Choose Your Tool
Each tool is purpose-built for a specific network diagnostic task. Click any card to open the tool.
Find My IP Address
Instantly see your public IPv4 and IPv6 address, your ISP name, and estimated location. Useful for VPN verification, remote access setup, and troubleshooting.
WHOIS Lookup
Look up the full registration record for any domain — who owns it, when it was registered, when it expires, and which registrar manages it.
Domain Checker
Check whether a domain name is available to register across multiple TLDs (.com, .net, .org, .io, and more) in real time before you commit.
DNS Lookup
Query DNS records for any domain — A, AAAA, MX, TXT, CNAME, NS, and more. Essential for verifying email setups, SSL configurations, and domain propagation.
Real-World Use Cases
Verify Your VPN
After connecting to a VPN, use Find My IP to confirm your IP has changed and the location shown is the VPN server, not your real location.
Research a Domain Before Buying
Before purchasing a domain, run WHOIS to check if it's owned, when it expires, and whether it's available to acquire or will drop soon.
Debug Email Delivery
Use DNS Lookup to verify SPF, DKIM, and DMARC TXT records — the most common cause of emails landing in spam folders.
Check DNS Propagation
After updating nameservers or DNS records, use DNS Lookup to verify that your changes have propagated to the public DNS system.
Launch a New Website
Use Domain Checker to find the perfect available domain, then WHOIS to ensure similar domains aren't trademarked or already taken.
Investigate Suspicious Domains
Security researchers and admins use WHOIS and DNS Lookup to investigate domain ownership and infrastructure behind questionable websites.

Frequently Asked Questions
What is my public IP address?↓
Your public IP is the address assigned to you by your ISP that identifies your network on the internet. It's different from your local/private IP (like 192.168.x.x). Use our Find My IP tool to see it instantly.
Are WHOIS results always accurate?↓
WHOIS data is pulled from official registrar databases and is generally accurate, but some registrants use privacy protection services that hide personal details and replace them with proxy information.
How long does DNS propagation take?↓
DNS changes can take anywhere from a few minutes to 48 hours to propagate globally, depending on TTL (Time To Live) settings. Use our DNS Lookup tool to check the current live records.
Can I check if a domain is available to buy?↓
Yes — our Domain Checker queries multiple TLDs (.com, .net, .org, .io, etc.) simultaneously and tells you which are available for registration right now.
