BIND 9

BIND (Berkeley Internet Name Domain) is the most widely used DNS server software in the world. Version 9, the current major release, is a complete rewrite that provides authoritative DNS, recursive DNS, and DNSSEC support in a single, mature, and battle-tested package.

BIND 9 is the default DNS server included with most Linux distributions and is used by the majority of internet DNS infrastructure. cPanel servers use BIND as their default nameserver for hosting customer DNS zones. The software reads zone files in the standard format that has been the foundation of DNS since the beginning, making it universally compatible.

For hosting providers, BIND typically handles the authoritative DNS for all customer domains. When a hosting account is created, the control panel (cPanel, Plesk, DirectAdmin) automatically generates a BIND zone file with the correct A records, MX records, CNAME records, and other DNS entries. BIND serves these zones in response to DNS queries from resolvers around the world.

BIND 9 supports DNSSEC for cryptographic authentication of DNS responses, TSIG for secure zone transfers between primary and secondary nameservers, Response Rate Limiting (RRL) to mitigate DNS amplification attacks, and catalog zones for automatic secondary zone provisioning.

While PowerDNS has gained popularity for its database backends and API, BIND remains the default choice for most hosting deployments due to its ubiquity, extensive documentation, and the fact that virtually every DNS tutorial and hosting guide assumes BIND. The ISC (Internet Systems Consortium) maintains the project and provides commercial support for enterprise deployments.
