Summary

Reliable and robust operation of the DNS hierarchy - from the root servers to an individual domain name server - is critical to all Internet operations. The course covers the configuration and operation of DNS systems used for a variety of purposes from high availability Zone Masters and Slaves running mission critical sites to caching servers used to speed up Internet access. While the primary focus of the course is BIND other DNS software will be discussed. BIND supports Linux, BSD and Windows platforms - installation procedures for each platform are covered.
