Advanced DNS Training

Duration:1 day. This course can also be added to the Basic DNS Course to create a three day course.

La formation est aussi disponible en français.

The primary focus of the course is BIND which is available on Linux, UNIX and Windows platforms. The course is offered with Linux (Fedora Core), FreeBSD or Windows 7, 8 or 10 as the platform for all exercises.


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 administrative security, Stealth configurations, load-balancing, failover strategies, best practises and DHCP integration with DDNS. While the primary focus of the course is BIND other DNS software will be discussed.


Students will review the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. The DNS can be used for a number of purposes each of which is covered in detail: Stealth (DMZ) Configuration; Load-balancing and failover (strategies and limitations); securely auto-updating the DNS by integration with DHCP; administrative security and best-practices; SPF(TXT) RRs; Advanced Diagnostics and debugging. The course includes a number of hands on configuration exercises.


The course is designed for experienced DNS administrators, Network and System Administrators and those who need an understanding of DNS capabilities.
