>You're mixing two completely different things. DNS is just a user-friendly server name. Each DNS can be associated with one or more IP addresses. But these IP addresses must be fixed. But not vise versa - when IP address is fixed, it does not means it have DNS. DNS have nothing to the security or fixed IP addresses. Its just a representation of IP address.

Many network systems configured to allow client computers to 'obtain IP address automatically'. This means that IP address might change. In Windows 2000 it might be changed even without computer restarting. More, such IP address in many systems is local to the LAN where it used. So, when you try to access it from outside world, you cannot because tehre are no such IP address for routers or it will lead to completely another server, but not to the main server of the LAN where locally this IP address used.

I understand how DNS, DHCP, and LANs in general work. But I think we interpreted the question differently:

I took "using a hard-coded IP address instead of a domain name" to mean that the client was trying to access a resource using an IP address, and not depending on DNS to resolve it. Not that the client was trying to configure a static address for himself.
