Shortening an IPv6 address

“

- [Instructor] One of the characteristics of an IP version 6 address is it is large. It is 128 bits in size. And we make that more manageable by using hexadecimal numbering when we're writing out an IP version 6 address. But as we saw in our last video, we're still left with 32 hexadecimal digits. To make this address even more manageable and easier to type in, there are a couple of rules that, in some cases, let us shorten an IP version 6 address. Let's take a look at those two rules. When we're looking at a quartet, which is a grouping of four hexadecimal digits, we can eliminate any leading zeros in that quartet. So if I had a quartet of 0004, I could just write a 4 for that quartet. Something else I could do is represent consecutive quartets containing all zeros with a double colon. So if I had three quartets in a row as an example and they all contain zeros, I could substitute those three all zero quartets with a…
