Smdn.Net.AddressResolution 1.1.0

Smdn.Net.AddressResolution-1.1.0

A network address resolution library for .NET.

This library provides APIs for resolving between IP addresses and MAC addresses, mainly the MacAddressResolver class in the Smdn.Net.AddressResolution namespace.

This library also provides a functionality for referencing the system's address table such as the ARP table (Smdn.Net.AddressTables namespace), and a network scan functionality to refresh the address cache mainly using the installed commands (Smdn.Net.NetworkScanning namespace).
