IP (internet Protocol) is considered more reliable than UDP (User Datagram Protocol) because it is responsible for delivering packets across networks using error-checking and routing mechanisms. However, it's important to note that IP itself does not guarantee delivery, order, or error correction; it only manages addressing and forwarding. UDP, on the other hand, is a connectionless protocol that does not provide reliability features such as retransmission of lost packets or acknowledgment of receipt, making it less reliable than IP. In summary, while neither is fully reliable, IP has more mechanisms in place to enhance data delivery compared to UDP.
When IP sends a packet, it receives a confirmation for each packet and, if needed, rebroadcast the packet. This makes it reliable. UDP does not get confirmation. It broadcast each packet only once and assumes that it get to you. This makes it less reliable then IP because it does not check for problems or rebroadcast.
1. IP works at network layer, UDP works at transport layer. 2. UDP carries application data, IP carries TCP segments or UDP datagrams.

Did you try Wireshark?
Transport layer TCP/IP Protocols are TCP and UDP

An important difference is that TCP includes mechanisms for reliable data communication (lost parts of the communication are re-sent), UDP doesn't. TCP is used when such a reliable communication is important. When speed is more important than reliability, UDP is used instead. This is the case with phone or video communication over the Internet.An important difference is that TCP includes mechanisms for reliable data communication (lost parts of the communication are re-sent), UDP doesn't.

Because TCP does far more things than UDP. UDP does not do flow control or congestion control or guarantee in-order and reliable packet delivery. TCP does all those things therefore it needs more functionality.

Just as much as Ethernet or Arcnet does: you simply cannot use TCP/IP (and UDP/IP), without revealing your IP address.
