Created Using Ivy

Web application created using Ivy-Framework.

Ivy - The ultimate framework for building internal tools with LLM code generation by unifying front-end and back-end into a single C# codebase. With Ivy, you can build robust internal tools and dashboards using C# and AI assistance based on your existing database.

Ivy is a web framework for building interactive web applications using C# and .NET.

Interactive Example For DNS Lookups

This example demonstrates DNS query operations using the DnsClient.NET library integrated with Ivy. DnsClient.NET is a simple yet very powerful and high performant open source library for the .NET Framework to do DNS lookups.

What This Application Does:

This specific implementation creates a DNS Lookup Tool that allows users to:

• Query DNS Records: Perform DNS lookups for multiple record types (A, AAAA, MX, TXT, CNAME, NS, PTR, SRV, SOA)
• Detailed Information Display: Shows IP addresses, mail servers with priorities, text records, name servers, and more
• Query Status Tracking: View query success status, name server, record count, and message size
• Record Sections: Organized display of Answers and Authority sections
• Domain Validation: RFC 1035/1123 compliant domain name validation
• Interactive UI: Clean card-based layout with structured data presentation

Technical Implementation:

• Uses DnsClient.NET's LookupClient with singleton pattern for optimal performance
• Type-specific rendering for each DNS record type (A, AAAA, MX, TXT, CNAME, NS, PTR, SRV, SOA)
• Displays detailed record data: IPv4/IPv6 addresses, mail server priorities, TTL values
• Implements async DNS queries with error handling and toast notifications
• Domain validation using regex patterns (RFC 1035/1123 compliant)
• Signal-based component communication for reactive UI updates
• Split display with query form and detailed results sections

How to Run

1. Prerequisites: .NET 9.0 SDK
2. Navigate to the example:

   cd dnsclient

3. Restore dependencies:

   dotnet restore

4. Run the application:

   dotnet watch

5. Open your browser to the URL shown in the terminal (typically http://localhost:5010)

How to Deploy

Deploy this example to Ivy's hosting platform:

1. Navigate to the example:

   cd dnsclient

2. Deploy to Ivy hosting:

   ivy deploy

This will deploy your DNS lookup application with a single command.
