 Changes from [BEP15]_:
 
 - key is ignored
-- port is probably ignored
+- IP address is unused
+- port is probably ignored but must be same as I2CP from port
 - The options section, if present, is as defined in [BEP41]_
 
 The response MUST be sent to the I2CP "to port" that was received as the request "from port".
