How to redirect requests to nginx in Ap-hotspot?

Question

Nginx

I installed Ap-hotspot on ubuntu and distribute wifi through it. I want all requests to sites to go first to my nginx server.
If you put your bind9 DNS server, then all external requests will go to nginx, and I only need those via wifi.

Answer 1

If a separate subnet is allocated for wifi, then in bind you can set up different views for different addresses and, accordingly, give different answers to different views.
Google it bind9 split dns.
