- lloydatkinson 5y agoWhy aren't they just called infrequently used domains then?

You could call them "infrequent" but "long-tail" is also a common description to convey a Power Law distribution: https://en.wikipedia.org/wiki/Long_tail https://en.wikipedia.org/wiki/Long_tail I think in this case about DNS caching, "long tail" is better than "infrequent". In the wikipedia graph, some of the domain lookups in yellow may be "frequent" (absolute sense) but simultaneously but much less popular (long tail) such that they don't stay in DNS lookup caches.
- lloydatkinson 5y agoDNS is essentially a cache. I've never once in my life heard of infrequently accessed cache items as "long-tail". This is definitely a dumb phrase that should be avoided.
- GauntletWizard 5y agoI've never heard them referred to as anything else, so YMMV
- jasode 5y ago>I've never once in my life heard of infrequently accessed cache items as "long-tail". The parent poster wrote "long tail _domains_" and not cache items: https://news.ycombinator.com/item?id=29036188 https://news.ycombinator.com/item?id=29036188 You also used the word "domains" when you asked about "infrequently used domains" and that's the context I was responding to. I didn't say that cache items are labeled "long tail".
