Layer 3 of the OSI model. An ICMP header follows the IP header of the IP packet.
the Layer 2 source and destination address
Network Layer
The Network layer (Layer 3, typically IP) will receive a segment from the Transport layer (Layer 4, typically TCP or UDP), and will add its own header to it to create a packet. The size of the packet will thus always be the size of the segment plus the Network layer header, the same as when the next layer down (the Data Link layer, layer 2, typically Ethernet) encapsulates the packet into a frame for transmission.
UDP is a Transport layer protocol or fourth layer protocol. UDP is a connection less protocol used in transport layer. UDP header have four fields in total .

destination host address
The destination host address
The data link layer header contains the destination and source of information of the original frame and device sending information. You will also find that it contains the information of the device to receive it.
