What is UDP 17500 used for?
Dropbox LanSync Protocol (db-lsp) also uses port 17500 (TCP/UDP). It is used to synchronize file catalogs between Dropbox clients on a local network.
Is UDP port 0 valid?
Unlike most port numbers, port 0 is a reserved port in TCP/IP networking, meaning that it should not be used in TCP or UDP messages. The Internet Assigned Numbers Authority (IANA) maintains an official listing of the intended usage of these port numbers on the internet, and system port 0 is not to be used.
Does UDP use port443?
Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 443, UDP Port 443 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 443 to process any errors and verify correct delivery.
What is Dropbox LAN sync?
What is LAN sync? A LAN, local area network, is a wireless or Ethernet connection between computers and other devices in a specific location. Enabling LAN sync tells Dropbox to use your LAN to sync files that are stored on your LAN, which may speed up syncing for those files.
What port is UDP on?
The most common UDP packets—DNS registrations and name-resolution queries—are sent to port 53. In contrast, TCP ports support only connection-oriented protocols. A connection-oriented protocol requires that network endpoints establish a channel between them before they transmit messages.
Should I block port 0?
Best Answer. Port 0 generally refers to malformed or malicious traffic. You could always block it coming from outside traffic, so anything that does not have your internal IP addressing scheme.

Is the UDP protocol a connectionless protocol?
User Datagram Protocol (UDP) is a simple protocol that makes a best effort to deliver data to a remote host. However, because the UDP protocol is a connectionless protocol, UDP datagrams sent to the remote endpoint are not guaranteed to arrive, nor are they guaranteed to arrive in the same sequence in which they are sent.
Which is the port to listen for UDP datagrams?
The following code example uses a UdpClient to listen for UDP datagrams on port 11,000. The client receives a message string and writes the message to the console. The following code example uses a Socket to send UDP datagrams to the directed broadcast address 192.168.1.255, using port 11,000.
How does UDP class communicate with network services?
The UdpClient class communicates with network services using UDP. The properties and methods of the UdpClient class abstract the details of creating a Socket for requesting and receiving data using UDP. User Datagram Protocol (UDP) is a simple protocol that makes a best effort to deliver data to a remote host.
