help with network address and subnet

[sexyali]

i'm trying to do the following problem,

 

my query is to work out the network address do i convert the host address to binary along with the supernet and add them together to get the answer

 

and then add the network address to subnet mask to get the subnet address/

thanks in advance

Firstly you need this link:

 

http://jodies.de/ipcalc

 

This will save you alot of time and trouble, once you have used this for a bit you will see what you need to do to get what you need without need to do to much brain work.

 

For you first line you would have:

 

Address: 164.14.83.19 10100100.00001110 .01010011.00010011

Netmask: 255.255.0.0 = 16 11111111.11111111 .00000000.00000000

Wildcard: 0.0.255.255 00000000.00000000 .11111111.11111111

Network: 164.14.0.0/16 10100100.00001110 .00000000.00000000 => (Class B)

Broadcast: 164.14.255.255 10100100.00001110 .11111111.11111111

HostMin: 164.14.0.1 10100100.00001110 .00000000.00000001

HostMax: 64.14.255.254 10100100.00001110 .11111111.11111110

Hosts/Net: 65534

 

That should get you started however you will notice that in your example your subnet mask is incorrect

If this is for your CCNA read the online materials because it will help you with doing this.

 

It's best not to use the online ip calculators and to get used to doing it by hand. Also get used to doing the maths in your head or on paper that you'd use your ordinary calculator for. Just use the calculator to check it or you'll never learn how to do it yourself.

 

In the practical exams for CCNA etc you're not allowed to take in or use any calculators and you have to do it yourself (Well...I'm not allowed) so it's worth learning.

its not for ccna, i did this earlier this year, i dont wanna use a calculator as i wont be allowed a calc in the main exam

 

where i am getting confused is how to work out the network address and subnet address, i do not know which to convert

 

i have the host address and i know this needs to be converted to binary and added to either the supernet or the subnet mask but not sure,

 

below is an example i have done

 

10100100 00001110 01010011 00010011 (host_address)

11111111 11111111 00000000 00000000 (supernet)

---------------------------------------

10100100 00001110 00000000 00000000 = network address or subnet mask?

 

i'm not sure if i 've worked out the network address or subnet address, your help will be much appreciated.

 

thanks.

i've had a go on the first example,

 

here's wot i have worked out so far

 

network address = Host_ad + Subnet mask

 

10100100.00001110.01010011.00010011 (host_address)

11111111.11111111.11111111.00000000 (subnet_mask)

-----------------------------------------------

10100100.00001110.01010011.00000000 (network address) = 164.14.83.0

 

Subnet Address = Net_ad + supernet

 

10100100.00001110.01010011.00000000 (network Address)

11111111.11111111.00000000.00000000 (Supernet)

-----------------------------------------------

10100100.00001110.00000000.00000000 (subnet address) = 164.14.0.0

 

 

have i dont this correctly?
