Shell Programming and Scripting

Hi
Suppose
You have two computers. One named kenny which has an IP address of 192.168.0.7. kenny lives
on a subnet with a subnet mask of 255.255.255.240. The second computer is called zathras, which
has an IP address of 192.168.0.17, zathras lives on a network with the same subnet mask.

i) When kenny sends packets to zathras, do they need to go through a router?

ii) What is the network and broadcast address for the network that zathras lives on?

kenny has a "network" of 192.168.0.0 with a broadcast of 192.168.0.15. The hosts on this subnet range from 192.168.0.1 - 192.168.0.14.

zanthras has a "network" of 192.168.0.16 with a broadcast of 192.168.0.31. The hosts on this subnet range from 192.168.0.17 - 192.168.0.30.

You need that router.

thanks for the answer, Could u explain a little bit more, how did u come up to that solution

Mr Google will be your friend for general homework type questions (i.e. not real world)
try searching for sub-netting tutorial

I looked it here: RFC 1878 - Variable Length Subnet Table For IPv4
