Actually, lots more than five.  E.g., NTP servers, preferred WINS  
servers (sorry, AD servers) and many other interesting (to some)  
items. And, the DNS domain my laptop joins depends on the network  
where it is connected in accordance with business policies in effect.   
Thus, DHCPv6 is of great interest for portable systems.

I have previously noted that many clever technicians are well versed  
in what we do not need - without considering all the business  
management requirements that end user systems must meet. They are all  
correct, but not right.
