What DNSSEC signs

DNSSEC signs DNS records so a resolver can detect a forged answer. It does not encrypt the lookup, and it does not choose which resolver to trust.

The short version

DNSSEC signs DNS records so a resolver can detect a forged answer. It does not encrypt the lookup, and it does not choose which resolver to trust.

What happened

DNSSEC is a standing subject on the Networking desk. DNSSEC signs DNS records so a resolver can detect a forged answer. It does not encrypt the lookup, and it does not choose which resolver to trust. The page keeps that sentence so a trend headline does not have to. A reader who arrived from a wire line can use the sources instead of the headline. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates. The sources for DNSSEC are listed below and are the place a quote should be verified.Futureweb.

The record

The record for DNSSEC is RFC 4033. A zone that is unsigned gives the resolver no signature to check. A validating resolver then has nothing to reject. Futureweb files the distinction here and leaves the source documents in the box, linked, rather than pasted. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates. The sources for DNSSEC are listed below and are the place a quote should be verified. A wire headline about DNSSEC can be the reason a reader arrived. It is not the definition.

The document

The document to open for DNSSEC is RFC 4033. DNSSEC signs DNS records so a resolver can detect a forged answer. It does not encrypt the lookup, and it does not choose which resolver to trust. A second page that repeats a vendor adjective without this document has not added a fact. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates. The sources for DNSSEC are listed below and are the place a quote should be verified. A wire headline about DNSSEC can be the reason a reader arrived. It is not the definition.

Why it matters on this desk

On the Networking desk, DNSSEC matters because a reader has a check they can perform. A reader asks whether the zone is signed and whether their resolver validates. The desk files the check. It does not file a slogan in place of the check. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates.

What a reader can check

A reader asks whether the zone is signed and whether their resolver validates. That is the check for DNSSEC. A zone that is unsigned gives the resolver no signature to check. A validating resolver then has nothing to reject. If the check cannot be done from the documents, the page is ahead of the record and should say so. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates.

Where accounts differ

Accounts of DNSSEC differ when one source states DNSSEC signs DNS records so a resolver can detect a forged answer. It does not encrypt the lookup, and it does not choose which resolver to trust. and another skips the condition. A zone that is unsigned gives the resolver no signature to check. A validating resolver then has nothing to reject. This page does not average those accounts into a third claim neither document made. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates.

What to watch next

What to watch for DNSSEC is a revision of RFC 4033, or a shipping change that makes A zone that is unsigned gives the resolver no signature to check. A validating resolver then has nothing to reject. either more common or impossible. The URL stays. The text changes when the document changes. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates.

It is not the definition.memory safety in the release notes.

What would change this page

This page on DNSSEC would change if RFC 4033 redefined the term, or if a measurement showed A zone that is unsigned gives the resolver no signature to check. A validating resolver then has nothing to reject. was the wrong failure. Until then the definition above is the one the desk will quote. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates.

What is still specific

What stays specific to DNSSEC is the pair of facts in the opening: DNSSEC signs DNS records so a resolver can detect a forged answer. It does not encrypt the lookup, and it does not choose which resolver to trust. A reader asks whether the zone is signed and whether their resolver validates. Neighboring pages on the Networking desk answer a different question and should not be merged into this one. DNSSEC is named again here so the check is hard to miss: A reader asks whether the zone is signed and whether their resolver validates.
