Questions about secure curves

I was looking at the output of „openssl ecparam -list_curves” and trying 
to choose a curve for the web server together with letsencrypt.

It seems, letsencrypt supports prime256v1, secp256r1, and secp384r1.

Then I found the site
I have problems mapping the openssl curves with the curve names from the 
web site, but I have the feeling that none of the choices above are safe.

Or what am I missing?

Shade and sweet water!
