### Operating system type

Linux, Other (please mention the version in the description)

### CPU architecture

AMD64

### Installation

Docker

### Setup

On one machine

### AdGuard Home version

v0.107.11

### Description

#### What did you do?

Created a DNS rewrite for a local IP address and hostname

#### Expected result

In addition to an A record, a PTR record would be created to allow reverse lookups.

#### Actual result

No PTR record is created, lookups only work in one direction (lookup of hostname works, lookup of IP fails)

#### Screenshots (if applicable)

#### Additional information

PTR records are a vital part of network infrastructure validation and should be a part of any modern DNS configuration.
