Internet won't query your DNS for the reverse zone. For your ip, the reverse delegation is with rr, not you, and there is a PTR record: Mgw1# dig -x 66.26.7.34 ; <<>> DiG 8.3 <<>> -x ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUERY SECTION: ;; 34.7.26.66.in-addr.arpa, type = ANY, class = IN ;; ANSWER SECTION: 34.7.26.66.in-addr.arpa. 1H IN PTR ilm26-7-034.ec.rr.com. ;; AUTHORITY SECTION: 7.26.66.in-addr.arpa. 1H IN NS ns1.ec.rr.com. 7.26.66.in-addr.arpa. 1H IN NS ns2.ec.rr.com. ;; ADDITIONAL SECTION: ns1.ec.rr.com. 1H IN A 24.93.67.126 ns2.ec.rr.com. 1H IN A 24.93.67.127 >Second, why is the 0.0.127 zone " >IN-ADDR.ARPA" capitalized where the others arent?
