From #5 item 3:

Port state keys are ip:port with a single hostname field. If multiple hostnames resolve to the same IP (shared hosting, CDN), only one hostname is associated. When that hostname removes the IP from DNS, the port state is orphaned but the IP is still valid for other hostnames. Need a set of associated hostnames, not a single one.
