Network Hosts Question

[johnny.grizzard]

Hello Everyone,

I am studying to become CCNA certified and I'm practicing/learning subnetting.  I have a workbook student and instructor version but I think the instructor workbook answer to the question is wrong based on what I've learned so far.  Can someone please help me answer the following:

I need 50 hosts and I have a Network Address of 172.59.0.0

Of course the address class is B and the default subnet mask is 255.255.0.0

I need to know the Custom Subnet Mask? (I think it's 255.255.255.192)

The total number of subnets? (I think it's 64)

The total number of host addresses? (I'm not sure about this)  Is there a quick and easy way to find this out?

The number of bits borrowed?

Any help would be greatly appreciated.

Hi

if you want 50 hosts in that subnet this is what you would have

network 172.59.0.0   subnet  255.255.255.192 or /26 and  wildcard 0.0.0.63

172.59.0.1 - 172.59.0.62

62 hosts per subnet 1024 subnets altogether

next subnet 172.59.0.64 hosts 172.59.0.65 - 172.59.0.126 and so on like that till you run out
