Single Supernet CIDR mode finds the smallest single CIDR block
that covers all of the subnets you enter. CIDR Aggregation mode merges your list into the minimal set
of non-overlapping CIDR prefixes.
How to use:
Select your calculation mode at the top.
Enter each existing subnet in CIDR format (e.g., 10.0.1.0/24).
Click + Add Subnet to add more lines or remove rows manually in your form post-handler.
Hit Calculate Supernet.
In Supernet mode you’ll see the single enclosing CIDR,
its network address, mask, and host range.
In Aggregate mode you’ll get a bullet-list of
the minimal aggregated CIDR blocks.
Optionally integrate or export those results as needed.
