[Monitoring] - IPV6 Leases

Hi all...

I´m using collectd + luci-app-statics with some monitoring modules installed and configured on my router.
I use "collectd-mod-dhcpleases" to monitor DHCP4 leases...
Is there any similar module for IPV¨? It doesn't have to be "collectd", but if it is, better?
I thought about taking the IPV4 files and creating one for IPV6, would it be very difficult to do this?
