I have been watching the dnsmasq logs for the past couple of days and  
founds the following lines:

Apr 20 11:54:01 dnsmasq[11788]: cached 82.160.33.10 is <NODATA>-IPv4
Apr 20 11:54:04 dnsmasq[11788]: query[PTR] 10.33.160.82.in-addr.arpa  
from 192.168.0.34
Apr 20 11:54:04 dnsmasq[11788]: cached 82.160.33.10 is <NODATA>-IPv4
Apr 20 11:54:08 dnsmasq[11788]: query[PTR] 10.33.160.82.in-addr.arpa

from 192.168.0.34

the day before it was:

Apr 19 20:49:42 dnsmasq[20313]: cached 58.215.240.84 is <NXDOMAIN>-IPv4
Apr 19 20:49:46 dnsmasq[20313]: query[PTR] 84.240.215.58.in-addr.arpa  
from 192.168.0.34
Apr 19 20:49:46 dnsmasq[20313]: cached 58.215.240.84 is <NXDOMAIN>-IPv4
Apr 19 20:49:51 dnsmasq[20313]: query[PTR] 84.240.215.58.in-addr.arpa  
from 192.168.0.34

and before that it was;

Apr 19 03:11:54 dnsmasq[14684]: query[PTR] 210.87.28.218.in-addr.arpa  
from 192.168.0.34

Apr 19 03:11:54 dnsmasq[14684]: query[A] pc0.zz.ha.cn from 192.168.0.34
Apr 19 03:11:54 dnsmasq[14684]: cached pc0.zz.ha.cn is 202.102.224.0
Apr 19 03:12:00 dnsmasq[14684]: query[PTR] 210.87.28.218.in-addr.arpa  
from 192.168.0.34
Apr 19 03:12:00 dnsmasq[14684]: cached 218.28.87.210 is pc0.zz.ha.cn
Apr 19 03:12:00 dnsmasq[14684]: query[A] pc0.zz.ha.cn from 192.168.0.34
Apr 19 03:12:00 dnsmasq[14684]: cached pc0.zz.ha.cn is 202.102.224.0


Every 3-5 seconds, this went on for 12 hours or more. I didn't see  
anything that would cause this to start.  Anyone see this before? Why  
is it checking cache continuously?

Thank you

Philippe
