DNS, DNSSEC and the Future

The key to DNS is its hierarchical nature that makes delegation so easy. It is very important to set-up and document the DNS with best practices firmly in mind or the corporate system will crumble. The aim is to mitigate the risks of mis-configuration and attack so down time is kept to a minimum or compensated for by reducing the single point of failure.
