CNAME records and A records
Contact your DNS manager (usually your Internet service provider) and ask them to set up either a CNAME record or an A record as directed on the Add Domain page.
CNAME records
CNAME records are used to assign an alias to an existing hostname in DNS.
A CNAME record might look like this:
abcdefgh.mydomain.com CNAME autodomain.mailcontrol.com.
Where CNAME indicates that you are specifying a CNAME record.
Make sure you include the trailing period in the domain name. Both the domain name and the character string are provided on the Domains screen when you add a new domain.
The above example indicates that abcdefgh.mydomain.com is forwarded to autodomain.mailcontrol.com. This enables
Forcepoint Email Security Cloud to confirm that you own mydomain.com.
A records
An A record is the Address record which maps a domain or subdomain to a valid IP address. In this case, it is matching a character string provided on the Add Domain screen. The record indicates that the specified string can be reached at the given IP address.
An A record might look like this:
abcdefgh.mydomain.com IN A 86.111.217.190
Where
IN indicates Internet
A indicates the Address record.
The above example indicates that the IP address for abcdefgh.mydomain.com is 86.111.217.190.
