You connected over IPv4
Your network reached this site using IPv4. If your ISP offered IPv6, your browser would normally have preferred it.
fix Ask your ISP whether IPv6 is available, or check whether it is disabled on your router.

No reverse DNS for your address
No PTR record is published for this IP. That is normal for a residential connection, but a mail server without reverse DNS will have its messages rejected.
fix If this address sends email, ask your provider to publish a PTR record matching its hostname.
