netmasks

[Martin Clarke <prolix@redbrick.dcu.ie>]

a question i was asked recently on a topic that I thought
i understood untill i was asked....

Given the hypothetical subnet 136.206.16.128 and netmask 255.255.255.128,
state the valid range of IP addresses that could be assigned to hosts on
the subnet?(also another was 64.122.34.83 & netmask 255.255.255.240  :(  )

i was used to looking at plain netmasks ie 255.255.255.0(ffffff00) etc 
which I understand fine but my grasp of anything else is less than
good...

any help is appreciated..

thanks

Martin.
