Having a thorough understanding of the topics presented here is important to both the exam and on-the-job success.
Each machine on a computer network is assigned a unique network address.
To solve this dilemma, a system was developed whereby people can use "friendly" names that are then translated automatically into IP addresses that computers use to locate each other and to communicate. Before the advent of DNS, HOSTS files were used for name resolution, but as the Internet quickly grew in size and popularity, HOSTS files became impossible to maintain and keep current.
When the Internet community realized there was a need for a more manageable, scalable, and efficient name-resolution system, DNS was created.
This article will cover how to setup dns with dynamic updates aswell as configuring your dhcp server to push updates to it aswell. If there's anything this article doesn't cover with respect to what you are looking for, leave a comment and I'll do what I can.
I assume you already know how to setup plain old dns aswell as plain old dhcp. Dynamic DNS is the means by which to push new records into your dns server while it is running, without having to edit any zone files.
These numbers, also known as Internet Protocol (IP) addresses, consist of four groups of numbers, or octets, and can be difficult for people to remember.
Domain Name Server (DNS) used for name resolving to any hosts.
Master DNS servers (Primary Server) are the original zone data handlers and Slave DNS server (Secondary Server) are just a backup servers which is used to copy the same zone information’s from the master servers.
Since that time, DNS servers have been used on the Internet almost exclusively.
Before the introduction of Windows 2000, Network Basic Input/Output System (Net BIOS) names were used to identify computers, services, and other resources on Windows-based machines.
To assign a different IPv4 address to the mail server, perform the following steps: The system cannot perform automatic detection for this setting if the MX entry does not resolve (for example, if you mistype a domain name or enter one that does not exist).
