I use ultrdns to point my domain name to my static ip. Hence, a host domain-name returns the correct ip address. However, a host ip-address returns the isp information since their PTR zone record points to host mm-vanecek.cc mm-vanecek.cc has address 66.76.121.5 host 66.76.121.5 5.121.76.66.in-addr.arpa. 43200 IN PTR cdm-66-76-121-5.htsp.cox-internet.com [admin@www admin]$ dig mm-vanecek.cc ANY ; <<>> DiG 9.2.1 <<>> mm-vanecek.cc ANY ;; ANSWER SECTION: mm-vanecek.cc. 86268 IN MX 10 mail.mm-vanecek.cc. mm-vanecek.cc. 83121 IN A 66.76.121.5 mm-vanecek.cc. 86268 IN NS udns1.ultradns.net. mm-vanecek.cc. 86268 IN NS udns2.ultradns.net. mail.mm-vanecek.cc. 86268 IN A 66.76.121.5 Two questions. 1. Why do I not run into the same reverse lookup problem? Is it because I have a static ip? 2. If I understand things correctly ... The only way host ip-address will return my domain-name is for my isp to put a PTR record in their zone definitions (which most are reluctant to do)? Any other way to get a reverse lookup to point to my domain name as opposed to the isp name? -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
