What is the difference between using the authenticated free plan and just the public API with no account?

The IPinfo public API is available without an account, but the service is limited to 1000 requests per day, and this limit is shared by everyone using the same IP address.

Registering for our free plan instantly provides unlimited requests per month with no daily limit. Your account also gives you access to your IPinfo dashboard where you can check your monthly requests, view yearly usage stats, and explore product upgrades.
