How to perform DNS lookups and resolve domain names to IP addresses in Go?

In Go, you can perform DNS lookups and resolve domain names to IP addresses using the net package. Here's an example code snippet:

package main

import (
	"fmt"
	"net"
)

func main() {
	domain := "example.com"

	// Resolve the domain name to IP addresses
	ipAddresses, err := net.LookupIP(domain)
	if err != nil {
		fmt.Println("DNS lookup failed:", err)
		return
	}

	// Print all the IP addresses associated with the domain
	for _, ipAddress := range ipAddresses {
		fmt.Println(ipAddress)
	}
}

In the example above, we use the LookupIP function from the net package to perform a DNS lookup for the specified domain. It returns a slice of net.IP addresses associated with the domain. We can then iterate over these addresses and print them.

You can run this code by saving it to a file (e.g., dns_lookup.go) and executing go run dns_lookup.go. Replace "example.com" with the domain name you want to resolve.
