The basic protocol used on the Internet is the Internet Protocol (IP), which is usually coupled with additional protocols such as TCP (Transmission Control Protocol [2]) or UDP (User Datagram Protocol). TCP/IP is the protocol set used for email and web browsing. Each protocol has a block of information, called a header, included near the front ...
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
QUIC has been specifically designed to be deployable and evolvable and to have anti-ossification properties; [31] it is the first IETF transport protocol to deliberately minimise its wire image for these ends. [32] Beyond encrypted headers, it is 'greased' [33] and it has protocol invariants explicitly specified. [34]
The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
To avoid this method of cheating, the lockstep protocol requires each player to first announce a "commitment" (e.g. hash value of the action); this commitment is a representation of an action that: Cannot be used to infer the action; and; Easily compares whether an action corresponds with a commitment.

[8] Despite the similar name, this function is entirely unrelated.
