gets a specific address all the time in the ISC dhcp server, and you 
must manually make sure any pool's range statements don't include the 
fixed-addresses in the range.

This is exactly what I was wanting to do.

The discussion resulting from this question shows me that I need a good 
reference manual so that I can learn the correct syntax.

Could you please give me an example what the statement would look like 
and could you recommend some good reference material so I could learn 
proper syntax.
