I added a small chunk of code to Nessus about a year ago that allows both of
these, in addition to standard CIDR-style network specifications (e.g.
192.168.0.0/16). As is my nature, I didn't get round to contributing any
documentation for the feature! ;-]

Things you can do:-

192.168.1.1-255 (scan from 192.168.1.1 to 192.168.1.255 inclusive)

192.168.1-255.1-254 (scan from 192.168.1.1 to 192.168.255.254, excluding
broadcast addresses (assuming /24), but including addresses such as
192.168.37.54)

192.168.1-255.1 (scan all hosts with final octet==1 - useful if you have a
well-structured network and all your routers, DNS servers or whatever are
always numbered .1)

Ranges can be specified for any or all octets.

Hopefully that's sufficiently lucid. ;-)

Renaud, where would be a good place for me to document this?

Hugo, perhaps you'd like to add this to the FAQ?
