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.
