A Puppet function to determine if an IPv4 address is within the IPv4 CIDR
ip_in_range returns true if the ipaddress is within the given CIDRs
usage: ip_in_range(<IPv4 Address>, <IPv4 CIDR>)
or when you want to check against more than one CIDR and return true if the IP address is contained in any of them.
$ranges = ['192.168.0.0/24', '10.10.10.0/24']
$valid_ip = ip_in_range('10.10.10.53', $ranges) # $valid_ip == true
There are a couple of commonly used patterns -
$valid_ip = ip_in_range('10.10.10.53', '10.10.10.0/24') # $valid_ip == true
or using the check as part of a conditional -
if ip_in_range($ipaddress, '10.10.200.0/24') == true {
notify { 'Do subnet based resources here': }
}
It has a dependency on puppetlabs-stdlib to work.
