Whatever your application is, BIND 9 probably has the required features. As the first, oldest, and most commonly deployed solution, there are more network engineers who are already familiar with BIND 9 than with any other system.

Users are free to add functionality to BIND 9 and contribute back to the community through our open Gitlab. If you prefer Docker, get our official Docker image. BIND is used successfully for every application from publishing the DNSSEC-signed DNS root zone and many top-level domains, to hosting providers who publish very large zone files with many small zones, to enterprises with both internal private and external zones, to service providers with large resolver farms.

We also maintain a significant feature matrix and changes file. We also have official Docker images. Most operating systems also offer BIND 9 packages for their users. These may be built with a different set of defaults than the standard BIND 9 distribution, and some of them add a version number of their own that does not map exactly to the BIND 9 version. See the Best Practices documents in our Knowledgebase for configuration recommendations.

Resolver users may find Getting started with Recursive Resolvers to be useful. Most users will benefit from joining the bind-users mailing list. We advise all users to subscribe to bind-announce lists. For other news, see our BIND blogs. Our partners at Men and Mice run a very good series of hands-on training classes. An authoritative DNS server answers requests from resolvers, using information about the domain names it is authoritative for.

You can provide DNS services on the Internet by installing this software on a server and giving it information about your domain names. Queries for ANY records are a possible abuse mechanism because they typically extract a response much larger than the query. Not recommended for high-query rate authoritative environments. From BIND 9. Once you have initially signed your zones, BIND 9 can automatically re-sign dynamically updated records with inline signing.

Catalog zones facilitate the provisioning of zone information across a nameserver constellation. Catalog zones are particularly useful when there is a large number of secondary servers.

This feature will automatically propagate new zones added to the primary to the secondary servers, or remove zones deleted from the primary, eliminating the need for separate scripts to do this. Using dnstap enables capturing both query and response logs, with a reduced impact on the overall throughput of the BIND server than native BIND logging. Messages may be logged to a file or to a UNIX socket. Support for log-file rotation will depend on which option you choose.

A DNS authoritative system is composed of a primary with one or more secondary servers. Zone files are established and updated on a primary server. Secondaries maintain copies of the zone files and answer queries. This configuration allows scaling the answer capacity by adding more secondaries, while zone information is maintained in only one place.

The primary signals that updated information is available with a NOTIFY message to the secondaries, and the secondaries then initiate a zone transfer from the primary. There are a number of configuration options for controlling the zone updating process. In the most common application, a web browser uses a local stub resolver library on the same computer to look up names in the DNS. That stub resolver is part of the operating system.

The stub resolver usually will forward queries to a caching resolver, a server or group of servers on the network dedicated to DNS services. Those resolvers will send queries to one or multiple authoritative servers in order to find the IP address for that DNS name. Prefetch popular records before they expire from the cache.

This will improve the performance delivered to end users for resolving names that have short expiration times. From time to time you may get incorrect or outdated records in the resolver cache. BIND 9 gives you the ability to remove them selectively or as a group.

This allows you to give internal on-network and external from the Internet users different views of your DNS data, keeping some DNS information private. BIND 9 offers two configuration parameters, fetches-per-zone and fetches-per-server.

These features enable rate-limiting queries to authoritative systems that appear to be under attack. These features have been successful in mitigating the impact of a DDoS attack on resolvers in the path of the attack. In BIND 9, this is enabled with a single command. The primary application is for blocking access to domains that are believed to be published for abusive or illegal purposes.

There are companies that specialize in identifying abusive sites on the Internet, which market these lists in the form of RPZ feeds. This feature minimizes leakage of excessive detail about the query to systems that need those details. These implementations are available in the development branch today. We also have an official Docker image. Download sources here and follow these instructions to verify a download file.

This guide assumes you have a working installation of Microsoft Windows Server. The instructions and screenshots have been taken using Windows Server Standard Edition with a GUI, but other versions should be similar. The installation of Windows Server is not covered here, but suffice to say a vanilla Windows Server installation is fine. Scroll down the page and click on BIND 9.

Then click the blue Download button next to the most recent Current-Stable version. I strongly recommend using a tool like WinMD5 to verify the signature of the file you downloaded. Find the downloaded file, right-click on it and choose Properties, then tick the Unblock checkbox as shown below, and finally click on OK.

Just extract it to a temporary folder for now, the installation routine will create the folder into which BIND will actually be installed. So you may want to do this next part whilst logged-on as the built-in local Administrator account. That makes it a lot easier when it comes to specifying the path in any configuration files, or when running tools from the command line. Do not enter Administrator here! That would be a terrible idea since it means that if someone manages to exploit your BIND instance they will have full control over your Windows Server.

Choose a unique username for the service, along with a suitably secure password. The installation applet will create the user account with the specified password and grant it appropriate Logon as a Service rights.

Click on Install and the installation applet will start the installation process. If you switched to using the built-in Administrator account then you can now log off and log back on as your normal user account. The BIND command line utilities are all stored in the bin subfolder of the installation folder. Take a look at one of the following guides depending upon your intended use:. Skip to content. Make sure your Windows Server is fully patched and up-to-date then move on to Step 2.

For example, the IP address and port specified in the name parameter are already bound to another socket being used by another application. This error is returned if the specified address pointed to by the name parameter is not a valid local IP address on this computer.

This error is returned if the name parameter is NULL, the name or namelen parameter is not a valid part of the user address space, the namelen parameter is too small, the name parameter contains an incorrect address format for the associated address family, or the first two bytes of the memory block specified by name do not match the address family associated with the socket descriptor s. The bind function is required on an unconnected socket before subsequent calls to the listen function.

It is normally used to bind to either connection-oriented stream or connectionless datagram sockets. When a socket is created with a call to the socket function, it exists in a namespace address family , but it has no name assigned to it.

Use the bind function to establish the local association of the socket by assigning a local name to an unnamed socket. In Windows Sockets 2, the name parameter is not strictly interpreted as a pointer to a sockaddr structure. It is cast this way for Windows Sockets 1. Service providers are free to regard it as a pointer to a block of memory of size namelen.

This allows the underlying service provider to use any appropriate network address, potentially simplifying application programming in the presence of multihomed hosts that is, hosts that have more than one network interface and address.

On Windows Vista and later, the dynamic client port range is a value between and This is a change from Windows Server and earlier where the dynamic client port range was a value between and The maximum value for the client dynamic port range can be changed by setting a value under the following registry key:. The MaxUserPort registry value sets the value to use for the maximum value of the dynamic client port range. Finally we opened a dos box and tried a dig command.

Seemed to run a bit slowly but we got our results. And yes we had already forgotten where we installed bind. Thank goodness we set the path variable.

We have not used the service frequently but we were pleasantly surprised at how easy it was to install. Task Manager shows about K of memory usage which is by no means excessive. The install process creates the required account but we manually set the account up under NT 4. The password entry is optional – you can leave it blank or not as you choose – we left it blank but see NT 4. This is essential to avoid permission errors when you start the BIND service.

Right click properties then permissions and find and select the named account and Add :. Add all permissions except full control and leave the inherit check box set the default :.

Find and double click the path line and Add the following or wherever your BIND9 bin directory is located :. Click OK and exit. Time to start the BIND service.

And yes, we had already forgotten where we installed bind. Note: The We were pleasantly surprised at how easy it was to install. As serious side benefit you get dig and other tools as a bonus.
