Cloudflare DNS and purge item
So when you are developing things that use 'ingress' on the cloud, you often end up cycling through new IP addresses to the same domain name.
Sometimes I put the name in /etc/hosts, then I can edit it. Sometimes I put it in domains.google.com, and use a low TTL. But I've found since switching to cloudflare (18.104.22.168) that the time to propagate can be long. There has to be a better way.
Well, there is. Check out the purge-cache service. Type the domain name, select the record type, boom, its gone.
