Quite useful, good to know where the domain has it server as well the IP Adress. Handy for aplications that requier those informations like linking with the mail in some emails.

Great.

Thank you.
Here's the golden ideas:
Would love quick popup with "Geotool" and/or "My info". With a flag.
Would love to see my IP address / ISP in the tooltip.
Would love to see website certificate (especially expiration) in the tooltip.
In the server info, there could be referrer or any tracking info.

Would love ping from user network tho likely impossible.

Well done.

As a Chinese, it can help me get a faster Internet speed when paired with a VPN.
