krolawdhcp4可以根据客户端网卡名和客户端地址获取服务器端ipv4和ipv6地址吗请用golang写一个示例

以下是一个示例程序，使用krolaw/dhcp4库获取客户端的IPv4和IPv6地址：

package main

import (
	"fmt"
	"net"

	"github.com/krolaw/dhcp4"
)

func main() {
	// 客户端地址和网卡名
	clientAddr := net.ParseIP("192.168.1.100")
	clientHwAddr, _ := net.ParseMAC("00:11:22:33:44:55")

	// DHCP请求
	requestPacket, err := dhcp4.NewRequestPacket(dhcp4.BootRequest)
	if err != nil {
		fmt.Println("Failed to create DHCP request packet:", err)
		return
	}
	requestPacket.AddOption(dhcp4.OptParameterRequestList,
		[]byte{dhcp4.OptionIPAddressLeaseTime, dhcp4.OptionRouter, dhcp4.OptionDNS, dhcp4.OptionDomainNameServer})
	requestPacket.AddOption(dhcp4.OptDHCPMessage, []byte{byte(dhcp4.DHCPDiscover)})
	requestPacket.AddOption(dhcp4.OptClientIdentifier, clientHwAddr)
	requestPacket.AddOption(dhcp4.OptRequestedIPAddress, clientAddr)

	// 发送DHCP请求并等待响应
	responsePacket, err := dhcp4.SendRequestPacket(requestPacket, "udp4", "255.255.255.255:67", "255.255.255.255:68", 5*time.Second)
	if err != nil {
		fmt.Println("Failed to send DHCP request:", err)
		return
	}

	// 解析响应
	leaseTime, _ := responsePacket.GetOptionValue(dhcp4.OptionIPAddressLeaseTime)
	routerIPs, _ := responsePacket.GetOptionValue(dhcp4.OptionRouter)
	dnsIPs, _ := responsePacket.GetOptionValue(dhcp4.OptionDNS)
	domainNameServers, _ := responsePacket.GetOptionValue(dhcp4.OptionDomainNameServer)

	// 输出IPv4地址和IPv6地址
	fmt.Println("IPv4 address:", clientAddr)
	if len(routerIPs) > 0 {
		fmt.Println("IPv6 address:", net.ParseIP(string(routerIPs)))
	}
}

注意：这个示例程序只能获取IPv6地址，如果服务器没有配置IPv6地址，将无法获取
