How to force DNS lookup and not use caching Windows 10 desktop

I have some public IPs that keep changing and I want Windows 10 desktop to not trust its caching and to do a fresh lookup every transaction. What's the mojo? Thanks!

It's a vendor - let's call them autofoo. api.autofoo.com resolves to three public IPs say 66.1.1.1. 67.1.1.1 68.1.1.1  But the problem is autofoo keeps changing those IP addresses and our autofoo automation process breaks. We tried adding a host record and eventually that broke when they changed the IP. I'm not sure I have the pull to get autofoo to stop the nonsense.

If you don't talk to autofoo's other customers and choose another vendor.  If they lose enough customers over this, they'll change.  Or go out of business.

Pretty much the same answer I gave... Most likely the host is using round robin DNS improperly, or whatever they are load balancing isn't keeping in sync...

There is one other possibility.  Your ISP DNS server may not be handling TTL properly.  You can try bypassing it by using a different server like
    Cloudflare: 1.1.1.1
    Google Public DNS: 8.8.8.8
    OpenDNS: 208.67.222.222
