Expand ranges into IP lists with sampling control.
Avoid overly large lists by sampling or setting limits.
This page expands a CIDR block into individual IP values without changing the current form, limits, or export controls. It is useful when a script, inventory, or allowlist needs explicit addresses instead of prefix notation.
Enter a CIDR block, choose whether you want a full list, a sample, or only the first and last values, then set a maximum output size.
The tool calculates the address span inside the CIDR, then generates addresses according to the chosen mode and export format.
Expand 192.0.2.0/28 to generate the full set of addresses in that block, or switch to a sampled mode if you only need representative values for testing.
Use CIDR expansion for inventory exports, scripting, scanning plans, and any workflow that needs explicit IP values.
Large prefixes can produce very large outputs. Sampling and maximum item settings are important for practical use.
It expands a CIDR block into individual addresses or a sampled subset, depending on the output mode you choose.
It is useful for inventory, allowlists, scripts, testing, and batch operations that need explicit host values.
Large prefixes can contain very large numbers of addresses, so practical export and sampling limits still matter.
Inspect subnet boundaries before expanding them.
Review IPv6 prefix details before generating address lists.
