This server assigns an IP-address to that client machine. These tools were originally part of the massive effort to stave off the Date of Doom, but they have proven themselves far more valuable in saving time by relieving network administrators of the burden of statically configuring IP addresses on client machines.

The Internet has been growing exponentially since 1990, as more and more organizations enter cyberspace to facilitate business, research, and education. The downside to this phenomenal success is that the Internet faces a serious shortage of IP addresses, those unique strings of binary numbers that identify Internet hosts. In the early 1990s, people predicted that the last Class B IP address would be allocated in March 1994, a month dubbed the Date of Doom. Although researchers developed interim solutions to postpone the ***DATE OF DOOM***, today it's happening all over again: All current IP addresses will be depleted sometime between 2005 and 2010, if the current rate of Internet growth continues.
