The certificate "Common Name" is: dns.cloudflare.com.
There is a certificate extension - Certificate Subject Alternative Name that lists the following:
DNS Name: *.dns.cloudflare.com
DNS Name: dns.cloudflare.com
IP Address: 1.1.1.1
IP Address: 1.0.0.1
Most likely the extension was included as part of the certificate signing request.
- prdonahue 9y agoMost CAs ignore the subjectAltName extension when parsing CSRs (as it's a pain[1] for users to generate one properly). They just extract the public key, CN, and let you fill in SANs. 1 - Before Cloudflare I used to do this with OpenSSL and it requires half a dozen steps, but with cfssl you can do this quite easily: https://github.com/cloudflare/cfssl/wiki/Creating-a-new-CSR https://github.com/cloudflare/cfssl/wiki/Creating-a-new-CSR.
- silverwind 9y agoYou can generate SAN CSRs with a openssl one-liner, not that hard.
