I am new at Let’s Encrypt and I read a lot about it. Now I saw the limitations of requesting certificates. This concept is implemented over the PSL. But now I have two questions:
Why are there such limitations? Is it to prevent DoS-attacks?
And the secone one, .de is a suffix, too, right? So why is it possible to request for .de more than 20 certificates per week? For instance, a.de, b.de, c.de and so on. If I would request more than twenty certificates for ddns.net, the limit would be reached quickly.
Thanks in advance
