ip, @networks);
 
 

This function checks the passed IP against each of the networks or IPs in the list and returns true if there's a match. The list of networks can be either individual IP address or network addresses in CIDR notation or with full netmasks:

   @networks = qw(127.0.0.1 
                  192.168.0.0/24 
                  172.16.12.0/255.255.240.0);
 
 

hostInDomain

   $rv = hostInDomain($host, @domains);
 
 

This function checks the passed hostname (fully qualified) against each of the domains in the list and returns true if there's a match. None of the domains should have the preceding '.' (i.e., 'foo.com' rather than '.foo.com').
