Hello,

 

Im rusiing 4.1.13-1pdns.el7

I just noticed a lot of these lines

When debugging i see one iprange over and over and over again.

 

 

Jun  8 20:10:24 ns3 pdns_server: Remote 195.121.82.135 wants
'KS-DC-01.ksprofiel.nl|A', do = 1, bufsize = 1232: packetcache MISS

Jun  8 20:10:27 ns3 pdns_server: Remote 195.121.82.111 wants
'KS-DC-01.ksprofiel.nl|DS', do = 1, bufsize = 1232: packetcache MISS

Jun  8 20:10:27 ns3 pdns_server: Remote 195.121.82.111 wants
'KS-DC-01.ksprofiel.nl|A', do = 1, bufsize = 1232: packetcache MISS

 

Soemthimes it is a packetcache HIT (another domain)

 

Is this some kind of hakking attempt or normal ?
