Retrieving client IP address with Socket.io v1.0 and Express

Question

How does one retrieve the IP address of a socket.io connecting client?

This does not work in Socket.io v1.0: Get the client's IP address in socket.io . It returns undefined.

I tried doing a console.dir of the socket object, but this does not seem to work.

for long-term support, it seems that v1.0's API is slightly different from v0.9x.. v1.0's going to be released pretty soon? — jhtong, Jan 04 '14 at 12:38
I can't even get the current repo installed, so it's still in flux I guess :) — robertklep, Jan 04 '14 at 15:20
I managed to get it installed, did you miss the `http+` header in npm? — jhtong, Jan 05 '14 at 09:37
No, I got hit with a dependency on a non-released version of `engine.io`, but apparently this happened because I was using the EU mirror of the NPM repo. I have it installed now, let me see... — robertklep, Jan 05 '14 at 09:40
I was using 1.0.4 and none of the answers I found here worked. I ended up going back to 0.9.16. — LouieV, Jun 16 '14 at 19:09

How about this:

socket.request.socket.remoteAddress

uh returns undefined, even when in the `io.on 'connection'` block.. I did a `console.dir` dump and there doesnt 'seem' to be any such IP information listed. – jhtong Jan 06 '14 at 07:08
Hmm seems to work for me on the version posted on the repository. How did you install 1.0? – robertklep Jan 06 '14 at 07:32
I did the normal NPM install, from the Git repo. – jhtong Jan 06 '14 at 07:58
It returns an undefined. btw, did you test client / server codes on same machine? – jhtong Jan 06 '14 at 07:58

Yes, tried on same machine. When I try from a different machine it doesn't work for me either, but I also noticed that the transport being used is `polling`, which sounds strange. I think I would advice you to not use 1.0 until it's properly released :) – robertklep Jan 06 '14 at 08:15
I resolved to sending the IP over via a client field.. is not really crucial though if its spoofed. – jhtong Jan 06 '14 at 13:24
