"the 'local_net_address' parameter is used to get the IP address of the client."

Yet from books online:

"Returns the IP address on the server that this connection targeted. Available only for connections that are using the TCP transport provider."

In other words, it returns the SERVER IP address, NOT the client IP address, which is returned by the option from the fourth option. Steve, I think you copied and pasted wrong.

Ok so this is getting silly: that's four QotDs in a row that I have wrong, and I *knew* the answer to this one! Or so I thought, perhaps I misinterpreted "IP address of the incoming connection" - I took it to be asking for the client's IP address rather than whichever of several server IP address was connected to. Ah well, perhaps tomorrow.

Good question, but I don't like the explanation - it doesn't return the client IP address, it returns the server's IP address to which the client connected.

The only reason I got this right is that only one of the four options had a valid parametername - all the others would have been uncrecognised so that null would be returned. Judging by the explanation, Steve ment to have client_net_address (but that wasn't an option).

+1

And the results are showing:

Correct answers: 31% (4)

Incorrect answers: 69% (9)

Total attempts: 13

If everything seems to be going well, you have obviously overlooked something.

That is also the only reason I got this correct. No other option was valid. But the correct answer doesn't seem correct to me. I interpreted the question to be asking for the IP of the Client and not the IP of the server that the client connected to.

Well, there was only one valid combination anyway.

Explanation currently says "This function takes an argument, and the 'local_net_address' parameter is used to get the IP address of the client." Probably needs to be fixed now too.

Good catch. Thanks and it's fixed.

As I got to the explanation when it was already corrected, I am left with nothing to complain about. Darn! 🙂

Thanks, Steve!
