Please add known issue: OCPBUGS-22753. Description can be same as stolostron/rhacm-docs#5777.

[#hosted-cluster-dual-stack]
=== Potential DNS issues in hosted clusters configured for a dual-stack, disconnected environment

When you create a hosted cluster in a disconnected environment that uses the dual-stack network, you might encounter the following DNS-related issues:

* `CrashLoopBackOff` state in the `service-ca-operator` pod: When the pod tries to reach the Kubernetes API server through the hosted control plane, the pod cannot reach the server because the data plane proxy in the `kube-system` namespace cannot resolve the request. This issue occurs because in the HAProxy setup, the front end uses an IP address and the back end uses a DNS name that the pod cannot resolve.
* Pods stuck in `ContainerCreating` state: This issue occurs because the `openshift-service-ca-operator` cannot generate the `metrics-tls` secret that the DNS pods need for DNS resolution. As a result, the pods cannot resolve the Kubernetes API server.

To resolve those issues, configure the DNS server settings by following the guidelines in xref:../hosted_control_planes/dual_stack_dns.adoc#dual-stack-dns[Configuring DNS for a dual stack network].

Not sure what's going with the attributes in the TP table not rendering, but the issue needs to be resolved/explained before I can set this PR as good-to-merge. Thanks, @lahinson!

This attribute is not rendering in the preview. Is it being defined in a different PR that hasn't merged yet?

This attribute also is not rendering in the preview.

I think the attributes file was recently updated. I'll double-check and replace the ibmzProductName attribute with whatever the new attribute is. Thanks!

@bburt-rh The attributes are fixed now. Thanks again!

Great. Thanks, @lahinson! LGTM now. Giving it the ok-to-merge label
