Share a snapshot of this report
A live report changes with every lookup, so a shared link to it would not show what you see now. A snapshot stores this report as our server observed it and gives it its own link for 30 days. It holds public lookup data only. Anyone with the link can open it; search engines are asked not to index it.
For a server that sends mail, every sending address should have one PTR name, and that name should resolve back to the address. For a website behind shared hosting or a CDN, a provider name here is normal.

What reverse DNS is
Ordinary DNS turns a name into an address. Reverse DNS goes the other way: for 192.0.2.10 a resolver asks for the PTR record of 10.2.0.192.in-addr.arpa, and for IPv6 for a name built from the 32 hex digits of the address under ip6.arpa. The PTR record is controlled by whoever holds the address block, usually the hosting provider or ISP, not by the owner of the domain. You set it in the provider's control panel or by asking them.
