The proxycheck.io API This Plugin can be used without a proxycheck.io API key, but it will be limited to 100 daily queries to the API. To enhance the capabilities, you can obtain a free API key from proxycheck.io, which allows for 1,000 free daily queries, making it suitable for small WordPress sites. Here's an overview of the free and paid API options:

• Without an API key (100 queries/day)
• With a free API key (1,000 queries/day - ideal for small sites)
• With a paid API key (10,000 to over 10 million queries/day)

Your API key can be used across all of your sites and apps, you only need a proxycheck.io plan that fits your overall needs. User IP Logging Feature Proxy & VPN Blocker allows for local logging of user registration IP addresses. The IP addresses are displayed next to each user in the Users list and on their profile pages, visible to administrators. The Plugin also logs the most recent login IP address for each user, which is also displayed in the User's list and profile page, with the IP address linked to the proxycheck.io Threats page. Caching Plugin Notice If you're using caching plugins (like WP Rocket or WP Super Cache), IP-based page blocking might not function correctly due to static caching. A DONOTCACHEPAGE option is available to help mitigate this issue. Privacy & GDPR Compliance To check IP addresses, the plugin sends them to the proxycheck.io API. No personally identifiable information (PII) beyond the IP is transmitted. For details, refer to proxycheck.io’s privacy notice and GDPR Compliance for further information. Disclaimer This Plugin is not developed by proxycheck.io despite being recommended by them.
