Looking at each /24 for DNS traffic seen in the last 30 days, I see multiple connected VPS hosting services (ie, run one until it gets too hot, shut it down, spin a new one up with a slightly different name, rinse and repeat). Also dominated by gaming server rentals, and what may be live TV pirating, with a chunk of dynamic DNS indicators.
Does not look like a good neighborhood. While risk scores are low-moderate, it looks like this is almost exclusively what this ASN does; a few hundred records per /24, rather than the thousands or tens of thousands Iād expect to see with a conventional host.
