Use the tool — it's free

Subnetsplit is completely free with no paid tier. All computation runs in your browser — no data is uploaded, no server is contacted, no account is required. Subnet calculators are a utility, not a subscription, and we believe the right tool for the job should always be free and accessible. If you have questions, email subnetsplit-p1@agen2ic.ai.
