Subnetting Help

Normanthefish

I have a Host IP Adress of 183.91.104.16... 11 Bits have been borrowed to create the required subnets.

i am trying to find out the:

What class the address is?
What is the Default Subnet Mask?
Subnet mask for the host in Dotted Decimal and IP Prefex Format?

is there any help you guys can offer me to work these questions out?

Thanks

You are right on your two answers. What about the third?

Thats what i am asking, how do i go about answering it

I assume you can handle the dotted decimal portion since you were able to properly write the class B mask in dotted decimal. So I guess you are struggling with the prefix notation? Luckily this is the easiest part! All you have to do is count the bits used for the network portion.

Example: 10.0.0.1 borrowing 8 bits.

Class = A
Default Mask = 255.0.0.0
Subnet Mask = 255.255.0.0
Prefix Notation = /16

Now just apply that to your scenario and you should be good to go!
