CDNs typically work by having a CNAME record, eg.

www.realestate.com.au. IN      CNAME   www.realestate.com.au.edgesuite.net.
www.realestate.com.au.edgesuite.net. IN CNAME a1758.w7.akamai.net.
a1758.w7.akamai.net. IN      A       125.56.204.120
a1758.w7.akamai.net. IN      A       125.56.204.88

You cannot have a CNAME for zone apex records, so it can only point at an
IP address.  As a CDN customer, you generally don't want to be tied into
hard coding directly into IP address of your CDN service as such things
are fragile relationships - you control your DNS but you don't control
your CDN's DNS.
