A tool to list IP addresses in a network while optionally pinging and performing DNS lookups. This can be useful when you need a comma or newline delimited list of IP addresses in a network or if you just want to see which hosts are up on a given subnet. The port scanner allows you to quickly view open TCP services on a host. IPList is written in C# using Visual Studio 2019 and Xamarin as an introduction to macOS development with C#.

• List all IP address in a network
• Ping scan of a network to determine host availability
  • DNS lookup
  • ARP lookup
• Extra Tools
  • Whois lookup
• Port scan of any network host to determine service availability
• Read data from open ports:
  • SMTP "ehlo"
  • HTTP/S with headers
  • CIFS share listing
  • Raw data when protocol is unknown
• Constant ping against a network host to monitor availability
• Copy results to the clipboard with a user defined delimiter
• User definable timeouts and port scanning list (top 1000 and 100 ports, all ports, custom list)
• Check for updates from the main menu or on program startup
• Multithreaded for performance

IPList relies on the awesome IPNetwork and SharpCifs.Std libraries and runs on macOS 10.10 or higher. A binary is available here otherwise it can be easily compiled with Visual Studio 2019.

In no particular order, here are some of the resources I used to hack this project together:

• IPNetwork
• SharpCifs.Std
• Windows in Xamarin.Mac
• Images in Xamarin.Mac
• Menus in Xamarin.Mac
• Table Views in Xamarin.Mac
• ThreadPool Class
• Thread Class
• Using TCP Services
