While convenient, it can also mask shadow IT, increase takeover risks, or hide malicious activity. The **Subdomains** view in Total View gives you complete visibility into every discovered subdomain — including wildcards — at massive scale. ![Overview of paypal.com domain metrics and subdomain details in a web analysis tool.](https://cdn.document360.io/8e5460b3-9d96-4b01-8bb3-6591a4af3a8c/Images/Documentation/Screenshot 2026-06-24 at 12.46.18 PM.png) ## Why Subdomains Matter - Subdomains dramatically expand the attack surface - Attackers register lookalikes, abuse wildcards, or hijack forgotten subdomains - Large enterprise domains like **paypal.com** can have thousands of active subdomains - Sudden spikes in new subdomains often signal reconnaissance or compromise ## Key Features in the Updated View - **Domain Wide View** toggle – expands discovery across the entire domain hierarchy - Clear display of total subdomain count and associated A records - **Basic Raw Data** button for unfiltered details, including TTLs and raw resolutions - Sortable table with **First Seen** and **Last Seen** timestamps - Color-coded indicators and hover tooltips for quick context - Bulk actions: Select All, Download CSV, Monitor, Save To ## How It Works Silent Push continuously aggregates subdomain data from global passive DNS sources. The view is tightly integrated with PADNS, allowing one-click pivots from any subdomain to its full resolution history. Wildcards are automatically flagged, and **Domain Wide View** helps reveal hidden or dynamically resolved subdomains that would otherwise stay invisible. ## How to Use Subdomains View 1. Search a domain (e.g. `paypal.com`) in Total View 2. Click the **Subdomains** tab (shows count like **1795**) 3. Toggle **Domain Wide View** to include full hierarchy 4. Use filters, **Basic Raw Data**, or **Clear Filters** as needed 5. Click any subdomain to pivot to PADNS, Infrastructure Variance, or Threat Feeds ## Real-World Example: paypal.com The updated interface shows **1,795 subdomains**. Examples include long hashed subdomains such as: `0cd20b6fe61233e4a24bf70f30c9ba46.paypal.com` Each entry displays precise **First Seen** and **Last Seen** dates, making it easy to track infrastructure changes and detect anomalies. ## Use Cases - Detect shadow IT and forgotten assets at scale - Identify wildcard abuse and potential subdomain takeovers - Correlate subdomains with PADNS data to trace resolutions to suspicious IPs - Support compliance audits and attack surface management - Set up real-time **Monitor** alerts for new or changed subdomains **Available in both Community and Enterprise editions.** The refreshed Subdomains view turns a traditionally hard-to-manage problem into a clear, actionable intelligence layer — essential for modern threat hunting and attack surface reduction.
