[Solved] Custom block page for Custom IP or domain name

[t0ny54]

Long story short, i used dnscrypt (dns resolver, IP blocklists) <-> adguardhome (dns filter, Client settings, Parental control, etc) <-> iis manager (webserver for serving a 1x1 pixel transparent png file on port 80 & 443)

I want feature Custom block page for Custom IP or domain name, because dnscrypt don't have this feature yet.
(Look like this example https://github.com/AdguardTeam/AdGuardHome/wiki/FAQ#customblock)

Thank you

Edit:
Solved with blocked_query_response = 'a:xxx.xxx.xxx.xxx' in dnscrypt-proxy.toml
