internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet.
ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead

What does the protocol field in the IP header identify?
The protocol field, in the IP header, identifies what kind of data is in the IP packet - the upper-layer protocol. For example, if the code is 6, that means that the data is a TCP segment.
If the Protocol field in the IP header has a decimal value of 17 it means that the higher level protocol using the services of IP is TCP?
no, service of UDP
What type of header does an ARP frame contain?
ARP and RARP protocols are present at network layer. ARP is short form of address resolution protocol. IP is the type of header an ARP frame contain .
What is Internet Protocol (IP)?
Internet Protocol (IP)
What is tcpip header and trailer?
An Ethernet frame has a 14 byte header, a data section, and a 4 byte trailer 14 byte header consist of destination address, source address and type The trailer is for CRC (Cyclic redundancy Check) An Ethernet frame can contain an IP and TCP PDU. IP header most important parts consists of (Version,IHL, Total length,Protocol, source and destination address) In details (Version,Header length,Differentiated services field, total Length, Identification, Flags, fragment offset, Time to live, protocol, header checksum, source and destination address). TCP header most important parts consists of (Source port, Destination port and header Length) In details (Source Port, Destination Port, Sequence number, Acknowledgment number, Header length,Flags,Window and check sum). The details of the IP and TCP header have been taken from a Network protocol Analyzer Wireshark on my own pc.
How many bits does the DSCP use in the IP header?
how many bit header Ip v4
What transport layer protocol does ping use?
Assuming IPv4 ICMP. Ping uses IP for transport. Ping in itself is an "Echo Request", which is a function of the ICMP protocol. The IP Packet will carry the ICMP protocol from end-to-end. ICMP has a protocol number of 1, so the "Protocol" field in the IPv4 header will contain "1" as a reference to the ICMP payload. For IPv6, ICMPv6 is used, and the transport will be IPv6.
Which protocol creates the final IP packet?
The IP protocol creates all IP packets.

Looking at IPSec-encrypted traffic with a sniffer What packet types do you see?
You can see the packages to pass, but you can not see its contents IPSec Packet Types IPSec packet types include the authentication header (AH) for data integrity and the encapsulating security payload (ESP) for data confidentiality and integrity. The authentication header (AH) protocol creates an envelope that provides integrity, data origin identification and protection against replay attacks. It authenticates every packet as a defense against session-stealing attacks. Although the IP header itself is outside the AH header, AH also provides limited verification of it by not allowing changes to the IP header after packet creation (note that this usually precludes the use of AH in NAT environments, which modify packet headers at the point of NAT). AH packets use IP protocol 51. The encapsulating security payload (ESP) protocol provides the features of AH (except for IP header authentication), plus encryption. It can also be used in a null encryption mode that provides the AH protection against replay attacks and other such attacks, without encryption or IP header authentication. This can allow for achieving some of the benefits of IPSec in a NAT environment that would not ordinarily work well with IPSec. ESP packets use IP protocol 50.
