An extension of the great IPvFoo extension!
Display the server IP address, with a realtime summary of IPv4, IPv6, Hostname, ASN, and HTTPS information across all page elements.
For hostname information, Google's DNS (dns.google) over HTTPS is used. Over the same DNS service, Team Cymru's IP to ASN service is queried to find ASN information for IPs. They are only contacted if you press on the popup. No other 3rd party services are contacted.
The extension was originally to raise everyday awareness of the global IPv4 to IPv6 transition. Though I found it was also a useful developer tool in finding where your requests are going. So I've extended the extension.
IPvFooBarBaz's action icon shows a large red 4 or green 6 to indicate whether the outer page was fetched using IPv4 or IPv6. If the page connects to other domains, a smaller 4 or 6 appears alongside.
When you click the icon, a table appears with a row for each domain:
