### The problem

The local network supports both IPv4 and IPv6 dual-stack networking. However, due to the lack of support for IPv6 from network operators and other service providers, slow access and disconnections frequently occur. Therefore, AdGuardHome DNS settings disable IPv6 resolution.

However, some services only enable IPv6 and not IPv4. In these cases, DNS resolution fails. Even after entering the IPv6 address for the domain in DNS rewriting, only an invalid IPv4 address is returned, not an IPv6 one. Is it possible to improve the DNS rewriting level so that even if the user has disabled IPv6 resolution, the DNS rewriting process still returns an IPv6 address to the client? Additionally, is it possible to allow batch input of IP addresses for DNS rewriting, allowing multiple IP addresses to be entered for a single domain name?
