+You can use a tool called named- checkconf to check BIND dns server
     named-checkconf /etc/named.conf
-    named-checkzone

+====== DNS servers ======
+=== Unbound ===
+From: https://unbound.net/
+<code>
+Unbound is a validating, recursive, and caching DNS resolver.
+On pfSense 2.2, Unbound has been integrated into the base system. Unbound is also the default
+DNS Resolver for new installations.
+</code>
+From: https://doc.pfsense.org/index.php/Unbound_DNS_Resolver
+<code>
+Unbound is a validating, recursive, and caching DNS resolver.
+The C implementation of Unbound is developed and maintained by NLnet Labs. It is based on ideas
+and algorithms taken from a java prototype developed by Verisign labs, Nominet, Kirei and ep.net.
+Unbound is designed as a set of modular components, so that also DNSSEC (secure DNS) validation and
+stub-resolvers (that do not run as a server, but are linked into an application) are easily possible.
+The source code is under a BSD License.
+</code>
+=== PowerDNS ===
+From: https://www.powerdns.com/downloads.html
+<code>
+Both the PowerDNS Authoritative and the PowerDNS Recursive Servers are available in source form,
+as well as installable Linux Packages. PowerDNS is shipped with many Linux and UNIX distributions,
+including Debian, FreeBSD, Gentoo, NetBSD, SUSE and Ubuntu.
+Users of these distributions may find they already have a copy of PowerDNS available, often in
+the package called pdns, powerdns-server, pdns-recursor or pdns-server.

+.2: Add a zone for the local domain:
+    zone "home.lan" IN {
+        type master;
+        file "/etc/bind/zones/home.lan.db";
+    };
+.3: Also add a zone for reverse dns lookups for the local network:
+    zone "0.168.192.in-addr.arpa" {
+    type master;
+    file "/etc/bind/zones/rev.0.168.192.in-addr.arpa";
+    };
+Also: for OpenSuse 11.1
+   the default file location zone files is "/var/lib/named"
+=== Dual DHCP DNS Server ===
+From: http://dhcp-dns-server.sourceforge.net/
+    DHCP Server allots the IP addresses to computers, while DNS server resolves them.
+    You need DHCP Server if you do not want to manually maintain IP Addresses or you have less IP
+    Addresses than number of machines you have, as dynamic DHCP Server will recycle IP Addresses on
+    machines.
+    DNS Server is needed for resolving hostnames to their IP addresses. Normally your ISP will provide you
+    with DNS Service. You may have your own DNS Server, which will resolve hostnames by forwarding them to
+    ISP's DNS Server and cache the addresses also.
+    If you have home/small office network with Unix/Linux machines, these machines will not be resolved from
+    each other, as Unix/Linux machines do not support NBNS protocol and you need your own DNS Server. But how
+     about resolving your local machines ?. Your ISP's DNS Server will not have this list and your own DNS
+     Server wont have them either. Most DNS Servers cannot do this.(unless you configure dynamic updates, or
+     use static IP addresses and manually enter them).
+====== DNS at the local area network level ======
+From: http://community.spiceworks.com/topic/247882-dns-at-the-local-area-network-level
+    I start setting the first AD/DC — the angular stone for our network. After setting up the operating systemincluding updates and SPs, it was decided the machine will be hosting the domain luckyeyes.local.
+    To start, I open the network card properties/TCP IP properties, and use a static IP of 172.16.10.200
+    with network mask 255.255.255.0, the IP of the default gateway (172.16.10.254).
