Alex,

The following site has a searchable knowledgebase for nessus:

http://www.edgeos.com

This link:
http://www.edgeos.com/nessuskb/details.php?option_id=223

says that the list needs to be either CIDR notation or a comma seperated
IPs.  The values can come from input file or be entered by hand into the
interface.  I usually use CIDR to check alot of machines, to get a look at
what's exposed on the network.
