CNAME and Domain Glossary


A Record

An A Record is similar to a CNAME but is used to map to an IP address if your website's IP address is fixed and stable. Your hosting provider can provide you with an A record and configure the IP address for you.

Unbounce uses dynamic IP addresses, so A records alone will not connect a domain with Unbounce.

You may add an A record to your domain to create a naked domain, meaning you would still need to add a CNAME record.
