Looks like it's the glue records that point to the actual server?
Netnod.se uses a DNSKEY that is too small on their main domain.
Rcodezero.at might indeed be something. Thanks.
We donate to deSEC, so it’s not free for us.
Interesting, could you expand on that ?
I ran netnod.se through the Verisign[1] and internet.nl[2] and it passes DNSSEC tests ?

Internet.nl does not look at DNSSEC that extensively, allowing poorer quality configurations to pass. You can see what they check in the explanations of both DNSSEC metrics [4]. See [5] for discussions about keylength.
Verisign does check for key validity but not for key strength / length as seen in your link.
