DNS Authoritative

DNS Authoritative

The DNS authoritative name server are domain name servers which return a queries that have only the original record source code from its master administrator configuration setup allows. DNS authoritative normally works with two main concepts the web server is going to deliver back the return of authoritative internet domain name server responses or the D.N.S can be set so it won’t cache any records.
The Requirements that you will knead in setting up your own authoritative DNS server are one or greater number of static IP addresses from your intern provider. The name registries require you to have two or above number of fixes IP addresses this is the rule of thumb in most cases. The zones can be set to master or slave for one or more of the domains has to be set for running an authoritative DNS.
This is used in some ways like a fire wall for example, if your internet domain administrator configuration setups or by dynamic DNS methods, can bring back a different query answers compared to a regular DNS query on another domain name server. The DNS authoritative only name server will just return only the query answer for the domain names system that have been dedicated or aloud in the specifically configured by the administrator.

The dns authoritative name-server can be a master domain or a slave server system. A master server stores the original file copies of all zone records the country registrar is going to require your server to have the entire different zone to be authoritative dns for set up beforehand you submit for registration.
An example of a bind zone file
$TTL 86400
@ IN SOA ns1.dns4you.com. dnsadmin. somesite.com. (

2010022427 ; Serial number
864000 ; Refresh after 10 days (secs)
36000 ; Retry after 100 mins
3600000 ; Expire after 42 days
864000 ) ; Minimum TTL 10 days


IN NS ns1. somesite.com.
IN NS ns2. somesite.com.

IN MX 0 mail

IN A xx.xx.xx.xxx

ns1 IN A xx.xx.xx.xxx
ns2 IN A xx.xx.xx.xxx

mail IN A xx.xx.xx.xxx

www IN A xx.xx.xx.xxx
ftp IN CNAME www.somesite.com.


The slave dns server communications with the DNS protocols to update the master system to automatic maintain an identical backup file copy of the master records.

All of the Domain name server NS zones should have a bind configuration definition and are to be assigned their own group of authoritative name servers that are placed into the parent zone NS records.

When you buy internet domain and then have it registered at the domain registrar service their installation setup in the domain registry has a top level domain that requires the assigning to the primary name server along with the accompaniments of least one or more secondary naming system. The main reason for the several servers is to make the domain constantly in action even if ether the name slave or master server kicks the dust and becomes inaccessible or corrupted in some way. The final designation point of the primary is singularly determined with its DNS authoritative priority settings imputed at the internet domain registrar service. For this application use mostly fully qualified domain names of the name server are applicable or a DNS accommodate at the registered domain in circumstance a corresponding IP address is necessary also.

Description The fifth edition covers BIND 9.3.2, the most recent release of the BIND 9 series, as well as BIND 8.4.7. BIND 9.3.2 contains further improvements in security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). Whether you're an administrator involved with DNS on a daily basis or a user who wants to be more informed about the Internet and how it works, you'll find that this book is essential reading.

Description The fourth edition of DNS and BIND covers the new 9.1.0 and 8.2.3 versions of BIND as well as the older 4.9 version. There's also more extensive coverage of NOTIFY, IPv6 forward and reverse mapping, transaction signatures, and the new DNS Security Extensions; and a section on accommodating Windows 2000 clients, servers and Domain Controllers.

Description The DNS & BIND Cookbook presents solutions to the many problems faced by network administrators responsible for a name server. This title is an indispensable companion to DNS & BIND, 4th Edition, the definitive guide to the critical task of name server administration. The cookbook contains dozens of code recipes showing solutions to everyday problems, ranging from simple questions, like, "How do I get BIND?" to more advanced topics like providing name service for IPv6 addresses.

Description DNS on Windows Server 20003 is a special Windows-oriented edition of the classic DNS and BIND, updated to document the many changes to DNS, large and small, found in Windows Server 2003. Veteran O'Reilly authors, Cricket Liu, Matt Larson, and Robbie Allen explain the whole system in terms of the new Windows Server 2003, from starting and stopping a DNS service to establishing an organization's namespace in the global hierarchy.

Description This special Windows-oriented edition of the classic DNS and BIND is a guide to one of the Internet's fundamental building blocks: the distributed host information database responsible for translating names into addresses, routing mail, and many other services. Covers server setup and maintenance along with Windows-specific topics like integration between DNS and Active Directory, conversion from BIND to the Microsoft DNS server, and registry settings.

This Open Source Guide is about DNS and (mostly) BIND 9.x on Linux (Fedora Core), BSD's (FreeBSD, OpenBSD and NetBSD) and Windows (Win 2K, XP, Server 2003). It is meant for newbies, Rocket Scientist wannabees and anyone in between. This Guide was born out of our first attempts a number of years ago at trying to install a much needed DNS service on an early Redhat Linux system. We completed the DNS 'rite of passage' and found it a pretty unedifying and pointless experience.

The Concise Guide to DNS and BIND provides you with the technical depth and expert-level information you need to understand and administer DNS and BIND. Domain Name System (DNS) is a distributed Internet directory service. It is used mainly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, Web sites cannot be located and email delivery stalls. BIND (Berkeley Internet Name Daemon) is an implementation of the Domain Name System (DNS) protocols.

The BIND 9 DNS Administration Reference Book is based on Internet Systems Consortium's BIND 9 documentation including the Administrator Reference Manual (Bv9ARM). In addition to hundreds of improvements (most integrated upstream) and major reorganization of the original documentation, new content, examples, detailed indexing and more cross-referencing were added. This book is an excellent resource which provides a convenient way to find BIND 9 documentation and to learn DNS basics.

Dru Lavigne's new book is simply the best FreeBSD how-to book out there. This book is well written with specific instruction on how to make things work. Make no mistake about it.....Whether you are a novice or a system administrator, you need this book in your library. Unlike other FreeBSD books out there which basically copy the online handbook, Dru Lavigne compiled literally hundreds of FreeBSD tricks in this new book. You won't be disappointed!
