Synopsis

Reverse DNS allows the mapping of a domain name from an IP address. This is achieved by the use of pseudo-domain names under in-addr.arpa (IPv4) and ip6.arpa (IPv6). For all IP address blocks that IANA (the Internet Assigned Numbers Authority) allocates to APNIC, it also delegates corresponding reverse DNS zones within the centrally administered “in-addr.arpa” and “ip6.arpa” domains.

Course outline

This webinar will cover the following topics:

  • What is Reverse DNS?
  • Principles of DNS Tree
  • Creating Reverse Zones
  • Pointer (PTR) Records
  • IPv6 Reverse Lookups
  • Reverse delegation requirements
  • APNIC & ISPs responsibilities
  • Reverse Delegation Procedures
  • Whois domain object

Note: This webinar will run for approximately 60 minutes, with 15 minutes of question time.
