Web and technical diagnostic tools

Look up DNS records, WHOIS information and approximate IP data. Explore the available utilities and their limitations. You can also generate random passwords.

• Random password generator: Generate passwords from 8 to 64 characters using letters, numbers and symbols. Choose a length, copy the result and keep a unique password for each account.
• DNS lookup: Look up available DNS records for a domain.
• WHOIS lookup: Look up available domain registration information.
• Website speed test: Open the website performance testing tool.
• Email score: Open the email deliverability assessment tool.
• Approximate IP address location: Look up the approximate location and available network details of a public IP. Understand geolocation limits and the effect of VPNs and proxies.
• IP and DNS lookup for domains using Cloudflare: Review public DNS records and IP clues associated with a domain using Cloudflare. A historical or candidate IP does not confirm its current origin server.
• Slow website impact calculator: Model slow-loading scenarios with your ad spend, average order value and monthly sales. An illustrative estimate, not a measurement of actual losses.
• Cloud storage benchmark results: Review published cloud storage results and interpret IOPS, bandwidth and latency. Check the methodology and tested configurations before comparing.
