this is the solution i got and it work, the only problem that it runs for 1.42 minute, and the profiler dont give me any hint to

improve...

the point is...

to be more clear, its a little bit more complicated as the print screen show :

i can put under 10.20.12.0 (subnet 24) aagain same ip 10.20.12.0 (but with subnet 30...

yes i agree! how can i do it?

Jeff Moden there is some "bug"

15.11.0.0

15.3.0.0

should be under 15.0.0.0

how do i fix it?

to be more clear this is an example of what i want to produce (the number in the square is the subnet selected)

Thanks

i want the result to be in some hierarchy (this is after each ip "," followed by depth level

10.0.0.0,0

10.13.15.63,1

10.16.8.2,1

15.0.0.0,0
