Discard custom IP range results based on IP-CIDR

The problem

My IPv4 and IPv6 are from two different operators. Typically, IPv6 is better but there are some exceptions.

For specific IPv6 CIDR Ranges such as 2001:41b8::/32, 2a04:4e42::/32, etc. My IPv6 network is worse than IPv4 in QoS and speed (some times 10x slower in speed or latency) for certain domains in my network. Thus I want to exclude DNS results whose AAAA is in this range.

For example, if example.com has a A record to 1.2.3.4 and AAAA record to 2001:41b8::313, when Chrome queries, AdGuard could only return 1.2.3.4. (Do not let Chrome "know" AAAA results since I want to exclude this specific IP/CIDR range for AAAA.)

Proposed solution

Provide a special field such as ip_cidr_exclusion for users to exclude specific IP/CIDRs when DNS queries.

For example, if example.org resolves to 1.2.3.4 and 5.6.7.8 and I exclude 5.6.7.8/32, then Chrome would only know 1.2.3.4.

Alternatives considered and additional information

I read the docs and discussions; it seems that this feature does not exist. I apologize for my any possible mistakes.
