What does my IP address mean?
Public vs private IP
Devices on your home or office network often use private addresses such as 192.168.x.x. Your router or ISP translates that to a public IP — the one shown above — which the rest of the internet uses to reach your connection.
Why websites ask for it
Services use your public IP for routing, abuse prevention, geo assumptions, and security logging. It is normal for a site to see it; what matters is how your organization protects exposed services and accounts behind that address.
IPv4 and IPv6
You may see a classic IPv4 address (four numbers) or a longer IPv6 address. Many networks support both. The value above is the address used for this request to ReefSecure.

Your public address is only the start. Sonar reviews your external posture — email authentication, open services, DNS, and more — while Mailsec helps protect inboxes from phishing and spoofing.
