It is not. I actually tested it using a random /24 in the TEST database. First, I created a /24 inetnum object with the ALLOCATED PA status, and then 255 inetnum objects with the SUB-ALLOCATED PA status - ranging from 192.0.2.0 - 192.0.2.254 down to 192.0.2.0 - 192.0.2.0. As a side note, the last one doesn't make much sense, since it's not possible to create any smaller inetnum object with ASSIGNED PA status.
That is not surprising - but I was talking "depth", not "breadth".
Same here. I was talking "depth" as well.
So the maximum depth of nesting in a /24 is 8, then you hit /32, and
My observation is that it was 1 allocation having 255 sub-allocations nested one in another. Like 192.0.2.0 - 192.0.2.0 nested in 192.0.2.0 - 192.0.2.1 nested in 192.0.2.0 - 192.0.2.2 nested ... in 192.0.2.0 - 192.0.2.254 (last, most outer sub-allocation) nested in 192.0.2.0 - 192.0.2.255 (allocation). So the maximum depth of nesting in a /24 is 255.
No :-)
Yes ;-)
192.0.2.0/24 192.0.2.0/25 192.0.2.0/26 ... 192.0.2.0/32
... this is what I called "nesting in depth", and the limit is 8.
Fine with me. But this is not what I was trying to explain. The inetnum object is not limited to bit boundaries.
Filling each level (192.0.2.0/32, 192.0.2.1/32, 192.0.2.2/32, ... .255/32) is what I called "width" - and of course, you can add hundreds of object that way, without mentioning "SUB-ALLOCATED" at all (just tag the /32s as "ASSIGNED").
Sure, but that's not what I did. These weren't /32s. Since I probably wasn't very clear, which led to the misunderstanding, let me explain one last time using a small diagram what I've done: 192.0.2.0 - 192.0.2.255 (/24 ALLOCATION) |-> 192.0.2.0 - 192.0.2.254 (255 addresses; SUB-ALLOCATION) |-> 192.0.2.0 - 192.0.2.253 (254 addresses; SUB-ALLOCATION) ... |-> 192.0.2.0 - 192.0.2.1 (2 addresses; SUB-ALLOCATION) |-> 192.0.2.0 - 192.0.2.0 (the only /32 in my example; SUB-ALLOCATION) In this scenario, there are 255 levels. Hope that's clearer now. Best, Piotr -- Piotr Strzyżewski
