In your case the subnet with ip address 12.200.50.0/17 would be 255.255.128.0 since 12.200.50.0/17 means you have 8+8+1 of subnet ID and this being a class A ip address you have the rest of the part as host bits. Please revert if you need any further information. Hey Amit:

I am working right now. force yourself to go line by line, step by step with what Linglom has shown us in the mean time. I will get time for this later. He has given us some good stuff. Scott Ravi,

As per your calculations is it 1024 valid IP's available? 2. Can you show me a detailed calculation of my last question that is how to find the subnet and broadcast IP addresses? I know I am asking too much here but I am really getting into it... and trying to figure out with some easy calculations/maths to figure out the answers to my questions... Hope you would understand... All I need is a step by step calculation of my aforesaid questions as I am new to networking and IP addressing, it will be a pleasure to know the in-depth way of calculating the IP addresses etc... I know Linglom has shown it with an easy math but since I am new to all this I am not able to get it... Your response would be highly appreciated. Regards, Ravi Hi Scott:

(I referred to this as position 10 for my own convenience) Now you have your 10 bit position for the hosts. How else may I help? Scott (Linglom, please check these things. Don't let me show Ravi wrong. I am just answering his questions because I need the challenge.) Ravi,

to get the 10 bit host, use the powers of 2 like this:
1×2=2
2×2=4
2×4=8
2×8=16
2×16=32
2×32=64
2×64=128
2×128=256
2×256=512
2×512=1024 and so on…. (I referred to this as position 10 for my own convenience)
Now you have your 10 bit position for the hosts.
How else may I help?
Scott

For example, why we having a 10 bit host etc... if that could be shown here in this space then it would make my life much easy... I look forward to your explanation...
