They say that the "DNS PRO" offer has 5 million queries/month. Is that a lot? Do they enforce the limit? That's 7000/requests/hour (or 115/minute or 2/second). That's not PRO in my books.
DNS results typically get cached for at least a few minutes, and most users use ISP or public DNS servers (eg, Google, CloudFlare, etc) which only do the lookup once for many users, so your authoritative DNS server will see only a fraction of the number of web requests you actually handle. I'd guess for most sites this is probably below 1% in terms of requests per second.
I'm curios so I went to check.
