A CNAME record creates an alias for another domain name, which DNS looks up. This is useful, for example, if you point multiple CNAME records to a single A record in order to simplify DNS maintenance.
To add a CNAME record, perform the following steps:
To delete an A or CNAME record, perform the following steps:
This feature only appears if your System Administrator installs PowerDNS in either of the following interfaces:
DNS Security Extensions (DNSSEC) add a layer of security to your domains' DNS records. DNSSEC uses digital signatures and cryptographic keys to validate that DNS responses are authentic. These digital signatures protect clients from various forms of attack, such as Spoofing or a Man-in-the-Middle attack.
To enable DNSSEC for a domain, perform the following steps:
If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
Click Enable. The system will generate a new DNSSEC key, and a new line will appear that contains the following information:
|Key Tag||An integer value that identifies the domain's DNSSEC record.|
|Algorithm||The record's encrypted signature.|
|Digest Type||The algorithm type that constructs the digest. Select the Digest Type that your registrar supports.|
|Digest||An alpha-numeric string that the algorithm generates.|
After you generate the domain's DNSSEC key, you must configure a Domain Server (DS) record with your domain registrar. Click the links below for DS record instructions with some of the most popular domain registrars.
To disable DNSSEC for a domain, perform the following steps:
After you generate the domain's DNSSEC key, you must delete the DS record with your domain registrar. Click the links below for DS record instructions with some of the most popular domain registrars.
