Dns slave server not updating
Users take advantage of this when they recite meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates them.
BIND (pronounced /ˈbaɪnd/), or named (/ˈneɪmdiː/), was as of 2004 the most commonly used Domain Name System (DNS) server on the Internet, and still proclaims itself to be so.
All the services start up fine on all 3 servers, but zones and info is not being replicated.
The 3 servers are tentatively installed on a Xen virtual server for testing purposes.
Configure a DNS slave server with BIND It is a good idea, to have slave server in case your master server is not reachable at any time.
Both master and slave need to defined as your DNS servers in your domain registrar, you may define more than just two server, and that is a good idea, it is also a good idea, to have your DNS server on different networks, I mean, if you have them on the same office/Data center, and that place loose Internet connectivity all your server will be out of reach, and you will loose traffic or emails or both.

Let's keep an alphabetical order for the distributions covered here: Note: You may want to save a copy of every file you will edit before doing so, in case you screw things up.
Because of this, World Wide Web (WWW) hyperlinks and Internet contact information can remain consistent and constant even if the current Internet routing arrangements change or the participant uses a mobile device.
Internet domain names are easier to remember than IP addresses such as 2.166 (IPv4) or 2001:db8:1f70::999:de48:6e8 (IPv6).
Most importantly, it translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.
The Domain Name System makes it possible to assign domain names to groups of Internet resources and users in a meaningful way, independent of each entity's physical location.
