2 DNS servers dont work in 1 domain
Hello, I have a problem setting up local DNS servers. I'm trying to set up a master and slave for the same domain for a more fault tolerant system, and when I put both servers in /etc/resolv.conf, if the master goes down, the slave is responsible for a recursion error. But if I enter only one server's IP address everything works correctly, but I need it so that if one of the servers crashes the other one can continue to do the job
;; communications error to 192.168.1.1#53: timed out ;; Got recursion not available from 192.168.1.1, trying next server
