How to setup multiple A records for the same domain

I have a domain configured in DO. My k8s cluster runs in DO and I’m pretty happy with it. The landing page for my company runs in vercel.co so now I want to configure my domain to handle users accessing the webpage or the microservices behind the load balancer.

I want to have the following behavior:

GET example.com -> 72.72.21.21 (vercel.co)
GET *.example.com -> DO load balancer

My DO load balancer is a service in k8s with an ingress controller. I can dynamically create Ingress routes like api.example.com and It should send the traffic to the load balancer.

Accesing example.com should send traffic to the ip address.

Can I acomplish this with 2 A record and setting one to *.example.com or not?

This sounds like it would be configurable in a domain managed by DO. Just using the subdomain routing and setting your wildcard to your DOKS LB and your domain to the IP you mentioned.

Hope this helps!
