By specifying an other subnet as a second argument, if the second subnet include
the first you can have the rank of the first subnet in the second ::
# The rank of the ip in the subnet (the ip is the 36870nth /32 of the subnet)
# {{ address | ipsubnet(subnet) }}

If the secound subnet doesn't include the first it raise an error
You can use ``ipsubnet()`` filter with ``ipaddr()`` filter to for example split
given ``/48`` prefix into smaller, ``/64`` subnets::
