The answer is DNS is mostly UDP Port 53, but as time progresses, DNS will rely on TCP Port 53 more heavily. 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.

Difference between TCP 1433 and UDP port 1434 2013-10-18 · The default instance would listen on TCP port 1433, while the other named instances could listen on TCP ports 1434 and 1954, respectively. The network administrator would then configure the firewall to forward network requests for UDP port 1434 and TCP ports 1433, 1434, and 1954 on that IP address.-----Thanks,Suhas Vallala * TCP and UDP (Generic) - Nagios Exchange Simple TCP Port ant Ping Check in PowerShell This Script Will Test if TCP Port Connection is open and if it pings --EXAMPLE .check_testport.ps1 -Server SERVER-ADDRESS OK : PingReplyDetails: 32ms --EXAMPLE 1 .check_testport.ps1 -Server SERVER-ADDRESS FAIL: Ping Timeout -- EXAMPLE 2 .che

2016-6-9 · UDP port forwarding is a bit more complicated. We will need to convert the packets from UDP to TCP on the SSH client side, tunnel it over the SSH connection and convert it back from TCP to UDP on the SSH server side. We will tunnel UDP port 53 on server02 to UDP port 53000 on the client. We will use TCP port 8000 for the SSH tunnel.

Attention! TCP guarantees delivery of data packets in the same order in which they were sent. Guaranteed communication over TCP port is the main difference between TCP and UDP. UDP port would not have guaranteed communication as TCP.
