CentralOps.net tools

The tools at CentralOps.net are free for limited use—no login required. No ads, no CAPTCHAs, no JavaScript. Each tool is custom-crafted. Simply pick a tool and use it.

For extended and automated use you can get an account. (How to automate.)

Domain Dossier: Investigate domains and IP addresses. Get registrant information, DNS records, and more—all in one report.

Enter a domain name or IP address or learn about yourself.

Domain Check: See if a domain is available for registration.
Email Dossier: Validate and troubleshoot email addresses.
Browser Mirror: See what your browser reveals about you. This is the one tool that uses some JavaScript, just to demonstrate how it exposes you.
Ping: See if a host is reachable.
Traceroute: Trace the network path from this server to another.
NsLookup: Look up various domain resource records with this version of the classic NsLookup utility.

Whois API

Our unified Whois API provides a single, consistent, programmable interface to the Whois system. It takes your domain or IP address query, automatically contacts the correct Whois server, and returns consistent, automation-friendly results in XML or JSON.
