What is an IP Address?

well an IP Address or Internet Protocol Address

is a numerical Address assigned to every device participating

in a Computer Network that uses the Internet Protocol for ommunication

It’s essentially an Address similar to a house address

that’s assigned to your computer or networking device

In the same way as we have street addresses and house addresses

in the physical world, in the networking world we have what are called

network addresses and host addresses

We’ll discuss it in more detail later in the course but for now

in Windows I’m going to control panel and I am looking at my local area

to the Internet but no IPv6 connectivity

Clicking on details I can see my IPv4 Address something called

a subnet mask and something called the Default Gateway

Now we will talk more about IP Addressing later once again

but for now notice an address has been configured

on my local area connection card and typically this is either

configured in IPv4 statically as I’ve done here we have manually configured an

address or its allocated using a protocol called Dynamic Host Configuration Protocol

or DHCP by a router or a device on the network

In my example I have a little DSL router that allows me to connect

to the Internet so as you can see here I am connected to the Internet

and various devices in my network have been allocated

IP Addresses dynamically from a poll of addresses

DHCP or Dynamic Host Configuration Protocol allows a server

or a device such as your home router to dynamically allocate IP Addresses

to devices as they join the network
