The bulk edit DNS feature lets you define and modify zone records for multiple domains in a single request. This article explains how to run a bulk DNS change in the Reseller Control Panel and describes the DNS record types you can add or modify.
Warning: There is no undo for a bulk DNS change. To correct a mistake, you must edit each affected domain individually or submit another bulk job.
Before you begin
- Enable the DNS service. The DNS service must already be enabled for each domain you want to edit. See Adding, modifying, and deleting nameservers.
Step 1: Select the domains to edit
Start in the Reseller Control Panel and choose the domains you want to apply the change to.
- Sign in to the Reseller Control Panel.
- Go to the Domains page and select the checkbox next to each domain you want to edit.
- Choose Edit DNS from the bulk actions drop-down list.
Step 2: Define the DNS change
Specify the operation and record details. The fields shown depend on the record type you select.
- Select the operation you want to perform from the DNS action drop-down list.
- Select the record type from the Record type drop-down list.
- If you are adding a record, enter the subdomain and record data. If you are modifying or removing records, select the checkbox next to each field you want to change, then complete the associated fields.
Step 3: Save the change
- Optionally, enter an address in the Email results to field to receive a change confirmation.
- Click Save DNS.
DNS record types
The table below describes the record types you can add or modify and the fields each one uses.
Record type | Description and fields |
|---|---|
A | Maps the domain name to its IPv4 address. Subdomain is the third level of the domain name, such as www or ftp. IP Address is the numeric address that computers recognize, for example 123.45.54.123. |
AAAA | Maps the domain name to its IPv6 address. Subdomain is the third level of the domain name. IPv6 Address is written as eight groups of four hexadecimal digits, for example 2001:0db8:85a3:0000:0000:8a2e:0370:7334. |
CNAME | Canonical Name. Points a subdomain to another hostname, creating an alias for your domain. Subdomain is the third level of the domain name. Hostname is the fully qualified domain name (FQDN) you want to point to. |
MX | Mail Exchange. Determines how mail is delivered to your domain so email is routed to the correct destination. Subdomain is the third level of the domain name. Priority is the preference of the target host (0 to 255, where a lower value is more preferred). Hostname is the FQDN to point to. |
SRV | Service record. Subdomain is the third level of the domain name. Hostname is the FQDN to point to. Priority is the preference of the target host (0 to 255, where a lower value is more preferred). Weight is a relative weight for records with the same priority. Port is the TCP or UDP port where the service is found. |
TXT | Text record. Attaches text to a hostname, such as SPF data to validate that email is sent from the domain's mail server. Subdomain is the third level of the domain name. Text is the content you want to include, up to 254 characters. |
DFWD (Forward) | Redirects visitors to another website you own when they type your domain name in the browser address bar. |
DFWDM (Masked Forward) | Redirects visitors to another website but keeps your domain name displayed in the address bar. |
Next steps
- Edit DNS for a single domain when you only need to change one. See Adding, modifying, and deleting nameservers.
