Conclusion Page 6
As said before, DNS is one of the most least understood and most important aspects of the Internet. If it weren't for DNS names, the world of dot-coms wouldn't be known by such names as "amazon.com" but rather by numbers like, 22.214.171.124. That would lead to some very interesting stock market trading, not to mention some rather confused Internet users. Because of DNS, Internet use is easier, and therefore more attractive, for simpler users. In fact, in many cases the best way to keep a server from the general public is to not give it a domain name.
If we start using DNS as a tool instead of taking it for granted, maybe the system won't feel so much like Rodney Dangerfield after all. An understanding of BIND is one way to take the first step.
