#22, Reverse DNS Добавить связанный Изменить Удалить

A lookup that asks which hostname is associated with an IP address.

How reverse DNS works

Reverse DNS uses a PTR record to map an IP address back to a hostname, which may describe a provider, server, gateway, or customer connection.

The owner of the address range controls this record. It may be absent, generic, or outdated, so it is a contextual network clue rather than proof of location or proxy use.
