My IPv4 & IPv6

Why check your IP address?

Knowing your public IPv4 or IPv6 helps with remote access, VPN checks, firewall rules, and debugging. Use this IP checker to see what the internet sees when you connect. With "More details" you can load WHOIS data for your current connection (one request counts toward the tool rate limit).

Quick tips

• Dual-stack: If you only see IPv4 or IPv6, your connection or network may not support the other. Many ISPs now offer both.
• Behind a proxy or VPN? The IP shown is the one reaching our server (often the proxy or VPN exit). Turn VPN off to see your real IP.
• Private addresses (e.g. 192.168.x, fe80::) have no public WHOIS; that is normal on home or office networks.
• The User-Agent is the string your browser sends; it identifies the browser and often the OS. Servers use it for analytics or compatibility.

Things to consider

Your IP can change (dynamic vs static). For port forwarding or server access you need the current one. WHOIS reveals the registrant or allocator and is useful for abuse reports or verifying your own allocation.
