# Certificate Served on an IP Address The certificate on 1.1.1.1: cloudflare-dns.com, whose Subject Alternative Name also lists IP addresses. Source: https://docs.deepinfo.com/reference/lookup/ssl/examples/ip-address/ Last updated: 2026-09-24 --- `GET https://api.deepinfo.com/v1/lookup/ssl?target=1.1.1.1` The certificate on 1.1.1.1: cloudflare-dns.com, whose Subject Alternative Name also lists IP addresses. Example 2 of 4 in **Valid Certificates** · [SSL Certificate Examples](/reference/lookup/ssl/examples/) · endpoint: [SSL](/reference/lookup/ssl/) Tags: `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`. ## Request | Parameter | In | Value | |---|---|---| | `target` | query | `1.1.1.1` | ```bash curl 'https://api.deepinfo.com/v1/lookup/ssl?target=1.1.1.1' \ -H 'apikey: YOUR_API_KEY'
