2 ingresses 2 different ingress controllers but serve the same hostname.

[IdanHarel]

hi, I'm using Linode as my hosting provider, I recently reached the Loadbalancer threshold of 10K.
I thought about splitting the connection by DNS round-robin.
I created another ingress controller and another ingress handling the same URLs but associated with the new controller.
the problem:
based on the external DNS logs, I can see that it goes through the DNS names, and doesn't add the additional A record for the new Nginx controller[LB IP].
my current external DNS is as follows:
--metrics-address=:7979 --log-level=info --log-format=text --domain-filter=linode.sub.example.net --policy=upsert-only --provider=linode --registry=txt --interval=1m --txt-owner-id=prod-1 --txt-suffix=.prod-1 --source=ingress

Please Advise, thanks.
