subnetting (helps security)

I am studying subnetting and I have a few question, if you do not mind.

1. why will the network number be 0 if we borrow just 1 bit?

2. is my table correct?
Usable Sub/Hosts (Total S/hosts - 2)

62
30

Total Sub/ hosts (256 - Sub/mask)

Total subnets

Usable subnets

3. why is the total number of subnet hosts the same as the last borrowed
bit's value?
4. why is the max number of subnets equal to the number 2 powered by the
number of the borrowed bits?
5. why do we use the ANDing method to find out if a certain IP address is
within a subnet?

Thanks in advance!

Sorry, I have to send the table in rich text format ....

Sure, That's a fair question, however, the table shows that I am working on
my homework. and you do not have to answer

Sure, you can send me a bill. lol btw, isn't my table a homework
indication?
Anyway, I am looking only for short answers, not for details, kindly stating
"if you do not mind".

The problem is most people DO mind doing your homework for you, even in
part, and you blatantly posted the entire assignment and asked us to just
fill it all in. You didn't even try and then come to us asking for
something you were having trouble with.

The assignment given to YOU for a reason. You're suppose to be learning
something in the process, even if it's just where to look for the
information if you need to refer back to it. Many of us have already been
through this process, done the work ourselves, and some of us even teach
others now.

Answering all your questions doesn't do you or anyone else any good at
all. No amount of sarcasm and adolescent "you don't have to answer"
bullshit will change that. If anything, it will considerably lower your
chances that anyone will be willing to bother replying at all. Let alone
do anything but spank you.

Why don't you try investing a little of your OWN time and effort first.
If you find you're just not up to the task you might make another attempt
to get help in a public forum, with something a little more genuine than
"Here's my worksheet, fill it out. Please". I'll bet you more people would
reply, and you'd find the answers a WHOLE lot more appealing.

Or..... you could puff your chest out some more and reply like most kids
do in your situation, and get yourself labeled as a useless twit.

Either way makes absolutely no difference in MY life, because you're the
one with the problems that need answers. None of us have anything at all
to loose by not doing your work for you. We may even GAIN something down
the road by not doing it.

Think about it.

Who is "us" ? Do you mean yourself ? Are you_the owner_of this forum?
I did not ask those questions to you personally, and from what I can see,
attacking people is the only thing you do for free. Asking questions and
exchanging opinions are ways to learn, but arrogants like you try to
discourage people from learning this way just because you happened to learn
something by paying big bucks and spending a great deal of time. First time
that you attacked me, I tried to let it go, politely, but you seem to be an
annal.
Who are you to judge people if they ask right or wrong questions? Who told
you to read my posts in the first place, and why do you feel you have to
answer, no matter what ??? Do you know me, do you have any idea what I do
and why I am trying to get a better understanding of subnets? Why do you
assume (make an ass of yourself) that this is an assignment given to me?

Sarcasm and bullshit seem to be your best qualities, because your first
reaction was "Will we get paid for doing your homework?"

Nobody forces anybody to answer all, or part of questions, and you are
making a big mistake by teaching morals to people that do not ask for it!

If anything, it will considerably lower your

There are many nice, intelligent, helpful people in this forume, such as Mr.
Moe (old guy) and many others, so do not speak on behalf of the others. I
wish I could contact some of those people directly and, honestly, I wouldn't
mind even paying them for certain things!!!

I think this description fits your personality perfectly!

You see anyone else in a rush to do your work for you junior? Or even
defend your lazy, ignorant ass? That would tell anyone with an IQ larger
than their shoe size something.

I don't own this group, but I sure as **** own you.

What a lying little Muppet you are. You weren't trying to LEARN anything,
you were trying to get everyone else to do your work for you. If that's
called "learning" In Canada it's no wonder they're third world.

You deserve every bit of ridicule that's heaped on you and more. The first
"attack" was highly restrained compared to the heaping pile of **** you
probably should have been served.

> Who are you to judge people if they ask right or wrong questions? Who

I'm the guy reading your lazy ass lying bullshit and shoving it back down
your throat sonny.

> told you to read my posts in the first place, and why do you feel you

WE know everything we NEED to know about you. You're a masturbatory
asshole who thinks people own him answers when he asks, and respect when
he doesn't deserve it. And you're a juvenile fukwit who stomps his feet
and screams like a little bitch when someone points that out.

If you had just a LICK of sense you you'd have let it go after the first
small jab to your ribs, but no.... here you are making yourself look like
a TOTAL ASSTARD by trying to defend your own laziness by acting like a
child.

Way to go, dimbulb.

You think I look like the ass here junior?

LOL!

Borrow a mirror and look for a clue.

That wasn't sarcasm.

Just because you have no morals and admit it, doesn't mean you're immune
from having your amoral ass kicked from one end of Usenet to the other.
Sorry about your luck.

Then why the **** are you asking for all the answers to your homework for
nothing liar? If you wanted to pay someone you could have done it out in
the real world.

You're a lazy, lying asshole. From the top of your pointy head to the
bottoms of your stomping little feet.

> Get a life!

I have one. YOURS!

In fact I now grant you my permission to have the last word because I know
it's something you need to do to massage your battered sense of manhood
and bolster your shattered little ego.

Good day, looser.

I don't know how much corroboration you'll require before you get the
point here, but I'll chime in by saying I don't particularly care for
the delivery, however the guy's message is dead nuts.

Your request was arrogant and presumptive. You did absolutely no work
on your own apparently, and yet you still seem to think that everyone
else has some moral obligation to give you all the answers, and only
the ones *you* want.

And yes, you're missing the entire point of doing homework. It's not
about simply getting the answers right, it's about the learning
process and how you address problems on your own. That's something you
need to consider carefully.

I am studying subnetting and I have a few question, if you do not mind.

1. why will the network number be 0 if we borrow just 1 bit?

Ok, I guess I have to expand on my questions, but if you do not have
anything nice to say, please do not reply to my post at all.

I will take as an example the network address, 192.168.1.0 The default
subnet mask is 255.255.255.0
The host addresses will be 192.168.1.1 up to 192.168.1. 254 where
192.168.1.255 is the broadcast.

If I borrow 1 bit (subnet mask 255.255.128.0) the result is:
126 usable hosts: 192.168.1.1 to 126; and 2 subnets as follows:
Subnetwork ID broadcast ID
192.168.1.0 192.168.1.127
192.168.1.128 192.168.1.255

The ID of the first Subnetwork (0) is the same as the original network and
the broadcast ID of the second subnetwork (1) is the same as the broadcast
of the original network. However, I am missing something simple ( as it's
always the case and hoped somebody would give me at least a hint.

Are we going to be paid for doing your homework?
