The Internet Protocol governing internet addresses is not important because:

• Each internet address is linked to many devices, so the HTML protocol is used to make sure that content you request when you search the Word Wide Web reaches your computer.

• Since internet architecture was designed to be fault tolerant, with multiple pathways for each packet of information, individual IP are not very important.

• Actually, the Internet Protocol governing internet addresses is very important because each device is assigned an address and if protocols governing internet addresses aren't followed, information sent over the internet has little chance of reaching its intended destination.

• The Internet Protocols governing internet addresses was important under IPv4 but in the future, under IPv6, these protocols will no longer be important.

• Information isn’t sent over the Internet reliably

• Because data can be sent dynamically each bit can take the most efficient route from the server to the user
