NSD is an authoritative only, memory efficient, highly secure and simple to configure open source domain name server.
NSD (name server daemon) is a server implementation for the Domain Name System (DNS).
NSD is an authoritative only, high performance, simple and open source name server. NLnet Labs has a long term commitment for supporting NSD.
NSD is thoroughly tested, there is a regression tests report available: For NSD 4.0, the memory estimation tool can be compiled in the source tarball with 'make nsd-mem' and running it on a config file with the zone files in question.
A dedicated validating, resolving caching DNS program like Unbound DNS (unbound.conf) is a perfect compliment to NSD allowing you to split your authoritative and resolving servers for significantly better security.
NSD uses BIND-style zone-files; zone-files used under BIND (named) can usually be supplied unmodified in NSD once declared in the configuration.
To solve this problem, alternative DNS servers have been created that specialize in a single area of DNS resolution.
A piece of software known as NSD is an authoritative-only DNS server that is ideal for managing DNS zones authoritatively.
NSD was conceptually built from scratch as a purely authoritative name server; not implementing the recursive caching function by design.Microsoft is conducting an online survey to understand your opinion of the Technet Web site.If you choose to participate, the online survey will be presented to you when you leave the Technet Web site. The solution: DNSSEC configured authoritative DNS servers prevent this kind of attack by digitally signing each resource record with a private key.The DNS resolver verifies the integrity of a zone record using the public key and the digital signature.
