Since HTTP 1.1, a request may contain the "Host" header: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Host which web servers can they use to serve proper content for a given host name. See, for example, http://nginx.org/en/docs/http/request_processing.html for information how nginx deals with multiple servers on the same IP address.
For https, there is SNI: https://en.wikipedia.org/wiki/Server_Name_Indication
That could explain why I can connect to my cable modem config using IP address, but not a host name & DNS. While the login screen appears either way, connections made via host name are not accepted with "Login Failed"
