You are correct and McAfee is confused.
DNS root name servers that use IP anycast observed this
traffic at a significant number of anycast sites.
This implies that the botnet was widely distributed.
The source addresses of these particular queries appear to be
randomized and distributed throughout the IPv4 address space.
This says the attackers also used spoofing.
