Subnet Desk Pro / API (coming soon)
We are planning a paid Pro / API option for network engineers and IT teams who run the same lookups many times a day. It is not available yet. If it sounds useful, leave your email below and we will tell you when it opens.
What stays free
Nothing that is free today moves behind Pro:
- Every calculator and reference on the site, with all of its options and steps.
- Copying results, sharing a link that reopens a calculator with your values, and printing or saving as PDF.
- Your addresses stay in your browser. The free calculators never upload what you type.
What Pro / API would add
- Bulk work: paste thousands of MAC addresses for vendor lookup, or a long list of IP addresses and ranges to summarise into CIDR blocks, in one go.
- Address-plan export: a subnet or VLSM plan as a spreadsheet file to keep with your network documentation.
- A JSON API: the same subnet, CIDR and MAC vendor calculations from your own scripts. Each calculator already has a fixed input and output format, so the API would return exactly what the page shows.
There is no price yet and nothing to buy. Joining the list is free and does not commit you to anything.
Thank you — you're on the list. We'll send one email to that address when Pro / API opens. Until then, every free tool keeps working as it does today.
We will send one email when it opens and will not use your address for anything else; see the privacy policy.
