Thanks to new directory software, Windows Vista could put a greater load on Internet servers. But experts disagree over whether we’re headed for a prime-time traffic jam or insignificant slowdown.
Microsoft’s launch of Windows Vista could slow down or stall traffic on the Net, said Paul Mockapetris, who is widely credited with inventing the Internet’s Domain Name System (DNS). Mockapetris believes Vista’s introduction will cause a surge in DNS traffic because the operating system supports two versions of the Internet Protocol, a technology standard used to send information over computer networks.
“If you adopt Vista, your DNS traffic is going to double,” Mockapetris said in an interview. It is going to try a DNS lookup for the IPv6 address and then a DNS lookup for the IPv4 address. With many DNS servers already running close to capacity, this can have serious consequences, he said. “You’re going to see brownouts. All of a sudden, it is going to be mud season on the Internet, where things will just be kind of slow and gooey.”
