A name server is a server that hosts a network service for providing responses to queries against a directory service. It maps a human-recognizable identifier to a system-internal, identification or addressing component, the program BIND is the most famous name server available on Linux, it can be used to do everything you need from a name server, but sometimes you need less.
Maybe you have a VPS and you want just to manage your DNS name, for this use you could check NSD a great alternative to BIND, it does not do DNS forwarding, it only serves its own domains. but this could be enough for your project.
NSD uses BIND-style zone-files; zone-files used under BIND (named) can usually be supplied unmodified in NSD once declared in the nsd.conf configuration. NSD manages zone information compiled via ‘zonec’ into a binary database file (nsd.db) which allows lightning fast start up of the NSD name-service daemon, syntax structural verification and flagging of errors at database compile-time. All this before being made available to NSD service itself.
Let’s see how to install and configure it.
