TCP port 53 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection. Attention! Commonly Hacked Ports - dummies TCP and UDP port 53 — DNS (Domain Name System) TCP port 443 — HTTP (Hypertext Transport Protocol) and HTTPS (HTTP over SSL) TCP port 110 — POP3 (Post Office Protocol version 3) TCP and UDP port 135 — Windows RPC. TCP and UDP ports 137–139 — Windows NetBIOS over TCP/IP. Transmission Control Protocol - Wikipedia The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite.It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP.TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts
The port 53 waits for requests from DHCP to transfer the data over the network. It operates on the Application Layer of the TCP/IP Model. TCP protocol is used by the Zone Transfer function of the DNS server. Once the connection is established, the zone data will be sent by the server using the TCP 53 port.

How to prevent users from circumventing OpenDNS using
The DNS uses TCP Port 53 for zone transfers, for maintaining coherence between the DNS database and the server. The UDP protocol is used when a client sends a query to the DNS server. The TCP protocol should not be used for queries as it gives a lot of information, which is useful to attackers. Apex Legends - Opening ports for connection issues Ports are endpoints between two connections. A port number is assigned to each end, like an address, to direct the flow of internet traffic. If you’re having trouble connecting to any of our online games — and you have tried basic connection troubleshooting — you may need to open some ports on your network connection.. Consoles
