Network Addressing

Question 1

Internet Protocol (IP Addresses)

Answer 1

An IP address is used to identify computers on the network uniquely.
Other uses of IP addresses include:
Enabling access rights
Permission management
Documenting activity (who did what)

Currently, two versions of IP addresses are used: IPv4 and IPv6. IP addresses enable communication among networks. They are also known as logical addresses because they are configured by software rather than physically embedded on the network card.

Question 2

IPv4

Answer 2

Is composed of four numbers divided by dots (.). Each number is called an octet (a collection of 8 bits or one byte), and the value of each octet can be between 0 and 255. IPv4 is a 32-bit format with a decimal value that has the following structure: 192.168.0.0

Question 3

Decimal

Answer 3

Is a numerical system composed of 10 values (Base 10) 0-9. It is the world’s most popular system for counting and calculating (for example, 1, 15, 246, and so on). Each value is represented by a Base 10 digit.

Question 4

A bit

Answer 4

(binary digit) is the smallest data unit a computer uses. It represents a logical state of 0 or 1. Based on it, the computer can perform calculations and store data. Several bits together represent a piece of data or an instruction that can be executed.

Question 5

IPv6

Answer 5

Is composed of eight hexadecimal values divided by colons (:). Each value is called a hextet. IPv6 is a 128-bit format with the following structure:
2001:0db8:0000:0042:8a2e:0370:7334

Question 6

IPv6

Answer 6

Is composed of eight hexadecimal values divided by colons (:). Each value is called a hextet. IPv6 is a 128-bit format with the following structure:
2001:0db8:0000:0042:8a2e:0370:7334
