It works fine for me.

Notice that DiG sends an ANY query, not a PTR query.  An ANY query will
simply return the alias, not follow it.

ns.drake-networks.de includes the following NS records in their zone:

64-27.47.224.212.in-addr.arpa.  4H IN NS  ns.easynet.net.
64-27.47.224.212.in-addr.arpa.  4H IN NS  ns.easybone.net.
64-27.47.224.212.in-addr.arpa.  4H IN NS  ns.drake-network.de.

However, neither ns.easynet.net nor ns.easybone.net appear to have the zone
loaded.  They seem to be expecting you to be a slave for this zone (it's
always a good idea to have multiple nameservers for a zone).
