The question is from a part of the ipfw(8) man page. Here is my question: How do you read this: addr/masklen{num,num,...} or for a better understanding, this: 10.1.2.0/24{20,35,66,18} Let me start with what I do know about it. I know that this (10.1.2.0/24) means the entire Class C of 10.1.2.0 That I completely understand, but I can't find an explanation of how to read the {20,35,66,18} part of the example. This is probably ridiculously simple, however I can't find an explanation anywhere. For the record, I have googled, bsdforumed, mailinglisted and searched tech definition sites. The man page calls them Address Sets but no one else can define that... Thanks, Curt Micol
