<h3>External Services</h3>
<p>This plugin connects to external services to obtain domain information and TLD validation data. These services are essential for providing accurate domain availability information and ensuring proper domain validation.</p>
<h4>IANA RDAP DNS Bootstrap Service</h4>
<ul>
<li><strong>What the service is</strong>: IANA RDAP DNS Bootstrap Service (https://data.iana.org/rdap/dns.json) – The official Internet Assigned Numbers Authority service for RDAP server discovery</li>
<li><strong>What it is used for</strong>: Primary source for obtaining the official list of TLD (Top Level Domains) and their corresponding RDAP servers</li>
<li><strong>What data is sent</strong>: No personal data is sent. The plugin downloads the public DNS bootstrap file containing TLD-to-RDAP-server mappings</li>
<li><strong>When data is sent</strong>: During TLD list updates (manual or automatic) and when validating domain extensions</li>
</ul>
<h4>RDAP Servers (Various Domain Registries)</h4>
<ul>
<li><strong>What the service is</strong>: Various RDAP servers operated by domain registries and registrars worldwide (e.g., Verisign for .com/.net, PIR for .org, etc.)</li>
<li><strong>What it is used for</strong>: Querying domain registration information and availability status using the RDAP protocol</li>
<li><strong>What data is sent</strong>: Only the domain name being queried (e.g., “example.com”). No personal or sensitive information is transmitted</li>
<li><strong>When data is sent</strong>: When users perform domain availability searches through the plugin interface</li>
</ul>
<p><strong>Important Notes</strong>:<br />
– Domain queries are cached locally to improve performance and reduce external service requests<br />
– No personal, private, or sensitive data is transmitted to these services<br />
– Only domain names and TLD information are sent for legitimate domain availability checking<br />
– All communications use secure HTTPS connections<br />
– The plugin respects rate limiting and best practices for RDAP queries<br />
– If external services are unavailable, the plugin uses cached TLD data and provides appropriate error messages</p>
