Get Local Network Adapter Addresses

See more Socket/SSL/TLS Examples

Demonstrates Socket.GetAdaptersAddresses, which populates a JsonObject with information about local network adapters, including IPv4 addresses, IPv6 addresses, and MAC addresses.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.

Background. This provides a portable way to enumerate the host's network interfaces and their addresses.
