Introduction To
Subnetting
Introduction
So you have made it this far
hey ? Well you are in for an
AWESOME
ride.
Subnetting
is one of my favorite
subjects. It can be as simple as 1,2,3 or as complex
as trying to get free tech support from Microsoft :)
Getting serious now..
Subnetting
is a very interesting and
important topic. I gather that most of you have
heard about it or have some idea what it's all
about. For those who haven't dealt with subnets
before... hang in there because you're not alone !
Keep in mind we also have the website's forum where
you can post questions or read up on other people's
questions and answers. It's an excellent source of
information and I recommend you use it !
For some reason a lot of
people consider
Subnetting to be a
difficult subject, which is true to some extent, but
I must say that I think that most of them see it
that way because they do not have solid foundations
on networking (essential !), and especially the IP
protocol. But for you guys (and girls), the above
doesn't apply, because we have covered IP in the
best possible way and we
DO
have solid foundations. Right
?
Some Advice !
If you started reading the
IP protocol
on this site from the begining
and have understood everything, then you won't have
any problem understanding subnetting... but (there
is always a darn "but" !) on the other hand if you
do not understand very well what we have been
talking about in the previous pages, then you're
going to find this somewhat difficult. Which ever
the case, I'm going to try and explain subnetting as
simply as possible and hope to answer all your
questions.
Now, because
Subnetting
is a
big topic to talk about and analyse in one page
(yeah right !) I've split it throughout a few
sections to break it down into smaller pieces.
Logically, as you move on to higher sections, the
concepts and material difficulty will increase :
-
Section 3:
The Subnet Mask Bits.
Detailed analysis of
subnet mask bits. Learn to recognise the number
of bits in a subnet mask, followed by an
introduction to complex subnets.
-
Section 4:
Routing and Communications between Subnets.
Understand how routers deal with subnets, how
computers which are in different subnets can
communicate with each other, along with a few
general notes on subnetting that you should
know.
-
Section 5:
Subnetting Guidelines.
Some last information to
help you plan your new networks and a few things
to keep in mind so you can avoid future problems
with subnets.
