Let us begin with IP Addresses.
What is an IP Address?
► An Internet Protocol address is a numerical label assigned to each device (e.g., computer, mobile phone) that is connected to a computer network that uses the Internet Protocol for communication.
► An IP address is used for two purposes:
1) To identify whether the interface is host or network.
2) To determine the location of the device.
► IP Versions: IPv4 and IPv6.
Although IPv4 is the earlier version, it is the most commonly used version.
► IPv4 is a 32-bit decimal number while IPv6 is 128-bit number.
► IPv4 is normally written as four numbers between 1 and 255, each separated from the other by a decimal point.
This standard is called as DOTTED-DECIMAL NOTATION.
► Ex: 115.241.40.93
► There are countless IP addresses in today's world!
See for which purpose we need the IP Address------
------------------------------
What is the purpose of IP Address Classes?
Each IP Address Class provides the following information:
► Class A: First 8 bits → NETWORK ID & remaining 24 bits → HOST ID
► Class B: First 16 bits → NETWORK ID & remaining 16 bits → HOST ID
► Class C: First 24 bits → NETWORK ID & remaining 8 bits → HOST ID
► Class D: It represents a 32-bit multicast group ID.
► Class E: It is currently not being used. (NO need)
► For example,
Let us consider the IP Address 203.43.21.12
We know that it belongs to Class C.
Therefore, the NETWORK ID is 203.43.21 and the HOST ID is 12.

One of the most asked question is Which antivirus has good strength or How to check antivirus strength?
This post is for them who want to check their antivirus strength.This is a standard test and if your antivirus passes this test then assume that its a good antivirus.
