Overview
DNS (Domain Name Service) is the component of the Internet that converts human-readable domain names (for example, example.com) into computer-readable IP addresses (for example, 192.0.32.10). DNS uses zone files that reside on your server to map domain names to IP addresses.
There are several different types of records in a domain's zone file. This feature allows you to create, edit, and delete A, AAAA, CNAME (Canonical Name Record), SRV (Service Record), and TXT (Text Record) records.
Reset zone files
To reset your DNS zone files to the defaults that your hosting provider specifies, perform the following steps:
1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
2. Click more.
3. Select the Are you sure that you wish to erase all of your entries and revert to the default state? checkbox.
4. Click Reset Zone File.
Add a record
To add a record, perform the following steps:
1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
2. Select a record type:
* A — This record maps hostnames to IP addresses. A records are essential because they allow DNS servers to identify and locate your website and its various services on the Internet. Without appropriate A records, your visitors cannot access your website, FTP site, or email accounts.
* AAAA — This record maps hostnames to IPv6 addresses.
* CNAME — This 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.
* SRV — This record provides information about available services on specific ports on your server.
* TXT — This record contains text information for various services to read. For example, TXT records can specify data for the SPF (Sender Policy Framework) or DKIM (Domain Keys Mail Identifier) email authentication systems.
3. Enter the appropriate information for the record type that you select.
4. Click Add A Record.
Edit a record
To edit a record, perform the following steps:
1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
2. Click Edit next to the record that you wish to edit.
3. Change the information in the text boxes as necessary.
4. Click Edit Record to save your changes, or click cancel to discard them.
Delete a record
To delete a record, perform the following steps:
1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
2. Click Delete next to the record that you wish to remove.
3. Click Delete.
DNSSEC
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.
Enable DNSSEC
To enable DNSSEC for a domain, perform the following steps:
1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
2. Click Enable. The system will generate a new DNSSEC key, and a new line will appear that contains the following information:
Column
Description
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.
Disable DNSSEC
To disable DNSSEC for a domain, perform the following steps:
1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.
2. Click Disable.
