Stands for “Domain Name System Security Extensions.” It is an extension of the usual domain title system (DNS), which interprets domains to IP addresses. DNSSEC improves safety by validating the authenticity of the DNS knowledge.

The unique domain title system was developed within the Nineteen Eighties with minimal safety. For instance, when a host requests an IP tackle from a title server using a normal DNS question, it assumes the title server is legitimate. However, a reputation server can faux to be one other server by spoofing (or faking) its IP tackle. A faux title server may doubtlessly redirect domains to the unsuitable web sites.

DNSSEC gives further safety by requiring authentication with a digital signature. Each question and response is “signed” using a public/personal key pair. The personal secret is generated by the host and the general public secret is generated by a DNS zone, or group of trusted servers. These servers create a sequence of belief, by which they validate one another’s public keys. Each DNSSEC-enabled title server shops its public key in a hashed “DNSKEY” DNS document.

Enabling DNSSEC

While DNSSEC will not be required for net servers or mail servers, many net hosts suggest it. To configure DNSSEC, you could use a nameserver that helps it, like PowerDNS or Knot DNS. Then you could allow DNSSEC in your server and configure it inside the management panel interface.

If you’re using a public nameserver, activating DNSSEC up could also be so simple as clicking “Enable DNSSEC.” If you’re using a customized title server, you might must manually create a number of delegation signer (DS) data. After you could have enabled DNSSEC, it might take a number of hours to activate because the server should validate the DS data with different servers inside the DNS zone.
