| 8084 | tcp | websnp | Apache Tomcat server (Netbeans JSP servlets) IBM Lotus Sametime server uses this port. To allow internal users to participate in interactive audio/video meetings with users from the Internet, you must either open TCP port 8084 (the default TCP Tunneling port for the Audio/Video Services) or a range of UDP ports through the internal firewall.

Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.

There are 65,535 possible port numbers. Services listen on well-known port numbers in the range 1–1023. Some of the most used service port numbers are: Port 80: Web (HTTP)
Is port 8000 TCP or UDP? ›
TCP Port 8000 is commonly used for development environments of web server software. It generally should not be exposed directly to the Internet.
How to tell if a port is using TCP or UDP? ›
Use the lsof command, a variant of the netstat -af command to identify TCP sockets that are in the LISTEN state and idle UDP sockets that are waiting for data to arrive.
What is the port 8084 used for? ›
you are correct, TCP/8084 is used for Android devices with EST authentication (ISE Installation Guide). If it is DISABLE, then click on Enable Certificate Authority.
What is the highest usable port number? ›
The highest TCP port number is 65,535. The TCP protocol provides 16 bits for the port number, and this is interpreted as an unsigned integer; all values are valid, apart from 0, and so the largest port number is (2^16 - 1) or 65,535.
What is a reasonable port number? ›
TCP/IP Ports
There are a number of common networking ports that are used frequently. Ports 0 through 1023 are defined as well-known ports. Registered ports are from 1024 to 49151. The remainder of the ports from 49152 to 65535 can be used dynamically by applications.
Does Netflix use TCP or UDP? ›
"Netflix uses TCP because TCP is much time-sensitive and does not require port forwarding. It helps to enable the full bandwidth of the network. We can compress more data at once in TCP and also reloaded data packets do not pose a problem. It also ensures higher video quality and fewer network congestion problems.
What is the best port for TCP? ›
Arguably the single most famous port on the Internet, TCP port 80 is the default that HyperText Transfer Protocol Web servers listen on for Web browser requests. Port 443 is the default for secure HTTP.
What is UDP port 8000 used for? ›
Port 8000 Details. Commonly used as an alternate HTTP port. Some firewalls use it for HTTP web administration. Also commonly used for internet radio streams using Nicecast/Icecast/Shoutcast/Winamp audio streaming.
Does wifi use TCP or UDP? ›
Tcp and udp is a protocol which does not depend on wire or wire less communication. Both can work in wired and wireless network.
UDP is commonly used in time-sensitive communications where occasionally dropping packets is better than waiting. Voice and video traffic are often sent using this protocol because they are both time-sensitive and designed to handle some level of loss.
Does DNS use TCP or UDP? ›
DNS has always been designed to use both UDP and TCP port 53 from the start 1 , with UDP being the default, and fall back to using TCP when it is unable to communicate on UDP, typically when the packet size is too large to push through in a single UDP packet.
Is 8081 TCP or UDP port? ›
Port 8081 Details. Hyper Text Transfer Protocol (HTTP) - alternative ports used for web traffic. See also TCP ports 80, 81, 8080. Dreambox 8000 also uses port 8081 (TCP/UDP).
Is mumble port TCP or UDP? ›
The murmur server uses port 64738 TCP and UDP by default.
