Chapter 5: Network Protocols

Given the IP address 134.141.7.11 and the mask 255.255.255.0, what is the subnet
broadcast address?

__________________________________________________________________

Given the IP address 200.1.1.130 and the mask 255.255.255.224, what are the
assignable IP addresses in this subnet?

Given the IP address 220.8.7.100 and the mask 255.255.255.240, what are all the
subnet numbers if the same (static) mask is used for all subnets in this network?

__________________________________________________________________

Create a minimal configuration enabling IP on each interface on a 2501 router (two
serial, one Ethernet). The NIC assigned you network 8.0.0.0. Your boss says that you
need, at most, 200 hosts per subnet. You decide against using VLSM. Your boss says
to plan your subnets so that you can have as many subnets as possible, rather than
allow for larger subnets later. You decide to start with the lowest numerical values for
the subnet number you will use. Assume that point-to-point serial links will be
attached to this router and that RIP is the routing protocol.

__________________________________________________________________

Describe the question and possible responses in setup mode when a router wants to
know the mask used on an interface. How can the router derive the correct mask
from the information supplied by the user?
