What else can I help you with?
What is used to avoid assigning entire addresses of particular class to networks that did not have that many host?
CIDR
What is used to avoid assigning entire addresses of a particular class to networks that didnt have that many hosts?
NAT
What protocols have made rarp largely unnecessary on modern tcp ip networks?
BOOTP, and eventually DHCP, replaced RARP. Both BOOTP and DHCP offer a more robust, flexible method of assigning IP addresses.

What is network address in IP?
ip addressing is simply configuring the router for your local network by assigning IP addresses for each client in your network creating logical networks inside your local network. for more info see related link.
Which OSI layer addresses data messages translates logical addresses into actual physical addresses and routes data to addresses on the networks?
Network layer
Why do the number of possible IP addresses decrease as you step down from Class A to Class C IP addresses?
That is because it was designed that way. A few big networks, a larger amount of medium-sized networks, and a lot of small networks.
What do most networks use to dynamically assign addresses?
DHCP
How many networks and addresses are available for class b ip addresses?
First octet rule for each class:Class A: 0xxxxxxxClass B: 10xxxxxxClass C: 110xxxxxClass A range is 0 - 1270.0.0.0 and 127.0.0.0 are not "routable" IP addresses. One defines all networks and the other is the loopback. We have a total of 126 usable networks and 16,777,214 usable hostaddresses per network. There are even less if we don't count the private address of 10.0.0.0 (RFC 1918).Class B range is 128 - 191There are 16,384 total networks in this class; that's including the private addresses of 172.16.0.0 - 172.31.0.0 (RFC 1918). There are a total of 65,534 usable host addresses per network.Class C range is 192 - 223There are 2,097,152 total networks in this class; that's including the private addresses of 192.168.0.0 - 192.168.255.0 (RFC 1918). There are 254 usable hosts addresses per network.
When and where can use the IP-address and the MAC-address?
802.11 use MAC addresses, which are the same as IP addresses in some networks
Why ip addresses are dynamic?
== == Dynamic IP addresses are most frequently assigned on LANs and broadband networks by Dynamic Host Configuration Protocol (DHCP) servers. They are used because it avoids the administrative burden of assigning specific static addresses to each device on a network. It also allows many devices to share limited address space on a network if only some of them will be online at a particular time. In most current desktop operating systems, dynamic IP configuration is enabled by default so that a user does not need to manually enter any settings to connect to a network with a DHCP server. DHCP is not the only technology used to assigning dynamic IP addresses. Dialup and some broadband networks use dynamic address features of the Point-to-Point Protocol. source: http://en.wikipedia.org/wiki/IP_address
A router that has 4 ports will require how many IP addresses?
It depends on how many interfaces of router are connected to other networks. If a router is connected to two network, it will have 2 IP addresses. In a router having 4 ports it can connect to maximum 4 networks. In this case it will have 4 IP addresses.
