IP v6 is op komst

Een nieuwe Internet Protocol gaat eraan komen: IPv6. De belangrijkste reden voor deze update is dat de IP-adressen op beginnen te raken, aangezien de laatste tijd steeds meer mensen en bedrijven gebruik gaan maken van het internet. Behalve meer adressen zal het nieuwe protocol ook veiliger zijn dan het oude (IPv4), dat al 25 jaar wordt gebruikt. WorldCom is op dit moment IPv6 aan het testen:

The first IP overhaul in 25 years promises quality, security and zillions of badly needed addresses.

WorldCom Inc. is testing IPv6 within its own VBNS (very-high-performance Backbone Network Service). The company runs a nationwide native IPv6-over-asynchronous transfer mode section on the VBNS at speeds of 155M bps. Right now, the driving force toward IPv6 "is increased addressing space, especially as Internet-enabled devices become prevalent," said Greg Miller, director of advanced Internet technology at WorldCom, in Clinton, Miss.

Under the IPv4 specification for Internet traffic, which uses a 32-bit addressing scheme, "we're going to run out of IP addresses eventually," Miller said. The 128-bit addressing scheme of IPv6 is enough to dedicate many thousands of IP addresses for every square inch of the Earth's surface, IETF officials said.[break]Ook Sprint doet onderzoek naar IPv6. Dit bedrijf legt meer de nadruk op de betere security-mogelijkheden van het nieuwe protocol:[/break] Sprint Corp., for its part, hopes to get an early jump on the move to IPv6 through experiments with the "6bone" network -- a network put in place by industry groups to run early versions of IPv6 -- said Rob Rockell, operations engineer at Sprint's Internet Services division, in Kansas City, Mo.

Sprint is also looking to IPv6 as the vehicle for far higher levels of service security and performance, he said. For instance, IPv6 was engineered to include built-in support of QOS (Quality Of Service), DiffServ (Differentiated Services) and IPSec (IP Security). IPv4 includes none of those functions as a uniform part of the standard.
