The net package in Go equips developers with powerful tools for networking, including features for DNS address lookup and reverse DNS resolution. By utilizing functions such as `lookup IP`, `lookup addr`, and `lookup cname`, programmers can create versatile applications for querying DNS records, making it easy to retrieve IP addresses or canonical names associated with various domains. An example project demonstrates how to build a simple command-line DNS lookup tool that allows users to input a domain name and retrieve its corresponding IP addresses efficiently. This functionality not only enhances networking capabilities but also supports the creation of advanced tools for managing and resolving network queries in Go.
