Exporting and importing

IP Calculator lets you export calculation results and import network lists for analysis.

Exporting results

The Export button is available in the following tabs:

• Calculator — Exports the subnet enumeration table.
• VLSM — Exports the allocations and free space tables.
• Supernet — Exports the summary routes table.
• Overlap — Exports the relationships table.

Export formats

CSV

Comma-separated values, suitable for importing into spreadsheet applications or processing with scripts. Each row corresponds to a table entry.

HTML

A formatted HTML table that can be opened in a web browser or included in documentation and reports.

Importing networks

The Supernet and Overlap tabs support loading networks from external files using the Load File… button. Accepted file formats include plain text (.txt) and CSV (.csv) files, with one CIDR network per line.

This is useful when you have a large list of networks exported from a router, IPAM system, or spreadsheet and want to quickly check for summarisation opportunities or overlapping allocations.

Copying values

You can right-click on any value in the details panels (Network Details, Mask Details, Address Details, Prefix Details) to copy it to the clipboard. This makes it easy to transfer individual values such as subnet masks, wildcard masks, or CIDR notation into other applications.
