3.1.4 IP ADDRESS AND URL
INTERNET PROTOCOL ADDRESS (IP ADDRESS)
- relies on an addressing system like the postal service to send data to a specific computer or device on the internet
- a sequence of numbers that uniquely identifies the location of each computer ir device connected to the internet or any other network
IPv4
CHARACTERISTICS
- uses a 32-bit address scheme allowing for a total of 2^32 addresses= 4294967296
- made up of four groups of decimal numbers
- the number in each group is between 0 and 255
- each group consists of 8 bits, 4 groups=32bits
- the lowest IP address : 0.0.0.0
- the highest IP address : 255.255.255.255
EXAMPLE
- 1.2.3.4, 10.10.100.99, 255.255.255.255
STUCTURE
has two part:
- The network ID ( first three numbers ) identifies the network
- The host ID ( last number ) identifies the specific computer
IPv6
CHARACTERISTIC
- uses a 128-bit address scheme allowing for a total 2^128
STRUCTURE
- each IPv6 address is represented as eight groups/fields of four hexadecimal digits, separated by colons (:)
- each group consists of 16 bits
- number in each group is between 0000 to FFFF
- total bits are 8 x 16=128bits
EXAMPLES
- 2001:0db8:0a0b:12f0:0000:0000:0000:0005
- 2021:0db8:0:0:1319:8a2e:0370:57ab
BENEFITS
- larger IP address space that provide enough address space for many decades to come
- improve traffic routing
- better security
- better support for real time
- includes plug and play
- better optimization
DOMAIN NAME
- lengthy IP address can be difficult to remember, the internet supports domain names
- text version of an IP address
- a part of the web address that user type in a browser’s address bar to access a website
-eg: www.google.com
- every domain name contains a top-level domain ( TLD ), the last section of the domain name
TOP-LEVEL DOMAIN NAME ( TLD )
- identifies the type of organization associated with the domain
EXAMPLES
- .com- Commercial organizations or companies
- .gov- Government agencies
- . org- Nonprofit organizations
COUNTRY CODE TOP-LEVEL-DOMAIN (ccTLD )
- for websites outside the United State, the domain name may include a country code TLD ( ccTLD ) which is a two letter country code
- identifies the country of origin associated with the domain
- i.e., www.philips.com.my is the main domain name for Philips Malaysia
DOMAIN NAME SYSTEM ( DNS )
- method that internet uses to store domain names and their corresponding IP address
- translates the domain name to its asscoiated IP address so that the request can be routed to the correct computer
- a server on the internet that usually assiciated with an ISP
WEB ADDRESS
- a uniques address for a web page
- also called a Uniform Resource Locator ( URL )
COMPONENTS
i ) Protocol
-a set of rules that defines how pages transfer on the internetTYPES
ii ) Domain Name
- address of the computer that contains the web site ( IP address )
iii ) Path
- directories or folders that contains the files being accessed
iv ) Web Page Name
- the name of the file that being accessed
-
