Calculate subnet of network address

By ananadodo ·
I was given the ipaddress of a system and I was told to calculate and give the subnet. I am a complete novice in networking and I don't know where to start. The deadline for submission is 3:53p.m. Please am desperate

There are quite a few ways to do this. I can teach you all the math behind subneting or I can show you some online tools to do it for you. I think given your deadline, the latter of the two is better. The best one I've found (and used in class when I taught it is) at

if not I can make up a subnet chart for you.

Learn To Subnet is one of the best sites on the web for learning this information:

Just an ip could be using any subnet, Standard class A, B or C or
a custom subnet where bits are borrowed from the host portion
of the subnet. Were you given an ip and mask to calculate the
subnet id's? Or, were you given an ip and must create a given
number of subnets with a given number of hosts by using a
custom subnet mask?

Either way this sounds like doing your homework for you so I
hope we all do well.

Refer to Routing TCPIP Vol 1.pdf from Cisco Press Books.

Probably the best place to get the information you need quickly is the calculators there are simple to use, clear and complete.

I must agree with milena, I've found to be easy to use and efficient. It doesn't really aim to be a site directed towards learning to subnet (although I've found it very useful for my CCNA), but has replied to all my subnetting (and cidr) needs admirably - I'll keep going back there.
Highly recomended!!!
