In RAI, you can manage the DNS settings of domains on any customer account. Get a quick overview of the various settings and where to find them here.
Add an A record
An A record (Address record) maps a domain name to the IP address (IPv4) of the computer that's hosting the domain. An A record is used to find the IP address of a computer connected to the internet from a name.
- Under DNS settings, create a new record, for example www.example.com.
- In the left field (Hostname) type in 'www'.
- In the dropdown menu, select A.
- In the field for Address, type in the IP address, for example 127.0.0.1.
- Save the configuration.
Add a CNAME record
A Canonical Name record (abbreviated as CNAME record) is a type of resource record in the Domain Name System (DNS) used to specify when a domain name is an alias for another domain.
With a CNAME, it's possible to forward domains (and their subdomains) to the same IP address. It's also possible to create several A records using the CNAME by tying them to one A record.
- Under DNS settings, create a new record, for example www.example.com.
- In the left field (Hostname), type in 'www'.
- In the dropdown menu, select CNAME.
- In the Address field, type in the CNAME, for example cname.domain.com.
- Save the configuration.
Add a TXT record
A TXT record (short for text record) is a type of resource record in the DNS which provides the ability to associate arbitrary and unformatted text with a host name. These records are not used to direct any traffic, they provide the information to outside sources.
- Under DNS settings, enter a value in the field Hostname.
- Select TXT in the dropdown menu.
- Enter a time for TTL (default value is 3600 seconds).
- Enter a value for Priority (default value is 0).
- Enter the text you want to add in Address.
- Save the configuration.
Add an MX record
A mail exchanger record (MX record) is a type of resource record in the DNS that is used to add your own mail server. It's possible to set a value for the MX records if you have several mail servers connected to the DNS settings and want to prioritize the mail delivery.
- Under DNS settings, create a new record by typing in 'mail' in the Hostname field.
- In the dropdown menu, select CNAME.
- In the field Address, enter the CNAME, for example: mail.domain.com.cust.b.hostedemail.com.
- Add the MX record.
- Add a new MX record by typing mx.domain.com.cust.b.hostedemail.com in the address field.
- Save the configuration.
Add an SRV record
The Service Record (SRV record) is a resource record that's used to identify computers that host specific services. It's used to specify the location with a hostname and a port.
- Under DNS settings, enter a value in the field Hostname.
Use this format: _service._protocol.name - Select SRV from the dropdown.
- Enter a time for TTL (default value is 0).
- Enter a value for Priority (default value is 0).
- Enter the text you want to add in Address.
Use this format: weight port target - Save the configuration.
General format for SRV records
_service._protocol.name. TTL class SRV priority weight port target.
Format for SRV records in the DNS Settings:
- Hostname: _service._protocol.name
- TTL: numeric value set in seconds.
- Priority: numeric value.
- Address: weight port target.

Add an SPF record
The Sender Policy Framework (SPF record) is a record that identifies the mail servers that are permitted to send emails on behalf of your domain. The purpose of a SPF record is to prevent spammers from sending messages with forged From addresses at your domain.
- Under DNS settings, enter yourdomain.com in the field Hostname.
- Select TXT from the dropdown.
- Enter a time for TTL (default value is 0).
- Enter a value for Priority (default value is 0).
