I haven't ever tried to do multiple public IPs (I only enable caching server once inside my home network as a test), 
but it looks like from the settings window that it is possible to have more than one public IP using your cache.

When the "serve clients with public addresses: on other networks" configuration is enabled, "client configuration" 
button gives generated DNS records which were also mentioned elsewhere in this thread (_aaplcache._tcp       
259200.<dnssearchname> TXT record per network)
