Not so. On the public Internet applications like Edonkey and Emule work fine without it. We run a global IP network that is not connected to the public Internet and over 90% of our customers' applications don't use any DNS. They use IP addresses directly.
Fair. If you have a small or stable enough private network that you don't need to use DNS to look up things that might be different from time to time, or to send e-mail by looking up where that mail goes, this works. I don't think it scales. And at least one person claimed not to be using DNS at all ... I suspect he just didn't know how it was priming his engine.
DNS is only a facilitator for those applications that WANT to use it. And even though most current applications want to use DNS, they usually function just fine with straight IP addresses. DNS is more of a habit, than a necessity.
So is using the decimal system rather than counting sticks. But it sure makes things doable versus insurmountable.
If the users of the Internet, collectively, decide that DNS is a bad habit, better to be avoided, then you will see more and more applications that work around the DNS. Like ICQ. Or they will only use the DNS minimally in order to root their own namespaces, like LDAP with RFC 2247.
Lots of little edge apps. No core scalability. -- Joe Yao Analex Contractor
