 #### Gateway IP
 
-For setting a specific IP address in a generated `Service`, the `.Spec.Addresses` field can be used.
+This section just clarifies and existing part of the spec, how to handle `.spec.addresses` for in-cluster implementations.
+Like all other Gateway types, this should impact the address the `Gateway` is reachable at.
+
+For implementations using a `Service`, this means the `clusterIP` or `loadBalancerIP` (depending on the `Service` type).

 This would generate a `Service` with `clusterIP` or `loadBalancerIP`, depending on the Service type.
 
-This follows the same behavior as out-of-cluster Gateway implementations.

-Note: this differs from the selection of "manual deployment", which doesn't use `IPAddress` type.
-Instead, these Gateways attach to some existing infrastructure (such as Service) which provides an address.

 This is intended to clearly identify resources associatd with a specific application, environment, or Gateway.
 Additionally, it can be used support integration with the kitchen-sync of Kubernetes extensions which rely on labels and annotations.
 
+Validation will be added to prevent any usage with `gateway.networking.k8s.io/` prefix, to avoid conflicts with `gateway.networking.k8s.io/gateway-name` or other future additions.

 #### Arbitrary Customization
 
 GEP-1867 introduces a new `infrastructure` field, which allows customization of some common configurations (version, size, etc)
