Description (partial)

Symptom:
When there are multiple mDNS Service Providers using the same exact name.domain, the WLC will only keep in its database the IP Address of the last heard service provider. Therefore, clients will be unable to keep a steady connection to its service provider as the IP Address will be constantly changing. 

This can be seen with the "Google Expeditions" application. 

If different Service Providers exists with the same Domain Name in the network, the WLC will not differentiate between them and will send only the last heard IP information about the server after a client mDNS query.

Conditions:
This problem is seen when several Service Providers with the same Name.Domain exists in the network.

For example, multiple devices running the Google Expeditions app.
