Puppet users - Sep 2014 - Split domain and tld from domainname

HI,


I'm facing an issue where I need to grab the tld and domain from a 
domainname no matter how many subdomains there are.


SO far I have tried regsubstr() and split() where split is getting where I 
want, but not fully yet:

$split = split("sub.sub.sub.domain.tld", '[.]')

The following gives me in any case the tld

$tld = $split[-1] 

But as split works from left to right I cannot use $split[1]

Is there any way to solve this ?

Thanks!

Matt
