Ipv4 only for cloudflare proxy

Hi,

From the document https://www.cloudflare.com/ips/
Cloudflare’s IPs include ipv4 and ipv6
I want to set the trusted ips for our heroku system but the heroku doesn’t support ipv6.

So is there any way to make the Cloudflare proxy alway come from ipv4 ?

Thansk

If you only have an A record then Cloudflare will only communicate with your origin over IPv4 - since you didn’t give it an IPv6 address (AAAA record) to talk to.
