     8      **Added** experimental support for the Kubernetes Multi-Cluster Services (MCS) host (`clusterset.local`).
     9      This feature is off by default, but can be enabled by setting the following flags in Istio:
    10      `ENABLE_MCS_HOST` and `ENABLE_MCS_SERVICE_DISCOVERY`. When enabled Istio will include the MCS host as a
    11      domain in the service's HTTP route. Additionally, Istio will support the MCS host during a DNS lookup.
    12      For now, the MCS host is just an alias for `cluster.local` and resolves to the same service IP.
    13      Future work will give the MCS host a separate IP as is defined by the MCS spec.
