openssl s_client -connect ip.ad.dr.ess:443
then decode the cert

e.g.
$ openssl s_client -connect 1.2.3.4:443 < /dev/null >| cert

Now you can use the "x509" to look at various things
eg
$ openssl x509 -in cert -subject -noout
subject= /description=foobar/C=US/CN=ssl.example.com/emailAddress=foo@xxxxxxxxxxx

"man x509"
