Any network engineers here? I have a couple questions I am having difficulty with and was looking for some help.....



1. You are given the class B address space of 189.13.0.0/16 to partition into four subnets. Three of these subnets must be able to address up to 5000 hosts, while the fourth must be able to address up to 18000. Determine the network, mask, and broadcast address for each subnet. You may assume that the broadcast address is the subnet’s highest address.



If I apply a subnet mask of 255.255.192.0 to 189.13.0.0 I get 4 subnets

able to support up to 16382 hosts each.... not enough for the 4th subnet (18000 needed). However, if I make the mask 255.255.128.0 then I can support 32766 hosts but only 2 subnets..


Can you point me in the right direction?


I have more but I thought I'd see how this went first.


Thanks.

One mask is a /17 giving 32K addresses, the other three networks would use a /19 providing 8K addresses.


PM - me if you need more.

189.13.0.1 - 189.13.127.254/17


189.13.128.1 - 189.13.159.254/19

189.13.160.1 - 189.13.191.254/19

189.13.192.1 - 189.13.223.254/19

Last edit - anybody even thinking about putting 18000 hosts on a single IP network should be shot...it would never work. :)

Spidey: I am having a strange medical problem that a number of doctors have been unable to diagnose properly.


Can you help?
