		+	= '''DNS - Domain Name Server''' =
		+	DNS is a system used to find computers on the internet and in private networks. The most common DNS server is the UNIX/Linux BIND8 & BIND9 NAMED(Named Daemon) package. Microsoft and other companies also make their own proprietary DNS server packages as well.
		+
		+	== '''Query DNS Server Records - Find an IP address or hostname''' ==
		+	There are a number of tools which can be used to query information from DNS servers. The two most common command-line DNS tools are DIG and NSLOOKUP.
		+
		+	=== '''DIG''' ===
		+	Dig is a simple command used to query DNS server records, either by supplying the FQDN(Fully Qualified Domain Name - such as "www.dawgland.com", into a numeric IP address, such as "73.42.198.249". This basic main IP address is known as a type A DNS server record, as it's IP version 4, which consists of 4 numbers separatedd by 3 dots. Less used currently are IPv6(IP version 6) records, known as AAAA DNS server records. Other DNS server record types are CN, which stands for "Common Name", which are aliases to actual hostnames, such as "mail" pointing to the IP address of the hostname "mail.domainname.com", and MX records,used to indicate actual email servers.
		+
		+	Here are some examples of how to use the dig command:
		+	Query a standard A hostname DNS record:
		+	<pre style="color:blue">
		+	[jamie@server.dawgland.com:~]$ dig A jrcomputers.net +short
		+	213.255.247.82
		+	[jamie@server.dawgland.com:~]$
		+	</pre>
		+	<br /><br />
		+	Query an Email Server's DNS record:
		+	<pre style="color:blue">
		+	[jamie@server.dawgland.com:~]$ dig MX jrcomputers.net +short
		+	0 mail.jrcomputers.net.
		+	[jamie@server.dawgland.com:~]$
		+	</pre>
		+	<br /><br />
		+	Perform a Reverse-DNS(rDNS) query/lookup:
		+	<pre style="color:blue">
		+	[jamie@server.dawgland.com:~]$ dig -x 213.255.247.82 +short
		+	mail.jrcomputers.net.
		+	[jamie@server.dawgland.com:~]$
		+	</pre>
		+	<br /><br />
		+
