Example Syntax: test.mydomain.com A RECORD 156.1.12.99

A Record Round Robin - like and standard "A Record" only a Host with Two or More IP Addresses to give multiple servers the same service request like a cluster of servers.
Example Syntax: test.mydomain.com A RECORD 156.1.12.99, 156.1.12.100, 156.1.12.101,

CNAME - (Canonical Name Record) aka an aliases of another A record host name. (RFC 1035)
Example Syntax: www.mywebsite.com CNAME my.webhostingserver.com

MX - (Mail Exchanger Record) (MX record) is a type of resource record in the Domain Name System that specifies a email server responsible for accepting email messages on behalf of a recipient's domain
priority is used to determine which servers get tried first by assigning values like 10, 20, 30, and so on. (RFC 1035)
The lowest value gets highest priority.
Example Syntax: mydomain.com MX 10 my.emailserver.com

OR Multiple Email Servers
Example Syntax: mydomain.com MX 10 my.emailserver.com
Example Syntax: mydomain.com MX 20 my.backupemailserver.com

TXT - (Text Record) Entry record was originally intended for human-readable text. (RFC 1035)
These records are dynamic and can be used for several purposes.

a common vulnerability, by verifying sender IP addresses. (RFC 4408)

SRV - (Service Locator Record) points one domain to another domain name using a specific destination port. (RFC 2782)
SRV records allow specific services, such as VOIP or IM, to be directed to a separate location.

Given an IP address of the form a.b.c.d, the usual form for a PTR record is this:
Example Syntax: 2.10.17.199.in-addr.arpa . PTR my.hostname.com. Reverse Record.
my.hostname.com A Record 199.17.10.2 Forward Record

NS - (Name Server Record) Delegates a DNS zone to use the given authoritative name servers. (RFC 1035)

---- DNS modifiers ----

TTL - (Time to live) TTL is what dictates how long it will be until your computer refreshes its DNS related information. (RFC791), (RFC1122) ?
The TTL default vaule is ( 4 hours )
