I have to retrieve internal ip addresses(10.X.X.X) from clients on a intranet. The intranet is built using ASP.NET C# however i'd like to implement this feature in JS if possible. Can this be done in JS? If not how would i do this in ASP.NET? Thanks in advance!

  • Possible duplicated question, http://stackoverflow.com/questions/391979/get-client-ip-using-just-javascript – lmcanavals Mar 12 '12 at 22:37
  • Doesn't look like you can get the internal IP address of the client unless the server is on the same internal network. Here is another duplicate candidate: http://stackoverflow.com/questions/102605/can-i-lookup-the-ip-address-of-a-hostname-from-javascript – Joshua Hayworth Mar 12 '12 at 22:40
  • I cant use PHP or JSON like both solutions suggest. – timvb Mar 12 '12 at 22:52

No.

Using UserHostAddress.

HttpContext.Current.Request.UserHostAddress should do the trick, on the server side.
