That would mean that you have quite a bit of bandwidth to spare. And
a dual-processor PC server wouldn't cut it as a root server during a
traffic upswing.
The F root server, for example, until sometime last year was (as I
recall) actually a pair of dual-processor servers using UltraSparc
II's behind a load balancing DNS proxy server, connected to something
like 30 Mbit of bandwidth. And they were using it.
Then some bored teenager tried to knock the root servers off the
Internet with a DDOS attack. Only the A and F servers survived - the
rest were overwhelmed with traffic and thus rendered useless. So now
Paul Vixie, who runs the F server, is setting up a massive,
distributed array of servers to act as the F server, using shared
unicast (a fun trick with BGP).
Of course, due to the exponential growth of the Internet a few years
ago, the generic TLD's (com, net, org, etc.) were moved off of the
root servers. They pretty much just host the root zone itself. The
authoritative servers for com and net (the so-called gTLD servers)
receive quite a bit more traffic than the root servers.
