This is a reconfigured open-source software product, and there are additional fees associated with obtaining support and maintenance services.
BIND 9 has undergone a significant transformation, becoming a highly adaptable and feature-rich DNS system. Regardless of your specific application, BIND 9 likely offers the essential functionalities you need. Being the pioneer and one of the most widely deployed solutions, BIND 9 boasts a large community of network engineers who are already well-versed in its usage.
It’s worth noting that BIND 9 is an open-source solution, governed by the MPL 2.0 license. This open nature allows users to extend the capabilities of BIND 9 and actively contribute to the open-source community via Gitlab.
Notable Features of BIND 9:
Response Rate Limiting (RRL): This feature is an enhancement to the “named” DNS server, designed to mitigate the issue of “amplification attacks” by limiting the rate of DNS responses.
Minimal ANY Responses: BIND 9 efficiently handles queries for ANY records, preventing potential misuse scenarios where such queries could result in overly large responses.
DLZ – Dynamically Loadable Zones (DLZ): BIND 9 empowers users to dynamically retrieve zone data directly from external databases, offering greater flexibility in managing zones.
Minimum Reload Time: This feature simplifies the process of updating server zone files in BIND 9 using the remote name daemon control (rndc) utility, eliminating the need to restart BIND 9.
HSM Support: Hardware Security Modules (HSMs) play a critical role in securely storing key material external to BIND 9, enhancing overall security measures.
DNSSEC with Inline Signing: BIND 9 provides robust support for DNSSEC, offering a mature, comprehensive, and user-friendly implementation of this essential security feature.
