Standard WordPress plugin version of the original WPCode DNS bulk lookup snippet in html.html, upgraded with multi-column DNS and server health checks.

Usage

Install the plugin folder in WordPress and add this shortcode to a post, page, or template:

[dps_dns_lookup]

Optional attributes:

[dps_dns_lookup limit="100" delay="120" title="Tra Cứu DNS Hàng Loạt"]

What Changed From The Snippet

• Large inline WPCode HTML/JS was converted into a WordPress plugin.
• CSS and JavaScript are enqueued as static assets.
• DNS lookups go through a WordPress REST endpoint.
• DNS, HTTP, and SSL checks go through a WordPress REST endpoint.
• Results are cached with transients.
• Admin settings control HTTP/SSL availability, rate limits, allow/block lists, and optional logs.
• Shortcode output uses escaping, sanitization, and scoped classes.
