As already stated, an address is the combination of an IP address and a port number. When a socket is created it assumes the IP address of the network node that created it. If a socket has an IP address but not a port number it is said to be ‘unbound’.

UDP IP Address¶ We will now begin to put the pieces together. In this task, we will integrate the logging, DNS and UDP profiles we created earlier with an IP address. The IP address configured on the BIG-IP DNS will listen for queries and process them in accordance with the associated profiles. UDP is commonly used with two types of applications: applications that are tolerant of the lost data – VoIP (Voice over IP) uses UDP because if a voice packet is lost, by the time the packet would be retransmitted, too much delay would have occurred, and the voice would be unintelligible. When possible, administrators use the ip helper-address command to relay broadcast requests for these key User Datagram Protocol (UDP) services. By using the ip helper-address command, a router can be configured to accept a broadcast request for a UDP service and then forward it as a unicast to a specific IP address, as shown in Figure 2-21. The IP stack can only send a UDP message to a remove IP address if it knowns the MAC address associated with the IP address, or the MAC address of the router used to contact the remote IP address. When a UDP message is received from a remote IP address the MAC address and IP address are added to the ARP cache. For multicast, it is a multicast group address. Neither of these addresses are IP address, as they don't go to a particular machine. Broadcast messages go to all machines. Multicast messages goes to all machines who are receiving on that address. Regardless of using unicast, multicast, or broadcast, you are required to provide an address and port. UDP Port Scanner. With this online UDP port scanner you can scan an IP address for open UDP ports. Use this UDP port scan tool to check what services (dns, tftp, ntp, snmp, mdns, upnp) are running on your server, test if your firewall is working correctly, view open UDP ports. An IP address is a 32-bit number assigned to each host on a network. Each device that wants to communicate with other devices on a TCP/IP network needs to have an IP address configured. For example, in order to access the Internet, your computer will need to have an IP address assigned (usually obtained by your router from your ISP).
