DNSSEC is a feature of the Domain Name System (DNS) that authenticates responses to domain name lookups. It prevents attackers from manipulating or poisoning the responses to DNS requests. DNS technology was not designed with security in mind. One example of an attack on DNS infrastructure is DNS spoofing. In which case an attacker hijacks a DNS resolver’s cache, causing users who visit a website to receive an incorrect IP address and view the attacker’s malicious site instead of the one they intended.

When you activate DNSSEC, we'll generate a public-private key pair for your zone. The public key, provided as DS or DNSKEY records, should be configured with your domain provider. Our network will use the private key to sign your records during zone deployment. The end-user resolver checks these signatures against the public keys to authenticate record integrity during transfer.
DNSSEC aims to enhance user safety by verifying digital signatures after a user enters a domain name. Information can only reach the user's device when digital signatures match between the data and the Primary DNS server, ensuring connection to a legitimate website. It utilizes digital signatures and public keys to validate information, adding new records to existing DNS entries like A, CNAME, and MX. DNSKEY and RRSIG digitally sign DNS data using public-key cryptography. Each DNS zone's name server holds public and private keys. When a user queries, the server provides information signed with its private key, which the recipient opens with the public key. If information is modified, it won't open correctly, triggering an error message.
Just click the activation button in the control panel, and our system will secure the zone. You will be required only to add the DS records at the provider, and the setup will be completed.
We are using the Elliptical Curve Algorithm (ECDSA P-256) for all signatures, which is stronger and smaller than the standard RSA keys.
Keeping DNS answers as small as possible means faster speed for you! Additionally, our Anycast DNS Network provides more rapid responses from the closest location to the resolver.
No matter what day, no matter when, we provide continuous, uninterrupted network monitoring and support. Our Technical Support team is online for you 24/7 by live chat and tickets. We can migrate your zones for free, read more here.
To activate DNSSEC signing and obtain the domain DS records and DNSKEY records, you need to process the following steps:
Optional: For additional details and guidance about DNSSEC implementation, refer to the ClouDNS DNSSEC wiki page.
When you want to connect to a particular website, your browser should get the corresponding IP address. Unfortunately, there is a chance an attacker to intercept your DNS queries and place fake information. As a result, your browser will connect to a forged website where you could potentially enter personal information, like bank details.
Thanks to DNSSEC, there is an additional level of security, and your browser is able to check if the DNS data is actually correct and not changed. In addition, DNSSEC is used not only for the web but also by any other Internet service or protocol, for instance, SMTP and Voice-over- IP (VoIP).
With DNSSEC, you can protect your domain from vulnerabilities like:
Domains with enabled DNSSEC offer cryptographic security, ensuring authentic DNS data and protecting users from attacks and traffic interception. They safeguard brands from DNS hijacking and reputation damage. In contrast, domains without DNSSEC lack this protection, making them more vulnerable to attacks and putting both users and brands at risk.
Feature | DNSSEC-Enabled Domains | Non-DNSSEC Domains |
---|---|---|
Security | Cryptographically secured | Vulnerable to DNS attacks |
Trust | Verified, authentic DNS data | Unverified, prone to spoofing |
User Safety | Guaranteed traffic integrity | Risk of traffic interception |
Brand Protection | Shielded from DNS hijacking | Open to reputation damage |
DNSSEC validation is a simple process that includes the following steps:
DNSSEC can benefit anyone with an online presence, from large companies to individual website owners. It helps protect against cyber threats like DNS spoofing and cache poisoning, making it essential for businesses that rely on secure communication, such as e-commerce sites, financial institutions, government agencies, and healthcare providers. Even small businesses and personal websites can use DNSSEC to protect their data and reputation. By securing domain information, DNSSEC ensures users can trust the integrity and authenticity of a site, providing safer, more reliable online experiences for everyone.
"As a web agency we offer our clients shared hosting and we want to guarantee them that even if our server experiences any issues, their detached services would be kept running. That is why I turned to ClouDNS...
