IP Addresses & DNS

Question 1: What is a protocol?

A protocol is rules that machines will use in order to communicate with each other. Send and receive messages.

Question 2: What is an IP Address and how is it organized?

An IP address is like any other address but its one for your device instead of home or business. The IP address uses the numbers to communicate with other devices over the internet. An IP Address is organized in 32 bits. First will be the country or network and then sub network and then the devices.

Question 3: What is the difference between IPV4 & IPV6

The difference between IPV4 & IPV6 is that IPV4 protocol uses 32 bits for addresses which can make 4 billion different addresses but that is not enough because technology has changed the world and we need more than 4 billion so IPV6 uses 128 bits which can make 340 undecillion addresses.

Question 4: What is the difference between an IP packet and IP address?

Information is split into packets which can transfers data and and knows where it is to be sent.

Question 5: Explain DNS

DNS stands for domain name system which are separate domains so not everyone is crowding one domain there are different ones like .com/.org/and the other ones.

Question 6: My IPV4 address is 10.1.96.209.
