SSL Certificate Examples · Example 2 of 4 in Valid Certificates

Certificate Served on an IP Address

GEThttps://api.deepinfo.com/v1/lookup/ssl

The certificate on 1.1.1.1: cloudflare-dns.com, whose Subject Alternative Name also lists IP addresses.

Param: target
Value: 1.1.1.1

Asks for the certificate on the IP address 1.1.1.1 (target takes a domain or an IP).

The certificate is issued to cloudflare-dns.com (Cloudflare, Inc.) by an SSL.com ECC intermediate, valid for about a year. Its Subject Alternative Name lists names and IP addresses (1.1.1.1, 1.0.0.1, IPv6 addresses); the response is shortened to the first 10. fqdn_list keeps only host names: cloudflare-dns.com and one.one.one.one.
