Perhaps the fact that the president thinks viruses are fake news is to
blame for some of that. Certainly, the fact that there's a telco or ISP
in Brazil for every few dozen people is also a factor. But yeah, in any
case, it's far more common for rDNS in Brazil to be nothing more than
the IP address separated by dashes followed by a domain name; useful
subdomains and other meaningful tokens are vanishingly rare for most of
it. It's the bane of my existence. It's almost like the same two people
set up rDNS for most of Brazil.
