Question

What is the largest possible source port number? (Hint:see the hint in 4.)

The image displays a packet analysis of an Internet Protocol Version 4 (IPv4) datagram using a network tool, likely Wireshark. Below is the detailed transcription and explanation of the fields shown in the image: ### Internet Protocol Version 4 - **Source IP Address:** 10.0.0.2 - **Destination IP Address:** 239.255.255.250 - **Version:** 4 - **Header Length:** 20 bytes - **Differentiated Services Field:** 0x00 (DSCP: CS0, ECN: Not-ECT) - **Total Length:** 63 bytes - **Identification:** 0x17f0 (6128) - **Flags:** 0x40, Don't fragment - **Fragment Offset:** 0 - **Time to Live (TTL):** 64 - **Protocol:** UDP (17) - **Header Checksum:** 0x28c2 (validation disabled) - **Header Checksum Status:** Unverified ### User Datagram Protocol (UDP) - **Source Port:** 32907 - **Destination Port:** 15600 - **Length:** 43 bytes - **Checksum:** 0xffe8 (unverified) - **Checksum Status:** Unverified - **UDP Payload Size:** 35 bytes ### Data - The data section mentions a payload of 35 bytes, but the exact data content is not displayed. This breakdown shows an IPv4 datagram carrying a UDP packet without any fragmentation. The total length of the datagram is 63 bytes, including the headers and the payload. The destination address is a multicast address, often used for network services like UPnP (Universal Plug and Play). The unverified checksum fields indicate that the packet's integrity validation is not performed in this capture.
