Hmmm.
My problem is not really that I want a range of addresses, but rather a
few different ones (although in the same subnet ofcourse). 
Currently one of our servers has
xx.xx.xx.101/26 
xx.xx.xx.111/26 
xx.xx.xx.112/26 
xx.xx.xx.139/26 
xx.xx.xx.145/26

But I guess I can make a  ifcfg-eth0-range0 with the first single address, 
...range1 with the next and so on.


Thank you for the tip.


Rgds.
