Well, the subnet mask would be 255.255.255.0.

Might be an idea to say hello in the New Members Introduction

 

thanx a lot buddy......................


and a heartfelt hello..................................

 

You might want to learn to subnet in general. This site really works:

wanna learn to subnet?

 

I beat you to it, Mr. Cheeks.

 

Sure you did Mr. Site Administrator... ...i *believe* you

 

NETWORKMANIAC,

How you subnet that network depends on the design requirements of:

1. Required number of subnets or
2. Required number of hosts per subnet or
3. Required number of subnets AND number of hosts per subnet
4. Other (to include variable length subnet masking)

 

yup buddy thats ok,but further how you continue with all that stuff wen you have to make a chart includin range also?????????????????????/

 

NETWORKMANIAC,

The "...how you continue..." completely depends on which case as listed above under 1., 2., 3.,, or 4. So which case is this subnetting of network 100.100.100.0/24 for?

 

the first three.............

 

NETWORKMANIAC,

Here's how this thing works. You choose 1 or 2 or 3 or 4. You can't choose more than one. So which _one_ do you choose?

 

HI networkmanic, if you want to learn to subnet in less than 10 minutes, try the attached doc

 

If you haven't got the time, but need to know the answers try this one;

 

You can have (*Edit, this is when you do not use variable Length Subnetting, as all the possibilities would make the forum server run out of mysql database space! - Ok j/k)

1 Subnet

which is

100.100.100.0 - 100.100.100.255
usable addresses range from
100.100.100.1 - 100.100.100.254
Netmask
255.255.255.0 or /24

2 subnets

100.100.100.0 - 100.100.100.127
100.100.100.128 - 100.100.100.255

usable addresses range from
100.100.100.1 - 100.100.100.126
and
100.100.100.129 - 100.100.100.254
Netmask
255.255.255.128 or /25

4 subnets

100.100.100.0 - 100.100.100.63
100.100.100.64 - 100.100.100.127
100.100.100.128 - 100.100.100.191
100.100.100.192 - 100.100.100.255

usable addresses range from
100.100.100.1 - 100.100.100.62
100.100.100.65 - 100.100.100.126
100.100.100.129 - 100.100.100.190
100.100.100.193 - 100.100.100.254
Netmask
255.255.255.192 or or /26

and there are more, (up until you get to a /30 address - which is commonly used with VLSM and router connections (as they only need 2 hosts).

Basically you will need to get a grasp of IP, bit notation (the 11110000), Broadcast and Network addresses and much more its quite a learning curve.

And for the CCNA exam you will need to be FAST.

 

A 24 bit subnet mask on a class A network address is different from a 24 bit subnet mask on a class C network address. Class rules specify a 24 bit subnet mask for class C network addresses only. In this class A address example, there would be 65,536 subnets with 256 hosts each. Usable hosts in each subnet are 100.0.0.1 - 100.0.0.254, 100.0.1.1 - 100.0.1.254, 100.0.2.1 - 100.0.2.254,............. 100.254.254.1 - 100.254.254.254. Somebody please correct me if I am mistaken here. This is how I understand it, and if I am wrong, I need to know.
