You have to create a zone for each /24 block of address space within
your /20 allocation. So you'll need to set up zones like
64.73.217.in-addr.arpa, 65.73.217.in-addr.arpa and so on until
79.73.217.in-addr.arpa.

After that, you'll need to create domain objects in the RIPE Database to
get delegation for these zones to your name servers. Please see the
reverse DNS howto on the RIPE NCC website at:
