Frequently Asked Questions
Common questions about our domain and network tools
What is a WHOIS lookup?
WHOIS is a query and response protocol used to look up information about registered domain names. It provides details like owner contact information, registration dates, expiration dates, nameservers, and registrar information.
How do I check my IP address?
Use our "What is My IP" tool at the top of this page. It automatically detects your public IPv4 and IPv6 addresses using client-side detection, along with your approximate geographic location based on your IP.
What DNS records can I lookup?
Our DNS Lookup tool supports all major record types including A (IPv4 address), AAAA (IPv6 address), MX (mail exchange), NS (nameserver), CNAME (canonical name), TXT (text records), SOA (start of authority), and more.
Why do results vary between tools?
Results may vary due to DNS caching, propagation delays, different resolver paths, and API rate limits. DNS changes typically take 24-48 hours to propagate globally.
Is my data stored when using these tools?
No. All calculations are performed locally in your browser or via temporary API calls. We do not log or store any of your queries, IP addresses, or search data.
Can I use these tools for commercial purposes?
Yes! All our tools are completely free for both personal and commercial use. There is no registration required and no usage limits.
