I realize this is a bit off-topic, but it is relevant in that sometimes
when trying to set up a blacklist for a range of IP's, my WHOIS reveals
only a CIDR designation for the network I am suspicious of.

For example, 218.175.0.0/16... how do I interpret that? I have read some
of the RFC's on CIDR notation, but it still boggles my mind. Would that
mean that they own the entire range from 218.175.0.0-218.175.254.254?

Is there an easy way to read CIDR? or a tool that will do the conversion?

Thanks for any and all help.
