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. -- hesketh.com/inc. v: +1(919)834-2552 f: +1(919)834-2553 w: http://hesketh.com/ Internet security and antispam hostname intelligence: http://enemieslist.com/ _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
