Reverse DNS query - PTR records ..
Posted on 2008-10-04
My linux box has two interfaces eth0 and eth1 configured with 10.232.19.100 and 192.168.1.1 respectively .
But as soon as the box is restarted , the box send reverse dns query (PTR ) to nameserver defined in /etc/resolv.conf file .
1. why this reverse dns query is sent out ? Can i assign any name to these interfaces so that it wont query a PTR records .
i defined entries in /etc/hosts file for eth0 and eth1 , and defined /etc/host.conf . But still it sends out reverse dns query .
2 . Why it is not picking entries from /etc/hosts file .
3 . There is a reverse dns query for 192.168.1.0 also . WHy it is so ?
