BIND 9 DNS Server on Debian 11

AskforCloud LLC

BIND 9 is transparent open source DNS system , licensed under the MPL 2.0 license.

BIND 9 has evolved to be a very flexible, full-featured DNS system. 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.

BIND 9 is transparent open source, licensed under the MPL 2.0 license. Users are free to add functionality to BIND 9 and contribute back to the community through open Gitlab.

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.

Usage Instructions:

🗸 To check the version number and build options, run - "sudo named -V"
🗸 Check BIND status ,run : "sudo systemctl status bind9"
🗸 If it’s not running, then start it, run: "sudo systemctl start bind9"
🗸 The BIND server listens on TCP and UDP port 53, can be seen by running the command: "sudo netstat -lnptu | grep named"
🗸 Configure DNS Server - DNS server main directory : "/etc/bind".
At bind directory, Two zone file: one is global DNS conf file "named.conf" & second is local DNS config file "named.conf.local".

BIND 9 Features:

🗸 Response Rate Limiting (RRL) : is an enhancement to named to reduce the problem of “amplification attacks” by rate-limiting DNS responses.
🗸 Minimal ANY Responses : Queries for ANY records are a possible abuse mechanism because they typically extract a response much larger than the query.
🗸 DLZ - Dynamically-Loadable Zones (DLZ) enable BIND 9 to retrieve zone data directly from an external database.
🗸 Minimum Re-load Time - Update your BIND 9 server zone files with the remote name daemon control (rndc) utility, without restarting BIND 9.
🗸 HSM Support - HSMs are used to store key material outside of BIND 9 for security reasons.
🗸 DNSSEC with In-line Signing BIND 9 fully supports DNSSEC and has a mature, full-featured, easy-to-use implementation.
