Hi All, I started toying around with O'Reilly's DNS and Bind book today, but I'm having some minor problems with my rDNS. I can forward lookup using nslookup, but my reverse lookup doesn't seem to work. Hope somebody could point it out. Forward lookup Code: [root@ns2 var]#nslookup orange Server: 127.0.0.1 Address: 127.0.0.1#53 Name: orange.real-websolutions.net Address: MY IP Reverse Lookup Code: [root@ns2 var]#nslookup MY IP Server: 127.0.0.1 Address: 127.0.0.1#53 *** Can't find MY IP rDNS.in-addr.arpa.: No answer I've also added txt files from: /etc/resolv.conf /etc/named.conf /var/named/db.127.0. /var/named/db.My IP rDNS Hoping someone can point me in the right direction!
