.net - To get visitors IP address -

I would like to get the visitor's IP address.

Which is appropriate to use:

  request. The server ("REMOTE_ADDR")   
 or  
  request. UserHostress   
 Which is the best way?   
 
 
 They are exactly the same  UserHostAddress  just call  GetRemoteAddress .  
  public string UserHostAddress {get {if (this._wr! = Null) {this._wr return GetRemoteAddress (); } Return tap; }} Public override string GetRemoteAddress () {return it back. GETServerVariable ("REMOTE_ADDR"); }   
 Both also. Net Framework 1.0 / 1.1 are ahead
