Hello

I noticed that web.de uses a NSEC3 Hash Algorithm Type 8.

But 8 is not assigned:
http://www.iana.org/assignments/dnssec-nsec3-parameters/dnssec-nsec3-parameters.xhtml#dnssec-nsec3-parameters-3

; <<>> DiG 9.8.3-P1 <<>> web.de NSEC3PARAM +noall +answer
;; global options: +cmd
web.de.                 600     IN      NSEC3PARAM 8 0 333 -

; <<>> DiG 9.8.3-P1 <<>> gmx.ch NSEC3PARAM +noall +answer
;; global options: +cmd
gmx.ch.                 600     IN      NSEC3PARAM 8 0 350 -

On a related note, I'm also confused why the browser plugin from
https://www.dnssec-validator.cz/ does not recognize that gmx.ch is
DNSSEC signed. It works for web.de though!

Any idea?

Daniel
