MF: 1 bit, this field is required when the datagram is fragmented saying whether the datagram contains some more fragments. Identification: 16 bits, this field is used to identify the fragments of a datagram which will be helpful while reassembling the datagrams as encapsulator might fragment the datagram. Ange IP-nummer: Sökningen är helt anonym, vi sparar inga uppgifter om vem som sökt eller vilket IP-nummer som spårats. Source Quench (Type 4) No icmp error message should be sent to original sender Redirect (Type 5) No icmp error message should be sent to original sender Time Exceeded (Type 6) icmp error message with Type 3 Code 1 should be sent to original sender. Most cases the protocol will be IPv4 unless there is some additional headers for encapsulated packet. Source Route Failed (Code 5) No icmp error message should be sent to original sender. The decapsulator will reassemble the packet. Destination IP Address: 32 bits, this field is the IP address of the decapsulator. To encapsulate an IP packet in another tränade tjejer IP packet, an outer header is added with SourceIP, the entry point of the tunnel and the Destination point, the exit point of the tunnel. IP -adresser går att spåra till ett visst område om man. In is an tunneling that encapsulates one packet in another packet.
