denied query on bind

[ChrisC]

Hi,
Im running bind 8.2.4 on solaris 9. My messages /log files are
constantly fillling up with 'denied query' from various ip addresses
to the following

denied query from [206.222.107.70].53 for
"82.80/28.192.147.12.in-addr.arpa
" IN Sep 13 08:17:54 

The ip address looks strange and I havnt seen it before, Im trying to
find out why Im constantly getting queries for this, could someone
give me a clue??

Thanks
