Validating resources located at non public ip addresses whos dating who milo ventiglia
DNSSEC introduces a delegation signer (DS) record to allow the transfer of trust from a parent zone to a child zone.
A zone operator hashes the DNSKEY record containing the public KSK and gives it to the parent zone to publish as a DS record.
label.example.com), they would all be bundled into a single AAAA RRset.
It’s actually this full RRset that gets digitally signed, opposed to individual DNS records.
The domain name system (DNS) is the phone book of the Internet: it tells computers where to send and retrieve information.
We’ve now established trust within our zone, but DNS is a hierarchical system, and zones rarely operate independently.
The root DNS name servers help verify .com, and information published by the root is vetted by a thorough security procedure, including the Root Signing Ceremony.
DNSSEC creates a secure domain name system by adding cryptographic signatures to existing DNS records.
The KSK validates the DNSKEY record in exactly the same way as our ZSK secured the rest of our RRsets in the previous section: It signs the public ZSK (which is stored in a DNSKEY record), creating an RRSIG for the DNSKEY.
Just like the public ZSK, the name server publishes the public KSK in another DNSKEY record, which gives us the DNSKEY RRset shown above.
To enable DNSSEC, a zone operator creates digital signatures for each RRset using the private ZSK and stores them in their name server as RRSIG records.
