Question

我正在使用Sharp Pcap捕获数据包，我可以轻松检查IP包或IP数据包的IP：

Dim ip1 As IpPacket = IpPacket.GetEncapsulated(pack)
Dim arp As ARPPacket = ARPPacket.GetEncapsulated(pack)

    If (Not ip1 Is Nothing) Then
        log1.WriteLine("Received IP packet from {0}", ip1.SourceAddress.ToString)
    End If

    If (Not arp Is Nothing) Then
        log1.WriteLine("Received ARP packet from {0}", arp.SenderProtocolAddress.ToString)
    End If

我想找到ICMPPacket的属性，没有运气。如何查看ICMPPacket的源/目标地址？

Answer 1

ICMP数据包是IP数据包的一部分，因此要获取ICMPPacket的源IP，您必须获取IP数据包的源地址，然后检查它是否是ICMPPacket

ICMP数据包的源IP和目的IP
