Why is it not redirecting to my site in bind dns?

Question

Domain Name System

I have my own server on it, several sites have been raised, I also set up my dns in the zone file, I registered it, I
site.ru CNAME 192.168.56.10
restarted the server, I specified my dns in the network settings, but when I enter it, it’s not my site that opens, but someone else’s, how can I make mine open?
PS Please do not talk about hosts, the question is about BIND.

Answer 1

Does ping site.ru
resolve correctly?

Answer 2

This is bind , not hosts.
Configure bind to serve the site.ru zone
