ves la referencia, buscas la funcion cual descripcion te parezca apropiada (ya te dije cuales eran, te adelanté ese paso), haces click en ella, buscas la version de la funcion que se adapte a lo que quieres, haces click... allí tienes ejemplos... aunque sea revisa el link, que te lo di, me dices podría seleccionar que mostrar en el msgbox, pero no tengo claridad del como
me dan una mano amigos por favor sin embargo no haces el esfuerzo por aprender... y este foro es para eso... por eso te pasé una referencia...

El problema con la sociedad actualmente radica en que todos creen que tienen el derecho de tener una opinión, y que esa opinión sea validada por todos, cuando lo correcto es que todos tengan derecho a una opinión, siempre y cuando esa opinión pueda ser ignorada, cuestionada, e incluso ser sujeta a burla, particularmente cuando no tiene sentido alguno.

HOLA!!! Perdon por llegar tarde  Pero aca tenes una funcion completisima para obtener la ip externa, copia y pega el texto en un form vacio y voila, tu ip. Esta funcion busca en varias webs tu posible ip externo y verifica que sea un ip valido. Private Declare Function InternetOpen Lib "wininet.dll" Alias "InternetOpenA" (ByVal sAgent As String, ByVal lAccessType As Long, ByVal sProxyName As String, ByVal sProxyBypass As String, ByVal lFlags As Long) As Long Private Declare Function InternetOpenUrl Lib "wininet.dll" Alias "InternetOpenUrlA" (ByVal hInternetSession As Long, ByVal sURL As String, ByVal sHeaders As String, ByVal lHeadersLength As Long, ByVal lFlags As Long, ByVal lContext As Long) As Long Private Declare Function InternetReadFile Lib "wininet.dll" (ByVal hFile As Long, ByVal sBuffer As String, ByVal lNumBytesToRead As Long, lNumberOfBytesRead As Long) As Integer Private Declare Function InternetCloseHandle Lib "wininet.dll" (ByVal hInet As Long) As Integer Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hWnd As Long, ByVal lpszOp As String, ByVal lpszFile As String, ByVal lpszParams As String, ByVal LpszDir As String, ByVal FsShowCmd As Long) As Long Private Const IF_FROM_CACHE = &H1000000 Private Const IF_MAKE_PERSISTENT = &H2000000 Private Const IF_NO_CACHE_WRITE = &H4000000 Private Const Webs As String = "http://bot.whatismyipaddress.com/ http://myip.dnsomatic.com/ http://ip.nfriedly.com/text" Private Const BUFFER_LEN = 256 Public Function Gurl(sURL As String) As String Dim sBuffer As String * BUFFER_LEN, iResult As Integer, sData As String Dim hInternet As Long, hSession As Long, lReturn As Long hSession = InternetOpen("vb wininet", 1, vbNullString, vbNullString, 0) If hSession Then hInternet = InternetOpenUrl(hSession, sURL, vbNullString, 0, IF_NO_CACHE_WRITE, 0) If hInternet Then iResult = InternetReadFile(hInternet, sBuffer, BUFFER_LEN, lReturn) sData = sBuffer Do While lReturn <> 0 iResult = InternetReadFile(hInternet, sBuffer, BUFFER_LEN, lReturn) sData = sData + Mid(sBuffer, 1, lReturn) Loop End If iResult = InternetCloseHandle(hInternet) Gurl = Replace(sData, Chr(0), vbNullString) End Function Private Function CheckExternalIp() As String Dim IP As String Dim URLs() As String: URLs = Split(Webs) For x = 0 To UBound(URLs) IP = Gurl(URLs(x)) If IsValidIp(IP) Then Exit For Next If IP = vbNullString Then MsgBox "Checkee su conexion a internet por favor, parece que esta fallando.", vbCritical, "Ups!": Unload Me CheckExternalIp = IP End Function Private Function IsValidIp(strIpAddress) As Boolean Dim aTmp IsValidIp = False aTmp = Split(strIpAddress, ".")
