CNAME vs A records
When you connect your site to FlyingProxy, you'll get two types of records, "A" and "CNAME", like below:
Here are the differences between each:
"A" records are IP addresses. The IP address provided by FlyingProxy has dedicated IP addresses. In case the IP changes (very rare), we'll contact you and you'll have to update the IPs immediately.
CNAME records are domains which point to another IP(s). When you use CNAME records in FlyingProxy, the corresponding IPs are managed by us and you don't have to worry about anything.
So in general using a CNAME record is safer.
