In one company environment They have 2 DNS servers in the network. One of them holds records with public IP addresses and the other DNs holds records with private IP addresses.
they use one firewall facing Internet and it also does the translation One Record-To- One Record between the DNS that holds the Records with public IPs and the DNS that holds records with private IPs.
I would like to know if this is called DMZ? or the DMZ is if they had the DNS with public IPs sitting between 2 firewalls? What is the difference?
