IP Address
All telephones connected to the Telephone
network has a number
 All computers when connected to the
Internet will have a numeric address

 Called: IP Address
 ipconfig –all, ipconfig /release, ipconfig /flushdns

Two types of IP address
 IPV4: 4 part IP address. Each part 0 to 128
○ 123.456.34.56
 IPV6: 6 part IP address
Domain Name System (DNS)

Web-sites are located in a computer in
the internet [the computer has an IP
address]
 We can access that web-site using that IP
address
 If you know the IP address of yahoo.com
web-site then in IE if you type that address,
you will see yahoo.com website
 But remebering the numeric address of a
web-site/computer is difficult. So
Domain Name System (DNS)

we have assigned a name to each website
○ However, the computer and the internet works
with the IP address internally
○ So there is a conversion from name to IP; and
then works happen with IP address
 Ping yahoo.com
 Tracert google.com, tracert justetc.net

The service in the Internet that provides
this facility is called DNS
Domain Name
The name of the web-sites are called
domain names
 The name of the computers hosting the
web-sites are called domain names
