Also, it is sometimes suggested you should not include .0 and .255 in 
your ranges. Believe it or not, some software developers still cannot 
grasp those as being a valid address for a device to have - everyone 
**knows** than .0 is the network and .255 the broadcast address, and 
at my last job I worked with some supposedly professional network 
people who couldn't grasp the error in that :-/

I don't know if any DHCP clients still have a problem, but I know of 
one well known manufacturer of routers (popular in the consumer 
market) that does not accept .0 or .255 as valid when configuring a 
range of addresses to allow remote management from ! The mind boggles 
when you think how long classless routing has been the norm and some 
people still don't "get it".

Must go and practice being calm for a bit ...
