I know it's bad practice, but i experiment with snort in undefined for
me network (i have only ip range). Unfortunately, i can not scan or do
other  active things.
So, for first  step, i decide init all available rules  and   suppress 
the ones that give a lot of false positives. 

For next step i plan use passive "scanner" like p0f (and other) do
determine home net structure  and tune snort rules.
