Paul Mokapetris (Paul Mockapetris), whose efforts in 1983 created the DNS system, is confident that with the release of the new Windows Vista operating system, the load on the DNS servers will seriously increase. The fact is that the new OS supports two versions of the Internet Protocol: IPv4 and IPv6.
Thus, after the ubiquitous transition to Vista, the number of requests will double. But the DNS servers are already struggling to handle the load and are working at the limit of their capabilities. According to Mokapetris, the consequences will be very serious: “This will be a dirty era for the Internet, where everything will start to slow down and get stuck,” said Mokapetris in
an interview with CNet .
Microsoft has already made a statement in which it refutes the forecast of the inventor of the DNS. They say that traffic will increase, but not twice. Other experts support Microsoft and say that Mokaptris’s point of view is closely related to his current place of work. He holds one of the honorary positions at
Nominum , which specializes in the production of communications equipment for corporate DNS servers.
So, David Ulevich, director of
OpenDNS, is sure that nothing threatens the DNS system, although it would not hurt to improve it.

However, some researchers still support Mokapetris and agree that the flow of DNS queries will increase after the release of the Vista operating system. But because of these requests can not happen. "Fan-off" DNS servers, as predicted by Mokapetris.
Windows Vista is the first Windows operating system to support the new generation IPv6 Internet Protocol. Naturally, the program also retains support for the old IPv4 protocol, which has not yet become obsolete. As a result, a computer running Vista can send two queries to the DNS server instead of one. First, it will search for an entry using the IPv6 protocol, and if no match is found, then it will follow the IPv4 protocol. However, not every computer will be able to generate IPv6 requests, but only one that has an IPv6 address.
One way or another, the flow of DNS queries will indeed increase, so the current server load level will need to be monitored very closely. For example, if in a large organization 50 thousand users switch to Vista on one day, then a corporate DNS server can really get into trouble.
