TCP protocol is used by the Zone Transfer function of the DNS server. Once the connection is established, the zone data will be sent by the server using the TCP 53 port. However, when the query has to be transferred from the client computer, it will be sent using the port 53 on UDP protocol.
Mar 29, 2020 · An SMB port is a network port commonly used for file sharing. IBM programmer Barry Feigenbaum developed the Server Message Blocks (SMB) protocol in the 1980s for IBM DOS. SMB continues to be the de facto standard network file sharing protocol in use today. Live View video is setup using the Session Initiation Protocol (SIP) with TCP or UDP ports 15063 or 15064. Audiovisual data is transported using UDP to ports negotiated via SIP. These ports can range from 16500 to 65000. The Ring application listens for connections primarily over ports 7076/7077 as well as 9078/9079. Additionally, if Internet Protocol security (IPsec) is deployed in your organization, IPsec must be disabled over the range of ports used for the delivery of audio, video, and panorama video. While this may seem a bit daunting at first, the heavy lifting for planning this can be done using the Skype for Business Server 2015 Planning Tool .

Well-Known TCP/UDP Ports 0 to 1023: Port # Portocol: Description: Status: 0: TCP, UDP: Reserved; do not use (but is a permissible source port value if the sending process does not expect messages in response) Ports are identified for each protocol and address combination by 16-bit unsigned numbers, commonly known as the port number. The most common protocols that use port numbers are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). Nov 02, 2017 · Port numbers 0 to 1024 are reserved for privileged services and designated as well-known ports. This list of port numbers are specified in RFC 1700. In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. By default, the IMAP protocol works on two ports: Port 143 - this is the default IMAP non-encrypted port; Port 993 - this is the port you need to use if you want to connect using IMAP securely; What is SMTP and which are the default SMTP ports. Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending emails across the Internet.
Newcomers to the Windows ecosystem generally confuses port numbers of SMB. SMB service is provided over two ports. TCP port 139 is SMB over NETBIOS. NETBIOS is a transport layer protocol designed to use in Windows operating systems over the network. TCP 445 is SMB over IP. This is a newer version where SMB can be consumed normally over the IP
