I'll create a web app that can read IP addresses from Excel uploads and display their information in a table format.

I've created a comprehensive IP address analyzer web app with the following features:

Key Features:

1. Excel File Upload: Upload .xlsx or .xls files containing IP addresses in the first column
2. Manual IP Entry: Enter IP addresses manually, one per line

3. Comprehensive IP Information:

   • Hostname (via reverse DNS lookup)
   • Geographic location (city, region, country)
   • Organization/ISP information
4. Results Table: Clean, organized display of all IP information
5. Export Functionality: Export results to CSV format
6. Error Handling: Shows status for each IP lookup with error messages

How it works:

• File Processing: Uses the xlsx library to parse Excel files
• IP Validation: Validates IPv4 and IPv6 addresses
• DNS Lookup: Performs reverse DNS lookups to get hostnames
• Geolocation: Uses the ip-api.com service for location and organization data
• Server Actions: Processes everything server-side for security and performance

The app provides a professional interface with tabs for different input methods, loading states, and comprehensive error handling. Users can easily upload their IP lists and get detailed information displayed in an organized table format.

I'll add a dedicated page to display the list of IPs with their names in a clean table format, and update the navigation to include this new page.

I've added a comprehensive IP Directory page with the following features:

New Features:

IP Directory Page (/ip-list)

• Complete IP List: Shows all analyzed IP addresses with their names/hostnames
• Advanced Filtering: Search by IP, hostname, city, country, or organization
• Status & Country Filters: Filter by lookup status or specific countries
• Statistics Dashboard: Shows total IPs, success/failure rates, and unique countries

Enhanced Navigation

• Navigation Bar: Clean navigation between IP Analyzer and IP Directory
• Active State: Shows current page with visual indicators

Key Features of the IP List Page:

1. Statistics Cards:

   • Total IP count
   • Successful vs failed lookups
   • IPs with hostnames
   • Number of unique countries

2. Advanced Search & Filtering:

   • Real-time search across all fields
   • Filter by lookup status (success/error)
   • Filter by country
   • Export filtered results to CSV

3. Detailed Table View:

   • IP addresses with hostnames prominently displayed
   • Location information with country badges
   • Organization details
   • Individual refresh buttons for each IP
   • Status indicators with error messages

4. Data Management:

   • Refresh individual IP information
   • Bulk export functionality
   • Persistent storage of analyzed IPs

The page provides a professional directory view where users can easily browse, search, and manage their IP address database with detailed information including hostnames (names) for each IP address.
