What port is 5353 used for?
Service Name and Transport Protocol Port Number Registry
| Service Name | Port Number | Transport Protocol |

| dns-llq | 5352 | tcp |
| dns-llq | 5352 | udp |
| mdns | 5353 | tcp |
| mdns | 5353 | udp |
What TCP port is DNS?
port 53
DNS uses port 53.
Can DNS run on TCP?
DNS and some other services work on both the protocols. DNS uses TCP for Zone transfer and UDP for name, and queries either regular (primary) or reverse. UDP can be used to exchange small information whereas TCP must be used to exchange information larger than 512 bytes.
What is Avahi service?
Avahi is a system which enables programs to publish and discover services and hosts running on a local network. For example, a user can plug a computer into a network and have Avahi automatically advertise the network services running on its machine, facilitating user access to those services.
Why DNS uses UDP instead of TCP?
Here is why DNS uses UDP. UDP is much faster when compared to TCP. TCP is slow as it uses 3-way handshake. DNS requests are generally very small and they fit well within UDP segments. UDP is not reliable, but reliability can be added to the application layer.
Is DNS 53 TCP or UDP?
The answer is DNS is mostly UDP Port 53, but as time progresses, DNS will rely on TCP Port 53 more heavily.
Is DNS 53 UDP or TCP?
Is it possible to use multicast DNS over port 5353?
Also, no updates are needed for understanding formats of new packets since DNS packets could already be displayed and decoded by the exiting tools of network packet capture. Over port 5353, the UDP queries could be used for contacting with the mDNS service. Multicast DNS uses suffix of .local, like http://abc.local.
What is TCP port 5353 used for?
About TCP/UDP ports TCP port 5353 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. UDP on port 5353 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice.
What are the services that run on a 5353 server?
There are Services that run on your Servers (i.e. DNSCache DNS Client, CryptSvc, LANManWorkstation, NLASvc Network Location Awareness and WinRM) that broadcast using UDP 5353 to catalog/cache which servers are on the segment. Bonjour is another service that could be present using 5353 (Multicast DNS).
What is userudp on port 5353?
UDP on port 5353 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level. UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768).
