Reliable, robust and secure operation of the DNS hierarchy - from the root servers to an individual domain name server - is critical to all Internet operations. The courses offered provide a range of training from novice through to established DNS professionals who need to brush up their skills or require specilased knowledge such as DNSSEC or Telephony. Courses are offered in both BIND and Windows DNS and can be delived on either a Linux/UNIX (BIND courses only) or Windows (BIND or Windows DNS courses) platform
| Course | Overview |
| Basic DNS | Basic DNS is a 2 day course but may be combined with Advanced DNS to create a 3 day course. BIND specific. Students will learn the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. The major Zone file Resource Records (SOA, NS, MX, CNAME, A, PTR, TXT, SRV and NAPTR) are described and explained in detail. A number of DNS types are introduced - including Master/Slave, Caching Only, Authoritative Only, Forwarding and Stealth - and the detailed zone files and BIND configuration files (named.conf) to control operational behavior are presented. Dynamic DNS, (DDNS), integration with DHCP, Zone Transfer, Diagnostic tools and simple security models are also covered. The course includes a number of hands on configuration exercises. |
| Advanced DNS | Advanced DNS is a 1 day course but may be combined with Basic DNS to create a 3 day course. BIND specific. 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. |
| DNS Security | DNS Security is a 2 day course. BIND specific. Students will review the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. DNS (DNSSEC) security is based on modern cryptographic techniques and processes. The student will learn the underlying principles without requiring mathematical knowledge. Specific implementation of shared-secret (symmetric) and public-key (asymmetric) implementations will be detailed covering Zone Transfer, Dynamic DNS (DDNS) and Zone Integrity. Secure DDNS integration with DHCP is covered and procedurea nd requirements for key management and key-rollover are illustrated. The course includes a number of hands on configuration exercises. |
| DNS and VoIP | DNS and Telephony (VoIP) is a 1 day course. BIND specific. Students will review the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. The major Zone file Resource Records (SOA, NS, MX, CNAME, A, AAAA, PTR, TXT, SRV and NAPTR) are described and explained in detail with reference to their uses in SIP, H.323 and ENUM applications. The course includes a number of hands on configuration exercises. |
| DNS and IPv6 | DNS and IPv6 is a 1 day course. BIND specific. Students will review the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. The course covers IPv6 forward mapping (AAAA RR) and reverse mapping using the PTR RRs. While the current IETF recommendation uses AAAA and PTR - the experimental A6 and DNAME RRs will be covered since they contain important principles. Dynamic DNS (DDNS), secure integration with DHCPv6, diagnostic tools and security models are also covered. The course includes a number of hands-on configuration exercises. |
| DNS on Windows | DNS on Windows is a 2 day course and deals exclusively with Windows native DNS implementation. |
