01:05 - What is DNS?
The Domain Name System (DNS) is a name resolution service. DNS resolves human-friendly addresses (such as
www.armourinfosec.com) into IP addresses (such as 192.168.1.1).
02:28 - Types of DNS Server ?
o Authoritative Servers (Responsible to give reliable answers for a certain zones)
Master (Primary)
Slave (Secondary)-Normally required 2 secondary Name Servers.
o Caching/Recursive Server
03:38 - DNS Records
A - Address Mapping records
The record A specifies IP address (IPv4) for given host.
AAAA - IP Version 6 Address records
The record AAAA (also quad-A record) specifies IPv6 address for given host.
CNAME - Canonical Name records
The CNAME record specifies a domain name that has to be queried in order to resolve the original DNS query.
NS - Name Server records
The NS record specifies an authoritative name server for given host.
PTR - Reverse-lookup Pointer records
As opposed to forward DNS resolution (A and AAAA DNS records)
SOA - Start of Authority records
The record specifies core information about a DNS zone
HINFO - Host Information records
HINFO records are used to acquire general information about a host. The record specifies type of CPU and OS.
MX - Mail exchanger record
The MX resource record specifies a mail exchange server for a DNS domain name.
TXT - Text records
The text record can hold arbitrary non-formatted
