Hello i want to return custom ip for Nx Domains (non exists domains). any one know how to do this?

Create A Conditional Forward zone for "." and tick use this server and disable DNSSEC for this zone. Then create a "*" A Record and point to the IP of the desired custom IP.

Actually I just tested this and it does not work. Sorry.

Thanks for the post. There is no option to do that. Can you let me know the use-case for such a requirement so that I can understand it better to decide on implementing such an option.

i have a v2ray vpn server ( i dont know you heard of this protocol) and its designed to bypass censorship. any way i have routed multiple servers with this and i used the dns server in highest level server. the response dns server is return for nx domain servers cannot be read and filtered in v2ray and i just to change this empty value to something like 127.0.0.1 to block all nxdomains in first level. thats all

Thanks for the description but its still not clear to me. Why do you want to block NXDOMAIN response when it just means that the domain does not exists and thus there is nothing to block?
