What is the real world impact of every host doing their own recursive lookups?
The popular TLD nameservers would receive a lot of traffic but the amount depends on average TTLs in the wild — metrics which hopefully someone here will be knowledgeable about.
Presumably handling the traffic is nothing compared to handling www.google.com, but the TLDs can’t afford the same scale of infra that FAANG can?
Several billion people resolving their favourite websites every 86400 seconds — it’s either a lot, or one of those things the C10k folks love to show can be handled by a Pentiun III.

- zrm 6y agoA lot of this depends on where we want to go from here, too. If you use traditional UDP DNS, it's one of those things the C10k folks love to show can be handled by a Pentium III. You could probably get a single modern server to handle more than a billion UDP DNS requests per second. But if you want to add a TLS handshake to each request and that sort of thing, not so much.
