Everyone knows what an IP address is used for, therefore most people know what theirs is, however with the depletion of available addresses, and some changes have to be made. With IPv4, 4 billion addresses were made available with 12 digits however with IPv6 the creation of longer addresses was made possible therefore allowing for more addresses. But not everyone gets any old 12 digits; each address belongs to a certain class, ‘A’, ‘B’ or ‘C’. Some belong to class ‘C’ only because those addresses are for private use, such as home networks and can be reused (multiple devices can use the same one). And large scale companies like Amazon and Google own class ‘A’ addresses.
This is relative to the class in terms of the web. Because everyone is assigned an IP address you can actually look people up in that way. And when creating anything on the web, addresses are needed. Therefore it is handy to understand the relevance of IP addresses play because perhaps one day we might want to create something and knowledge of addresses may come in handy.
There are only a couple of things I felt were missing in the article, what happens when we run out of addresses and who will suffer from this scarcity. The article does touch on the fact that some companies have already started to convert to IPv6 but what about the average user.
