Do dns-addressed links guarantee content authenticity?

From @dotchev on Sun Feb 12 2017 17:16:16 GMT+0000 (UTC)

Considering that a dns link of the form /ipns/exmple.com contains no public key hash, how can we be sure of the authenticity of the content it points to?
Isn’t it a security degradation compared to normal ipns links?

If DNS takeover/spoofing is part of your threat model, yes.

We use DNS to resolve them to hash links, so if DNS service is compromised they hash link can be replaced.

@Kubuxu On that note, do you use DNSSEC validation on your gateways (to prevent such spoofing where an administrator has set it up correctly)?

Not sure, cc @lgierth

If we are not, we might want to do that.

Yeah we might want to have IPNS check DNSSEC signatures. Low priority for now, but I’ll happily support pull requests.

I think it is more of a infrastructure thing, having local resolver working with DNSSEC.
