Good point, sorry, I get the same list of queries for
0.111.168.192.in-addr.arpa AND for 225.177.159.10.in-addr.arpa - cut and
paste error.  I am trying to block both sets of queries

note 192.168.111.0/24 is my subnet, so I can sort of see why those
queries might exist, but I can't see why I'm getting queries in the
10.0.0.0/8 space?

I have read wikipedia and I have a rudimentary understanding of
zeroconf.  I don't understand your explanation though.  Wikipedia
confirms my limited understanding which is that bonjour is implemented
via multicast to the 224.0.0.0/8 space - I don't understand why I'm
seeing stuff in the 10.0.0.0/8 space?


Thanks
