DNS (the Domain Name System ) is a critical part of today’s Internet. Without it, we would have to keep massive (and always out-of-date) directories (like telephone books), where you could look up the name of some site (such as Dell’s pages about their PCs) and then find the “telephone number” (IP address) of that page, which you would then “dial” (type into your browser). This is clearly not very practical. DNS is such a complex and critical topic for both IPv4 and IPv6 that I have included a chapter just for it.
