+If your PC gets its nameserver from a DHCP server, you will need to reconfigure dhclient.conf to make 127.0.0.1 your primary domain server.
+Here is the file you need to edit: ''/etc/dhcp3/dhclient.conf'', uncomment or add the following line ...
+   prepend domain-name-servers 127.0.0.1;
+If you got the static ip address, in this case you just need to edit your ''/etc/resov.conf'' file and add the following entries ..
+   nameserver 127.0.0.1

+===== Reverse whois lookups =====
+ If we want to check the whois info for a reverse zone, a special whois lookup is requred.
+ For example, if we have the network 212.18.32.0/24 and want to check its RIPE data, the following
+ whois query would be performed:
+<code>
+whois -h whois.ripe.net 32.18.212.in-addr.arpa
+</code>
+or\\
+<code>
+telnet whois.ripe.net 43
+.18.212.in-addr.arpa
