BIND:suite for interacting with the Domain Name System (DNS)

BIND is a software suite for interacting with the Domain Name System (DNS). As of 2015, it is the most widely used domain name server software and is the de facto standard on Unix-like operating systems. Its most prominent component, named (pronounced name-dee: /ˈneɪmdiː/, short for name daemon), performs both of the primary DNS server roles, acting as an authoritative name server for DNS zones and as a recursive resolver in the network. Also contained in the suite are various administration tools, such as nsupdate and dig, and a DNS resolver interface library.

BIND 9 is intended to comply fully with the IETF DNS and draft standards. Essential features of BIND 9 include TSIG, nsupdate, IPv6, RNDC (remote name daemon control), views, multiprocessor support, Response Rate Limiting (RRL), DNSSEC, and broad portability. RNDC enables remote configuration updates, using a shared secret to provide encryption for local and remote terminals during each session.

While earlier versions of BIND offered no mechanism to store and retrieve zone data in anything other than flat text files, in 2007, BIND 9.4 DLZ provided a compile-time option for zone storage in a variety of database formats including LDAP, Berkeley DB, PostgreSQL, MySQL, and ODBC.

BIND 10 planned to make the data store modular so that a variety of databases may be connected. In 2016 ISC added support for the 'dyndb' interface, contributed by RedHat, with the BIND version.

Security issues discovered in BIND 9 are patched and publicly disclosed in keeping with standard principles of open-source software. A complete list of security defects discovered and revealed in BIND9 is maintained by Internet Systems Consortium, the current authors of the software.

The BIND 4 and BIND 8 releases both had serious security vulnerabilities. Use of these ancient versions or any un-maintained, non-supported version is strongly discouraged.BIND 9 was a complete rewrite to mitigate these ongoing security issues. The downloads page on the ISC website clearly shows which versions are currently maintained and which are end-of-life.

Welcome to Bind9 DNS Server Deployment Instructions:

1. Open the command line tool and run the following command to verify DNS Bind9 Server.

dig nameserver.mydomain.com

Here, nameserver.mydomain.com can be any domain name or

To launch an instance from the AWS Marketplace using the launch wizard

Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
From the Amazon EC2 dashboard, choose Launch Instance.
On the Choose an Amazon Machine Image (AMI) page, choose the AWS Marketplace category on the left. Find a suitable AMI by browsing the categories, or using the search functionality. Choose Select to choose your product.
A dialog displays an overview of the product you've selected. You can view the pricing information, as well as any other information that the vendor has provided. When you're ready, choose Continue.
On the Choose an Instance Type page, select the hardware configuration and size of the instance to launch. When you're done, choose Next: Configure Instance Details.
On the next pages of the wizard, you can configure your instance, add storage, and add tags. For more information about the different options you can configure, see Launching an Instance. Choose Next until you reach the Configure Security Group page.
The wizard creates a new security group according to the vendor's specifications for the product. The security group may include rules that allow all IP addresses (0.0.0.0/0) access on SSH (port 22) on Linux or RDP (port 3389) on Windows. We recommend that you adjust these rules to allow only a specific address or range of addresses to access your instance over those ports.
When you are ready, choose Review and Launch.
On the Review Instance Launch page, check the details of the AMI from which you're about to launch the instance, as well as the other configuration details you set up in the wizard. When you're ready, choose Launch to select or create a key pair, and launch your instance.
Depending on the product you've subscribed to, the instance may take a few minutes or more to launch. You are first subscribed to the product before your instance can launch. If there are any problems with your credit card details, you will be asked to update your account details. When the launch confirmation page displays
