Port 53

The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports Port 53 is a true harbor of local food, boutique wines, top shelf spirits and craft beers. Chef owner Adam Mitchell, with help from his dedicated team, have worked hard to create a restaurant that appeals to everyone with a fantastic range of food and beverages and positioned in a great location Working with Port53 to improve our security posture and efficiency at TigerConnect has been a great experience. From organizing demos to suggesting products that might be of interest, they aided us in many ways to achieve our project goals

Port 53

An open port means that the port is externally visible to clients in the network (or out on the internet, possibly). Contrary to popular belief a server or host does not need to have port 53 open to make outgoing DNS queries - this is not how the TCP/IP model works. You can run tcpdump on a host and then issue a DNS lookup from another. 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 add chain=input action=drop protocol=tcp dst-port=53 comment=Input Drop DNS - Other add chain=input action=drop protocol=udp dst-port=53 comment= The above rule will allow dns requests from the private LAN with the 192.168.1./27 subnet, on the ether5 interface, and drop any other requests The port forwarding tester is a utility used to identify your external IP address and detect open ports on your connection. This tool is useful for finding out if your port forwarding is setup correctly or if your server applications are being blocked by a firewall DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS, larger UDP packets are used

As we witnessed with the dhcpserver port on Felix, certain open UDP services can hide even from Nmap version detection. He has also only scanned the default ports so far, there are 64529 others that could possibly be open. For the record, 53 is the only open UDP port on Scanme TCP port 53 is used for domain transfers; the only reason I can see it being open is if the OP is running a DNS server. DNS servers also listen on UDP port 53 to accept queries from client resolvers.
