In UDP client communication, the W5500 supports up to 8 independent and simultaneously usable sockets, similar to TCP. This means you can have up to 8 UDP connections at the same time. For examples of TCP/IP client-server communication and memory allocation, you can refer to the technical documentation available on the WIZnet website. Specifically, you can find detailed examples and guides on setting up TCP/IP client-server communication and managing socket memory in the following resources: - [W5500 TCP Application](https://docs.wiznet.io/Product/iEthernet/W5500/Application/tcp) - [W5100S TCP Application Note](https://docs.wiznet.io/Product/iEthernet/W5100S/Application-Note/tcp) These resources provide step-by-step instructions and code examples to help you implement TCP/IP client-server communication and manage memory allocation effectively. If you need further assistance, feel free to ask! WIZnet AI Support Team
