So if you configure Nginx to load balance port 53 for both protocols, you could use Nginx as a load balancer for DNS.</div><div class=""><br class=""></div><div class="">However, Nginx doesn’t understand the DNS protocol. It is a layer 4 LB, not a (dns-protocol aware) L7 LB. </div><div class=""><br class=""></div><div class="">What do you want to achieve?
