net

The net module provides a set of functions for working with network addresses and performing network lookups.

This module does not yet provide a way to create network connections or servers. Feel free to open a GitHub issue if you would like to see this functionality added.

The core functionality is provided by the Go standard library's net (opens in a new tab) package.
