Looking for information on Protocol TCP 6666? This page will attempt to provide you with as much port information as possible on TCP Port 6666.
TCP Port 6666 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

Side note: TCP port 6666 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 6666 in the same order in which they were sent. Guaranteed communication over port 6666 is the key difference between TCP and UDP. UDP port 6666 would not have guaranteed communication in the same way as TCP.
Because protocol TCP port 6666 was flagged as a virus (colored red) does not mean that a virus is using port 6666, but that a Trojan or Virus has used this port in the past to communicate.

Port 6666/tcp not UDP has the reputation of BEWARE! due to a few factors. 1. When folks think of the numbers 666 or more, (e.g. four 6’s and up) they think of “evil”. Yes, because of the stereotyping of these numbers, hacks have fed into this fear by the use of trojans AND worms on 666 or in this case port 6666/tcp in the past. I have allowed this port to communicate via Diablo II’s Battlenet and Windows Sevices svchost on Windows 7. Port 6666 has a sweet tooth for port 4444, another one that has been used for malicious hacks. Please take note, that I do not look at this port lightly, because…anything is possible…
