What port does LLMNR use?

LLMNR uses port UDP 5355 to send the multicast network address. Windows uses LLMNR to identify the server of a file-share.

Why would you use LLMNR?

NetBIOS and LLMNR are protocols used to resolve host names on local networks. Their main function is to resolve host names to facilitate communication between hosts on local networks. LLMNR is designed for consumer-grade networks in which a domain name system (DNS) server might not exist.

What is mDNS discovery?

In computer networking, the multicast DNS (mDNS) protocol resolves hostnames to IP addresses within small networks that do not include a local name server. mDNS can work in conjunction with DNS Service Discovery (DNS-SD), a companion zero-configuration networking technique specified separately in RFC 6763.

What is Windows LLMNR?

The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link. It is included in Windows Vista, Windows Server 2008, Windows 7, Windows 8 and Windows 10.

What is the LLMNR address for UDP port 5355?

LLMNR is defined in RFC 4795 . In responding to queries, responders listen on UDP port 5355 on the following link-scope Multicast address : IPv6 – FF02:0:0:0:0:0:1:3 (this notation can be abbreviated as FF02::1:3), MAC address 33-33-00-01-00-03

Where does the host listen on TCP port 5355?

The responders also listen on TCP port 5355 on the unicast address that the host uses to respond to queries. ID – A 16-bit identifier assigned by the program that generates any kind of query. QR – Query/Response. OPCODE – A 4-bit field that specifies the kind of query in this message.

What do I need to know about ports in Windows?

The most important information is the port number, the local port name and the process ID. With the process ID we can take a look in the Windows Task Manager to try and link it to a process running on the system. To do that you need to start the task manager (press Ctrl Shift Esc).
