    Abstract
    Der neue 128-Bit-Header treibt die Möglichkeiten ins Astronomische: 3,4 mal zehn hoch 38 Adressen, eine 3,4 mit 38 Nullen. -Das IPv6-Forum zerhackte den Zahlentrumm in anschauliche Stücke: Pro Quadratmillimeter Erdoberfläche stehen nun zirka 667 Billiarden, pro Mensch 6,5 mal zehn hoch 28 Adressen, bereit." Eine Billiarde bringt es immerhin auf respektable 15 Nullen. Schon kurz darauf ging ein Aufschrei durch die Netzgemeinde. Das neue Protokoll schrieb die weltweit eindeutigen Seriennummern bestimmter Netzwerkkarten auf den virtuellen Adressaufkleber. Die Ethernet-Adapter bewerkstelligen den Datentransport bei Computern, die über eine Standleitung, ein Koaxialkabel, dauernd online sind. Die Spur von Ethernet-Usern wäre damit leicht zu verfolgen gewesen, ihre Nutzerprofile, ihre Surfgewohnheiten einsehbar wie offene Bücher. Das Problem, ließ Icann nun wissen, sei behoben: Es gebe keine festen Kennzahlen mehr in den Adressköpfen. Bei jedem Hochfahren eines Rechners oder sogar noch öfter werden die Nummern neu durchgemischt", erläutert Hans Petter Dittler, stellvertretender Vorsitzender der deutschen Sektion der Internet Society. Das Betriebssystem Linux kann bereits mit dem IPv6 arbeiten. Microsoft will den Standard in das nächste Windows-Betriebssystem einbauen: "Wir denken, der vorgeschlagene Standard ist wichtig zum Schutz der Privatsphäre der Internet-Nutzer", sagt Jawad Khaki, Vizepräsident für Netzwerke. Seit einigen Tagen steht auf der Microsoft-Homepage eine Vorab-Version von lPv6 für Windows 2000 zum Herunterladen bereit. Geradezu euphorisch gibt sich Protokoll-Chef Vint Cerf. Mit IPv6 haben wir die Grundlage dafür", philosophierte der Internet-Daddy auf dem ersten lPv6-Kongress 1999 in Berlin, "das Internet von unserem Planeten über den Mars und die Asteroiden bis in den Weltraum hinaus auszudehnen." Doch im Internet-Alltag wird das alte Protokoll noch lange Vorrang haben. Grund sind handfeste Programmier-Probleme. Denn Software, die sich explizit auf die vierte IP-Version bezieht, muss umgeschrieben werden - etwa um mit den längeren Adressfeldern umgehen zu können. Hubert Martens vom Münchner Multinet Services befürchtet gar einen InternetCrash: "Das Jahr-2000-Problem war harmlos gegen das, was uns mit lPv6 droht."
