Is Secure64 DNS Authority based on BIND?
It is important to have genetic diversity in the DNS, to provide resiliency against attacks that attempt to exploit flaws in any particular implementation. Secure64 DNS Authority is adapted from NSD, an open-source authoritative DNS implementation available through NLNet Labs. NSD was designed for performance and simplicity, and it has been used in production for many years to power root servers and top-level domains.
