alt Hacker NewsNicely done. I poke at DNS a bit over at StackFox (https://stackfox.co/site/wirewiki.com), and anyone who’s spent time looking at DNS knows how much work goes into this.
A couple thoughts:
1) Nameserver “redundancy” that isn’t. All the ns1/ns2 setups that collapse onto the same provider or ASN once you follow the trail.
2) Authoritative drift. One server quietly serving an older serial or odd TTL for a while — invisible until something breaks. With global data, quirks like that become obvious.
Anyway, inspiring job. Wirewiki already feels like something that should have existed but somehow didn’t.
You're the second person in these comments who points out faux name server redundancy. Interesting. I hadn't considered it as a major theme, but I'll move it up the list a little.
> Authoritative drift.
This is why I query all authoritative name servers (as well as delegating name servers when querying NS records) in the DNS propagation tool. I haven't seen any other site do this. This feels like such an obvious thing to me, but somehow I'm the only one.
