Host Characterization: Top-Level Domain (TLD)
47% of all infected hosts had no reverse DNS records, so we could not determine their TLDs
.COM, .NET, and .EDU are all represented in proportions equivalent to their overall share of existing hosts
136 .MIL hosts and 213 .GOV hosts also infected
390 hosts on private networks (addresses in 10.0.0.0/8) infected, suggesting that private networks were vulnerable and many more private network hosts may be infected
