How to create static ARP cache entries programatically in Windows XP

Question

Is there are way to set ARP cache entry in C#?

The only way I have found is related to use of arp utility Address Resolution Protocol

Static entries added with the arp -s command are not expired from the cache.

There are related post about How do I access ARP-protocol information through .NET?

Answer 1

It wouldn't be purely .NET obviously, but you should be able to do it via the Win32 API in the IP Helper API library - namely the CreateIpNetEntry and SetIpNetEntry methods. You would likely want to do this via P/Invoke or a wrapped managed C++ library.
