#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."

Reserved Top Level #DNS Names

RFC 2606: Reserved Top Level DNS Names
To reduce the likelihood of conflict and confusion, a few top level domain names are reserved for use in private testing, as examples in documentation, and the like. In addition, a few second level domain names reserved for use as examples are documented. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.

Finally got the Pihole on 443 behind some nice valid certs. Didn't take too much effort, the longest part was getting the ports set correctly on the Pihole server so it was only listening on localhost. A little `acme.sh` `nginx` later and everything looks good.

A screenshot of the Pihole dashboard showing that it's running securely.
Proof that the certs are valid and that everything is happy with the Pihole UI.

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.
