How to get client ip address in socket.io 2.0.3?

Question

I am currently using socket.io v2.0.3 in node.js server and can't find a way to get client's IP address.

There are numerous of tips & tricks all around stackoverflow but they are outdated and not working anymore.

Answer 1

It is in the socket.handshake

{
  headers: /* the headers sent as part of the handshake */,
  time: /* the date of creation (as string) */,
  address: /* the ip of the client */,
  xdomain: /* whether the connection is cross-domain */,
  secure: /* whether the connection is secure */,
  issued: /* the date of creation (as unix timestamp) */,
  url: /* the request URL string */,
  query: /* the query object */
}

Edit: turns it it might have changed to socket.request.connection.remoteAddress, see this link.

Edit2 : Issue could be related to Client and Server version unaligned.
