Why does it take some time to propagate your DNS changes? Why did the world move to Ipv6? How to secure your systems from DNS Vulnerabilities? By the end of this course, you will you will have a strong foundation on how DNS works and you can start boring your friends by talking all about it :)

Why attend?

At the end of this course, participants will be familiar with the Domain Name System and Security Extensions to the Domain Name System (DNSSEC). The course is taught “hands-on” in a virtualised FreeBSD environment using the BIND, NSD and Unbound name server implementations. Participants will configure authoritative and recursive domain name servers and will learn to analyse and debug common misconfigurations and bugs. Who knows, this could be your way to a DNS admin job!

Who is it for?

Participants should be familiar with Unix-style operating systems. The course is taught on FreeBSD but the environment will be familiar to people with a systems administration background on Linux or Solaris. The virtualised lab environment is hosted on a server in Germany.
