IPV4 CIDR SPLIT
Split one IPv4 parent network into equal child CIDR blocks and inspect the resulting ranges. All subnet math stays in this browser.
COMMON SPLITS
The child prefix must be equal to or longer than the parent prefix. For very large split counts, the exact total is shown but only the first 256 child networks are rendered/exported to keep the browser responsive.
REFERENCE / FAQ
COMMON QUESTIONS
What does splitting a CIDR mean?
Splitting increases the prefix length to create equal smaller networks inside the original parent network.
Why does the tool limit rendered rows?
A small parent network can produce thousands or millions of children at long prefix lengths. 0bps calculates the total but renders only a bounded first set to keep the browser responsive.
Does splitting change the parent address space?
No. The child networks partition the same parent range without adding or removing addresses.
The selected child prefix must be equal to or longer than the parent prefix. Every generated subnet has the same size.
The total child count is calculated exactly, while the visible table is capped to protect browser responsiveness.
PRACTICAL / EXAMPLES
PUT THE NUMBER IN CONTEXT.
Short examples using the same units and assumptions as this module.
A /24 split to /26 creates four equal networks with 64 addresses each.
The parent contains 256 child /24 networks; the planner can export the bounded rendered set.
