What is DNSSEC (DNS security extensions)?

What is DNSSEC (DNS security extensions)?

DNSSEC stands for DNS Security Extensions. It was designed many years ago as a way to cryptographically sign DNS records so that when a DNSSEC enabled resolver looks up a DNSSEC signed domain the response is mathematically guaranteed to be valid. What exactly does DNSSEC protect?

Does OpenDNS support DNSSEC?

OpenDNS does NOT support DNSSEC. they strip out RRSIG records, so dnssec local validation is not possible. I switched from OPENDNS to Google’s DNS because Google is supposed to support DNSSEC. I had some issues with Google and then switched to verisign.

Is it pointless to have DNSSEC enabled in unbound?

Its completely pointless to have dnssec enabled in unbound if your just going to use it as a forwarder and where you forward does not support dnssec.. I have seen it actually break things – this was forwarding to google DNS.

Why are RRSIG records useless when using DNSSEC?

However, these RRSIG records are useless unless DNS resolvers have a way of verifying the signatures. The zone operator also needs to make their public ZSK available by adding it to their name server in a DNSKEY record. When a DNSSEC resolver requests a particular record type (e.g., AAAA), the name server also returns the corresponding RRSIG.

Does the DNS server perform DNSSEC validation?

Additionally, if the DNS client is DNSSEC-aware, it can be configured to require that the DNS server perform DNSSEC validation. The following figure shows the validation process.

What are the conditions for using easyDNS?

No “conditions,” no fine print. easyDNS is the world’s only Domain Provider to offer you this protection. “Your servers give good worldwide coverage, and I can almost always speak to someone when I need to. I have never stumped your tech support with a difficult question.

Is it possible to run a DNS query without DNSSEC?

Yes. If a resolver is not DNSSEC-aware then it simply queries your domains in the usual fashion (it won’t set the “do” flag in the query) and the nameserver will simply reply back with the normal response records and not with the accompanying RRSigs. Everything proceeds normally (unless, of course, the reply has been forged or altered)
