Jamie Northern writes, "Thanks to new directory software, Windows Vista could put a greater load on Internet DNS servers. But experts disagree over whether we're headed for a prime-time traffic jam or an insignificant slowdown. Paul Mockapetris,inventor of DNS, believes Vista's introduction will cause a surge in DNS traffic because the operating system supports two versions of the Internet Protocol (IPv4 and IPv6). David Ulevitch, chief executive at OpenDNS, a provider of free DNS services, said Vista's use of IPv6 will not disrupt the Internet at large. 'DNS can be improved, but predicting its collapse is just spreading FUD.'"
