Huh. Haven’t seen DNSViz broken before.
Anyone else having issues? Seems like it’s not doing DNS queries so new analysis is impossible. :(

#DNS root servers on an observed June 2026 traffic increase:
"[...] a representative from the AS responded on July 3rd. They confirmed that the traffic originated from their networks (i.e., was not spoofed) and was the unintentional result of recent recursive resolver software updates."

RE: #DNS, #ENUM and #VoIP … and also why you need to not let domains expire….
(“Oh, we stopped using that service, right? So we can just not renew those domain names, correct?” 🤦‍♂️ Or more likely… people moved on and absolutely no one even *thought* about the domain names..)

I just released ptrclassify is a small, dependency-free Python library and CLI that infers likely IP usage from reverse-DNS PTR hostnames.
It is intentionally heuristic and multi-label. PTR naming is operator-controlled and is not authoritative evidence of how an address is actually used. The output therefore includes a confidence score, the text that matched, and the rule IDs that produced each label.
To summarize, the library is trying to guess usage (and a bit location) of an IP address based on its PTR records. It's based on a set of rules which can be updated easily.
