IP Cow is a fast, no-nonsense set of network tools — IP, DNS, email and RDAP lookups, SSL checks, and more. Every tool is free, forever, with no login required.
What you can do
- Run tools in the browser — head to Tools. Nothing to install, no account needed.
- Call the API — every tool has a JSON endpoint. See API → Overview.
- Create an account — for an API key, SSL-expiry monitoring, domain parking and saved preferences. Accounts are zero-knowledge; see Accounts & privacy.
Free vs. paid
The tools stay free. Paid plans add monitoring, domain parking and a higher API rate limit — see Pricing. You can always use everything anonymously within the free limits.
