No. The answers provided by the root DNS servers are cached. So traffic
to DNS root is not at all reflective of Internet traffic in total. This
is best illustrated by the high proportion of traffic to root which is

The entire .com, .net, .au etc are not malware. You need the next level

This was once a major concern to us ISPs, together with the consequences
of a complete link failure. Australian ISPs have long used DNS
forwarders, and these caches reduce the bandwidth considerably (and,
more importantly, reduce the latency of DNS lookup, since the speed of
DNS lookup is often the major proportion of response time). Anycast
servers have solved the second issue.

In short, this is an issue which rather occupied our minds during the
1990s, but which we've worked around, and so is now mainly irrelevant.
