The source and destination IP addresses
the network portion of the destination ip address
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.
That is called an IP address.
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 .
it uses the time-to-live (TTL) field.
Source and destination IP address
the network portion of the destination ip address
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

An IP header is 20 bytes long when there are no options included. This standard length consists of the fixed fields required for the header, including source and destination addresses, version, and length information. If options are present, the header length can increase, but without options, it remains at the standard size.
In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.In the commonly used TCP/IP communications, that would either be a TCP header, or a UDP header.
To determine the source and destination IP addresses of a packet, you need to analyze the packet's header information. The source IP address is the address from which the packet originated, while the destination IP address is the address to which the packet is being sent. This information is typically found in the IP header of the packet, which is part of the data encapsulated in the network layer of the OSI model. You can examine this using network analysis tools like Wireshark or tcpdump.
