Excessive "Hostname not found" in logs for Trusted IPs

[mikep11]

The server log is full of "Hostname not found" messages. The IP addresses are trusted IPs.

Recommend three possible fixes:

1: Change the "Trusted IPs" configuration from a json array to a json dict with hostname labels.

Example: "trusted_ips": {"192.168.0.15": "Alice's Computer", "172.0.0.10": "Bob's Computer", "192.168.1.0/8": "Developer Network"]

2. Add a new property "Known IPs" that is a json dict with hostname labels.

3. Both 1 and 2 (to cover ips not in trusted_ips.
