The problem

Currently, DNS responses created using $dnsrewrite rules in AdGuardHome always use the blocked_response_ttl value defined in the configuration, regardless of the type of response being returned.

Proposed solution

It would be useful if AdGuardHome supported a TTL modifier in DNS filtering rules, allowing users to set a custom TTL (Time To Live) for responses created using $dnsrewrite=. For example, a rule like ||example.com^$dnsrewrite=NOERROR,ttl=3600;A;192.168.1.100 would return a record with a 1-hour TTL. This would give users more control over DNS caching behavior, especially in cases where shorter or longer TTLs are desired for custom or overridden records.
