Tolong jelaskan mengenai [place holder] dari Protokol Internet

Berikut ini adalah contoh dari datagram IP (packet capture dari Microsoft Network Monitor, dipantau dengan perintah "Ping 192.168.1.2"):

+  Frame: Base frame properties

+  ETHERNET: ETYPE = 0x0800: Protocol = IP:  DOD Internet Protocol

IP:   ID = 0x34CD; Proto = ICMP; Len: 60

IP:   Version = 4 (0x4)

IP:   Header Length = 20 (0x14)

IP:   Type of Service = Normal Service

IP:   Total Length = 60 (0x3C)

IP:   Identification = 13517 (0x34cd)

IP:   Flags Summary = 0 (0x0)

IP: .......0 = Last fragment in datagram

IP: ......0. = May fragment datagram if necessary

IP:   Fragment Offset = 0 (0x0) bytes

IP:   Time to Live = 128 (0x80)

IP:   Protocol = ICMP - Internet Control Message

IP:   Source Address = 192.168.1.1

IP:   Destination Address = 192.168.1.2

IP:   Data: Number of data bytes remaining = 40 (0x0028)

+  ICMP: Echo: From 192.168.1.1 To 192.168.1.2

Terdiri dari 4 lapisan yaitu:
