Which process does dns requests?

Hello,

I got Linux boxes. (Mandriva 10.2). I noticed that the Linux machines are
doing DNS requests like crazy (see sample below).

PTR? 73.129.31.10.in-addr.arpa. (43)
PTR? 74.129.31.10.in-addr.arpa. (43)
PTR? 90.129.31.10.in-addr.arpa. (43)
PTR? 84.40.6.10.in-addr.arpa. (41)
PTR? 119.129.31.10.in-addr.arpa. (44)
PTR? 152.129.31.10.in-addr.arpa. (44)
PTR? 153.129.31.10.in-addr.arpa. (44)

I got hundreds per second.

How can I tell which process make those DNS PTR requests?
Even better, did I screw up something in my Linux conf?

Thanks for your kind support.

netstat -pna -A inet | grep :53
