How do I find the UDP header port number?
Source Port is 2 Byte long field used to identify the port number of the source. The source port number is the first four hexadecimal digits i.e. 06 32 if we convert hexadecimal to decimal we get 1586.
What is a UDP header?
UDP header is an 8-bytes fixed and simple header, while for TCP it may vary from 20 bytes to 60 bytes. The first 8 Bytes contains all necessary header information and the remaining part consist of data. Checksum: Checksum is 2 Bytes long field.
Which application uses UDP port?
Numerous key Internet applications use UDP, including: the Domain Name System (DNS), where queries must be fast and only consist of a single request followed by a single reply packet, the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP) …
What is the largest possible source port number for UDP?

Which are the two types of port numbers are there in UDP?
Port numbers above 1023 can be either registered or dynamic (also called private or non-reserved). Registered ports are in the range 1024 to 49151. Dynamic ports are in the range 49152 to 65535.
What is a port number in UDP?
User Datagram Protocol (UDP) is a Transport Layer protocol. UDP is a part of Internet Protocol suite, referred as UDP/IP suite. UDP port number fields are each 16 bits long, therefore range for port numbers defined from 0 to 65535; port number 0 is reserved. Port numbers help to distinguish different user requests or process.
What are the applications of UDP protocol?
Applications of UDP: 1 Used for simple request response communication when size of data is less and hence there is lesser concern about flow and error control. 2 It is suitable protocol for multicasting as UDP supports packet switching. 3 UDP is used for some routing update protocols like RIP (Routing Information Protocol).
