Hvordan finder jeg min eksterne IP Adresse?

<td><SPAN class=\"contentbold\">Din globale IP-adresse:</SPAN></td>
                <td align=\"right\"><SPAN class=\"content\"></span></td>

Burde virke...

sjh ... tak for det, MEN den retunere blot min interne adresse ganske som Winsock kontrollen også gør ... det er jeg i og for sig ligeglad med :). Jeg skal bruge den eksterne ip adresse, dvs. ikke den der \"bare\" identificere mig på et LAN.

henrikudsen >>Er det \"255.255.255.255\" du vil eller er det \"p000-000.ppp.get2net.dk\" du vil have eller hvad.

Det er \"255.255.255.255\" :)

henrikudsen >>Hvis jeg bruger koden \"GetIPAddress()\" og går ind på \"www.myip.dk\" og ser så står den samme ip-adresse der.????????? :-)

Weird, det gør jeg ikke her?! Men så må der jo være noget helt andet galt ... tak for hjælpen om ikke andet :)

henrikudsen >> Jeg fandt lige en ny løsing til dig.

\'Download 100 byte og tag det der står i \"<title>Your IP: 255.255.255.255</title>\". ;)
