Let us learn how to enable dnssec cloudflare with the support of our Cloudflare support services at Bobcares.

Enable DNSSEC Cloudflare

DNSSEC adds an authentication layer to a domain’s DNS records by digitally signing them at the authoritative DNS server.

If DNSSEC is enabled for a domain, the requested webpage will not be shown if the DNS cannot be verified due to an approved DNS hop during the network path.

This safeguards users from DNS spoofing and man-in-the-middle (MITM) attacks.

When we ask a DNS provider, such as Cloudflare, for DNSSEC, they sign the DNS zone and deliver a resource records set (RRset) that includes the following:

• DNSKEY – public key that signs the RRset
• DS (delegation signer) record – DNSKEY hash

What is DNSSEC?

Before going in deep to the configuration we have to learn more about DNSSEC and why to disable it.

DNS Security Extensions (DNSSEC) provide an additional layer of authentication to DNS, preventing queries from being directed to a faked domain.

Make sure DNSSEC is off at the registrar if we are onboarding an existing domain to Cloudflare. Otherwise, when we change the nameservers, the domain would have connection issues.

why disable the DNSSEC?

When DNSSEC is enabled on a domain, the DNS provider digitally signs all of the DNS records. This operation stops others from publishing bogus DNS records on the behalf and diverting domain traffic.

Having a single set of signed records, on the other hand, precludes Cloudflare from issuing new DNS records on our behalf (as part of utilizing Cloudflare for the authoritative nameservers).

If we update the nameservers without deactivating DNSSEC, Cloudflare’s DNS records will not resolve properly.

How to enable the DNSSEC?

Cloudflare signs the zone, publishes the public signing keys, and creates the DS record when we enable DNSSEC.

1: Enable DNSSEC in Cloudflare

A: Select the account and domain from the Cloudflare dashboard.

B: Navigate to DNS > Settings.

C: Enable DNSSEC by clicking the Enable DNSSEC button.

We have access to numerous required values in the dialog to assist us in creating a DS record at the registrar.

We may retrieve this information after closing the dialog by clicking DS record on the DNSSEC card.

2: Add the DS record to the registrar

We must now add a DS record to the registrar. If the registrant does not mention Algorithm 13, Cloudflare’s recommended encryption, it may also be known as ECDSA Curve P-256 with SHA-256.

​​Other DNSSEC setup options

If we use Cloudflare as our secondary DNS provider and wish to configure DNSSEC on the secondary zone(s), we have three alternatives depending on the configuration.

Refer to Subdomain DNSSEC if we wish to configure DNSSEC on a subdomain zone.

​​​​Limitations to enable dnssec cloudflare

If the registrant does not support DNSSEC with the encryption of choice for Cloudflare (Algorithm 13), we have many options:

• Request DNSSEC with contemporary encryption from the registrant.
• Transfer the name to a new registrar that supports DNSSEC using Algorithm 13.
• Complain to ICANN about the registrar’s failure to comply.
  Contact the top-level domain if it does not support DNSSEC with Algorithm 13 (also known as ECDSA Curve P-256 with SHA-256).
