"Fundamentals of DNS"


Hello,

Please let me know the fundamentals of DNS ? mean to say that can I know how DNS works on the network? How to configure it on the server ? Thus it can prove as a GREAT resource, especially for beginners like me. Could someone please supply me with examples and also point me in the right direction for DNS.

Thankyou.

I had the very same questions that you have.
The DNS and Bind 4th edition book can answer all your questions.

A portion on the preface of the book sais:

You may not know much about the Domain Name System − yet − but
whenever you use the Internet, you use DNS. Every time you send
electronic mail or surf the World Wide Web, you rely on the
Domain Name System.

You see, while you, as a human being, prefer to remember the names
of computers, computers like to address each other by number.
On an internet, that number is 32 bits long, or between zero and four
billion or so. That's easy for a computer to remember, because computers
have lots of memory ideal for storing numbers,
but it isn't nearly as easy for us humans. Pick ten phone numbers
out of the phone book at random, and then try to remember them.
Not easy? Now flip to the front of the book and attach random area
codes to the phone numbers. That's about how difficult it would be
to remember ten arbitrary internet addresses.

[1] And, with IP version 6, it's soon to be a whopping 128 bits
long, or between zero and a decimal number with 39 digits.

Good Luck

-W

Maybe you also want to have a look at the RFC at http://www.ietf.org/rfc/rfc1035.txt and a list of other DNS-related RFCs at http://www.dns.net/dnsrd/rfc/

Just a thought.

-/quote-

That's exactly why I pointed out DNS and BIND. That
book explain everthing you need to know, wether you
are a n00b, intermediate or advanced. It is the
best way to learn DNS that I've found so far. May
be there is better litterature but since all my questions
were answered rather well in this book I didn't use
any other. Now, if you are looking for someone to
explain to you in "deep" what DNS is and does, you
are going to end up reading the same thing that is
written in that book an so many other, with a few
exeptions. Here is a link to a site with a shorter
explanation, but is more related to Debian and lack
good in depth explanations.

Good Luck
