Ask HN: Where to buy Reverse DNS lookup database from?
- tony-allan 9y agoYou can look it up yourself, but watch out for CDN's and other third-party services and be aware that not every IP address has a reverse DNS entry. On MacOS: --------------------------------------------- Note that the IP address bytes are reversed in the following command to lookup 18.9.25.15 host -a 15.25.9.18.in-addr.arpa ;; ANSWER SECTION: 15.25.9.18.in-addr.arpa. 1800 IN PTR dmz-mailsec-scanner-4.mit.edu. --------------------------------------------- host -a dmz-mailsec-scanner-4.mit.edu ;; ANSWER SECTION: dmz-mailsec-scanner-4.mit.edu. 1800 IN A 18.9.25.15 dmz-mailsec-scanner-4.mit.edu. 1800 IN HINFO "VMWARE/VM" "LINUX"
