• A - Host's IP address. Address record allowing a computer name to be translated into an IP address. Each computer must have this record for its IP address to be located. These names are not assigned for clients that have dynamically assigned IP addresses, but are a must for locating servers with static IP addresses.
• PTR - Host’s domain name, host identified by its IP address
• CNAME - Host’s canonical name allows additional names or aliases to be used to locate a computer.  MX - Host’s or domain’s mail exchanger.
• NS - Host’s or domain’s name server(s).
• SOA - Indicates authority for the domain (Start of Authority)
• TXT - Generic text record
• SRV - Service location record
• RP - Responsible person
• HINFO - Host information record with CPU type and operating system
• DNS, the Domain Name System, includes a database of computer names and IP addresses.
• DNS is based on the Berkeley Internet Name Domain (BIND), using the named daemon.
• Critical DNS configuration files include /etc/named.conf and the files in the /var/named directory.
• The SOA record, also known as the Start of Authority record, is the preamble to all zone files.
• CNAME is a way to assign an additional name to a computer.
• Caching-only nameservers store requests and their associated IP addresses on a computer.
• To set up a DNS server, you need a zone file with A resource records for each computer, and PTR resource records for reverse lookups.
• Every time you change DNS, remember to update the serial number in your
• zone file. Otherwise, other DNS servers don’t realize that you’ve changed anything.
