Internet Protocol Address (IP Address)
A addressing system (IP address) like the postal service to send data to specific computer or device
IP address is a sequence of numbers that uniquely identifies the location of each computer or device connected to the internet
2 Types of IP addressing schemes
Internet Protocol Version 4 (IPv4)
Internet Protocol Version 6 (IPv6)
Characteristic of IPv4 Address :
Uses 32-bit address
Four groups of decimal numbers
The number of each group is between 0 and 255
Separator as period (.)
Consists of 8 bits
First three number known as Network ID
Last number known as Host ID
Structure of IPv6 address :
Have 8 groups
Consist 16 bits
Total bits is 128bits ( 8 x 16 )
Importance of IPv6
Due to growth of devices accessing the internet, the original IPv4 addresses began decreasing in availability
The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security
The benefits of IPv6
Improved traffic routing
Better security
Better support for real time
-Better optimization
Domain Name : Because lengthy IP address can be difficult to remember the internet supports domain names
A domain name is the text version of an IP address
Example : www.google.com
Contains a top-level domain (TLD)
TLD identifies the type of organization associated with the domain.
