 Completion" sesction below.
 
+The consumer can provide a NUL-terminated hostname in the @ta_peername
+field that is sent as part of ClientHello. If no peername is provided,
+the DNS hostname associated with the server's IP address is used instead.
+
 The consumer can fill in the @ta_timeout_ms field to force the servicing
 handshake agent to exit after a number of milliseconds. This enables the
 socket to be fully closed once both the kernel and the handshake agent
