" #DNS is a fundamental part of the Internet"

And the picture which explains DNS resolution use the current IP version (unlike most tutorials which use a 20th century version)

.lu, like most TLDs, use #anycast so there are actually hundreds of machines to serve #DNS queries.

Make sure you have a solid DNS setup because everything depends on it.

And connect to Internet exchange points.

(Note: DNS hosting at Cloudflare was working during yesterday's outage.)

Fun observation of the day:

The TTL for Google's NS records is 345600, which is 4 days. The 3, 4, 5, 6 series just seems nice.

I don't know if this is a hold-over back from when Google was a fun company doing cool things - back before they dropped the "don't be evil" motto - but I like to imagine that it is.

Since @bortzmeyer told us that he opened an issue that went unanswered for a few days, @themozzie over-engineered a home-grown solution that works for all the projects we maintain. 😅

Something that started as a small curiosity and weekend project turned into a long article with several surprises for myself (including how bad I am at time estimates). I went down quite a few rabbit holes along the way.

EDNS Client Subnet in Practice: Evaluating Public Resolver Behaviors

Testing 10 public DNS resolvers reveals several distinct patterns in how they handle EDNS Client Subnet echo and forwarding, with implications for privacy and CDN optimization.
