As with all networking software, the DNS facility can experience more or less severe kinds of exposures that allow an attacker to get a deeper insight and better understanding of the server's internals. A DNS server carries descriptive information like hostnames, subdomain names, and IP addresses for at least one network. If an attacker has that information, she or he will be able to think about your network carefully before launching an attack. A system administrator must, therefore, avoid any information leakage on a network's DNS servers.
