  - ### SNI_HOST_NAME

    public static final int SNI_HOST_NAME
    The "host_name" type representing of a DNS hostname (see `SNIHostName`) in a Server Name Indication (SNI) extension.

    The SNI extension is a feature that extends the SSL/TLS protocols to indicate what server name the client is attempting to connect to during handshaking. See section 3, "Server Name Indication", of TLS Extensions (RFC 6066).

    The value of this constant is 0.
