UDP is used by applications that do not require the level of service of TCP or that wish to use communications services (e.g., multicast or broadcast delivery) not available from TCP. UDP is almost a null protocol; the only services it provides over IP are checksumming of …
Online IPv6 Port Scanner | IPv6 Firewall Tester Welcome to IPscan, the open source IPv6 port scanner, or firewall tester, which checks multiple, user-selectable TCP, UDP and ICMPv6 services. IPscan offers much of the functionality you might hope to find in an IPv6 version of GRC's ShieldsUP® utility. So far over 105158 IPv6 hosts, and of the order of 7781650 IPv6 ports, have been tested. Cisco Self-Study: Implementing Cisco IPv6 Networks (IPV6 User Datagram Protocol (UDP) and IPv6. UDP (protocol 17) is considered an upper-layer protocol by IPv4 and IPv6. UDP has not been changed for IPv6 and continues to run on top of both IPv6 and IPv4 headers. However, as shown in Figure 2-7, the Checksum field in the UDP packet is mandatory with IPv6. This field was optional in IPv4. IPV6 Scanner | Online Port Scan
2.1. IPv6 Daytime server (TCP/UDP) The TCP and UDP versions of the daytime server program use a common function to create the server socket, the listen_server function. This function generates a server socket from a hostname, the service, socket family (IPv4 or IPv6) and socket type (TCP or UDP) parameters. 2.1.1. File "listen_server.h"
The message event is fired, when a UDP packet arrives destined for this server. The listening event is fired, when the server has initialized and all ready to receive UDP packets. dgram.createSocket() can either accept 'udp4' or 'udp6'. The former uses IPv4, the later uses IPv6.

Send a UDP/IPv6 message. If the return value is OT_ERROR_NONE, OpenThread takes ownership of aMessage , and the caller should no longer reference aMessage . If the return value is not OT_ERROR_NONE, the caller retains ownership of aMessage , including freeing aMessage if the message buffer is no longer needed. UDP communication via IPv6. Hi, I've took at look at the implementation of UDP client and it creates the internal socket with the address family you pass to the
