Q#1: What is IP address and also define classes of IP address?

Ans: IP ADDRESS:

"IP" stands for Internet Protocol, so an IP address is an Internet Protocol address. What does that ...view middle of the document...

Static IP addresses reveal such information as the continent, country, region, and city in which a computer is located; the ISP (Internet Service Provider) that services that particular computer; and such technical information as the precise latitude and longitude of the country, as well as the locale, of the computer. Many websites provide IP address look-up services to their visitors, free of charge. If you're curious about your own IP address, you can locate these websites by performing a Google search.
Dynamic IP addresses are temporary and are assigned each time a computer accesses the Internet. They are, in effect, borrowed from a pool of IP addresses that are shared among various computers. Since a limited number of static IP addresses are available, many ISPs reserve a portion of their assigned addresses for sharing among their subscribers in this way. This lowers costs and allows them to service far more subscribers than they otherwise could.
Static IP addresses: are generally preferable for such uses as VOIP (Voice over Internet Protocol), online gaming, or any other purpose where users need to make it easy for other computers to locate and connect to them. Easy access can also be facilitated when using a dynamic IP address through the use of a dynamic DNS service, which enables other computers to find you even though you may be using a temporary, one-time IP address. This often entails an extra charge, however, so check with your ISP.
Static IP addresses are considered somewhat less secure than dynamic IP addresses, since they are easier to track for data mining purposes. However, following safe Internet practices can help mitigate this potential problem and keep your computer secure no matter what type of IP address you use.[1]
CLASSES OF IP ADRESSES:

IP addresses were originally organized into classes. The address class determined the network’s potential size.
An address‘s class specified which of the bits were used to identify the network and the network ID, or which bits were used to identify the host ID and host computer. It also defined the total number of hosts subnets per network. There were five classes of IP addresses: classes A through E.
Classful addressing is no longer commonly used and has now been replaced with classless addressing. Any netmask can now be assigned to any IP address range.

Network and Host ID Fields

The four octets that make up an IP address are conventionally represented by a, b, c, and d respectively. The following table shows how the octets are distributed in classes A, B, and C.
|Class |IP Address |Network ID |Host ID |
|A |a.b.c.d |a |b.c.d |
|B |a.b.c.d |a.b |c.d |
|C |a.b.c.d |a.b.c |d |

Class A: Class A addresses are specific to networks with a large number of total hosts. Class A allows 126 networks by using the first octet for the...
