What is a TCP port used for?

TCP is one of the two main ways to transmit data in a TCP/IP network. UDP, which is a best-effort connectionless protocol, is the other one. For devices to communicate via TCP, they use TCP ports. Generally, a TCP port represents an application or service-specific endpoint identifier.

What port is DHCP?

DHCP is a network protocol to used to configure IP networks. A DHCP server listens to UDP port 67 and dynamically assigns IP addresses and other network parameters to DHCP clients. These clients will listen for responses on UDP port 68.

What port is 443 used for?

Port 443 is a virtual port that computers use to divert network traffic. Billions of people across the globe use it every single day. Any web search you make, your computer connects with a server that hosts that information and fetches it for you. This connection is made via a port – either HTTPS or HTTP port.

Is port 443 TCP or UDP?

There are services running on this web server that are using well known port numbers. UDP port 53 is used for DNS, TCP port 80 is used for non-encrypted web services, and TCP port 443 is used for encrypted web services.

Is port 80 and 8080 the same?

No Port 80 and Port 8080 are not the same. Ports are used to make connections unique and range from 0 to 65535 out of which upto 1024 are called well known ports which are reserved by convention to identify specific service types on a host. 80 is reserved for HTTP.

Why does DHCP use 2 ports?

The reason TWO reserved ports are used, is to avoid ‘waking up’ and scheduling the BOOTP server daemons, when a bootreply must be broadcast to a client. Since the server and other hosts won’t be listening on the ‘BOOTP client’ port, any such incoming broadcasts will be filtered out at the kernel level.

What is TCP 464 used for?

Side note: UDP port 464 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 464 makes possible the transmission of a datagram message from one computer to an application running in another computer.

Why is port 139 open?

If you are on Windows-based network that is running NetBios, it is perfectly normal to have port 139 open in order to facilitate that protocol. If you are not on a network using NetBios, there is no reason to have that port open.

Should I open port 445?

We also recommend blocking port 445 on internal firewalls to segment your network – this will prevent internal spreading of the ransomware.
