How to Configuring DNS Zones with step by step screen shots


DNS Zones sorts at a glance:

DNS encompasses a hierarchical data structure tree known as “DNS namespace” that enables it to support any size of networks (The native network, the net for examples) with none issues regarding quantifiability. the basis domain will have several subdomains and also the subdomains will produce other sub-subdomains.. etc. Any organization will use personal DNS namespace among the organization while not creating it visible to the surface (internet) .

Domain name servers DNS store data regarding portion of the domain namespace known as a “zone” that could be a contiguous portion of the namespace wherever a selected server is authoritative. DNS servers maintain zone files and DNS resource records, the zone files offer the data for the various zones that the server is authoritative, whereas The resource records area unit DNS information entries that area unit accustomed answer DNS queries.

Note:

For a server to be authoritative for a selected domain it should answer the shoppers queries supported a domestically hosted information or zone file. Zone files area unit used if DNS isn't integrated with Active Directory.

A single name server may be authoritative for several zones.

Zones types:

In the previous post regarding putting in DNS server “Installing DNS server on a standalone or member server“ I even have put in the DNS server on a standalone server. during this rehearse i'll continue with identical situation by making and configuring zones manually on a standalone server or on a member server.

There area unit 3 varieties of DNS zones: Primary, Secondary and Stub zone. In term of address translation practicality – if i could use the term – there area unit 2 varieties of them: Forward zone and Reveres zone. Reverse search zones accustomed resolve science addresses to human friendly addresses whereas the Forward zones resolve addresses to science.

Primary Zone: Provides an imaginative read-write supply of the information for all domains within the zone. It permits the native DNS server to update and answer DNS quires magisterially.

Secondary Zone: Provides AN authoritative nonetheless read-only copy of the first Zone or another Secondary Zone. The supply zone from that the secondary zones has been traced area unit known as Masters.

Stub Zone: Provides resource records necessary to spot the authoritative DNS servers for the master zone, principally accustomed get AN updated list of the servers during a delegated kid zone.

Storing Zones in Active Directory: this selection is accessible given that you produce a Primary or a Stub Zone on a website controller, it permits you to integrate the zone into Active Directory and replicate the zone knowledge through Active Directory mechanically. Active Directory integrated zone is on the far side the scope of this post and can be mentioned in details in another post. Hopefully : )
