it indicates which layer 4 protocol is carried in a datagram
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.
The "packets" are actually called "segments" in the case of layer 4 (i.e., TCP or UDP).When creating an IP packet, a host (computer, or other equipment that participates in a communication) adds information to the "protocol" field. This indicates whether the IP packet transports a TCP segment, a UDP segment, or some other kind of information.The "packets" are actually called "segments" in the case of layer 4 (i.e., TCP or UDP).When creating an IP packet, a host (computer, or other equipment that participates in a communication) adds information to the "protocol" field.

no, service of UDP
Internet Protocol (IP)
The older protocol for this purpose was BOOTP, but modern addressing LAN schemes today will use DHCP.
The IP protocol creates all IP packets.
IP stands for Internet Protocol and it is is a numerical label that is assigned to devices participating in a computer network that uses the Internet Protocol for communication between its nodes.
IP means Internet Protocol
TCP is a sub-protocol within the IP protocol. Think of TCP as one of the instruments in a band.
TCP-IP is a protocol, not a transmission medium. Bandwidth doesn't affect it.
In IP version 4, an IP address has 32 bits, or 4 bytes.In IP version 4, an IP address has 32 bits, or 4 bytes.In IP version 4, an IP address has 32 bits, or 4 bytes.In IP version 4, an IP address has 32 bits, or 4 bytes.
A DHCP server assigns the computer the IP address, while the DNS servers are responsible for providing names and lookup addresses when a computer requests the IP address of a hostname.
