Instantly find your public IP address and connection details. Useful for network troubleshooting, server configuration, and email authentication setup.
Detecting your IP address...
An IP address is a unique numerical identifier assigned to every device connected to the internet. It's like your digital home address.
Your public IP is visible to the internet and assigned by your ISP. Private IPs (like 192.168.x.x) are used within your local network.
For email, your sending IP's reputation directly impacts deliverability. Blacklisted IPs can cause emails to be rejected or marked as spam.
Pro Tip: If you run a mail server, make sure your sending IP has proper reverse DNS (PTR) configured and isn't on any blacklists. Use our Domain Health Check for comprehensive email authentication analysis.
