An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [ 1 ][ 2 ] IP addresses serve two main functions: network interface identification, and location addressing. Internet Protocol version 4 (IPv4) defines ...
e. QUIC (/ kwɪk /) is a general-purpose transport layer network protocol initially designed by Jim Roskind at Google. [1][2][3] It was first implemented and deployed in 2012. [4] It was publicly announced in 2013 as experimentation broadened, and was described at an IETF meeting. [5][6][7][8] QUIC is used by more than half of all connections ...
BitTorrent, also referred to simply as torrent, is a communication protocol for peer-to-peer file sharing (P2P), which enables users to distribute data and electronic files over the Internet in a decentralized manner.

IP address blocking or IP banning is a configuration of a network service that blocks requests from hosts with certain IP addresses. IP address blocking is commonly used to protect against brute force attacks and to prevent access by a disruptive address. It can also be used to restrict access to or from a particular geographic area; for ...

The pseudo-header consists of the source IP address, the destination IP address, the protocol number for the TCP protocol (6) and the length of the TCP headers and payload (in bytes). Urgent pointer (16 bits) If the URG flag is set, then this 16-bit field is an offset from the sequence number indicating the last urgent data byte.
Pieces 0, 1, 8, 9 have availability 1. Pieces 2, 3, 6, 7 have availability 2. Pieces 4 and 5 have availability 3. The entire torrent has availability 1.6 (1 + 6/10). The integer part is 1 because 1 is the lowest piece availability. The fractional part is 6/10 because more than one peer has pieces 2 to 7 (6 pieces) and there are 10 total pieces.
A torrent file contains a list of files and integrity metadata about all the pieces, and optionally contains a large list of trackers. A torrent file is a bencoded dictionary with the following keys (the keys in any bencoded dictionary are lexicographically ordered): announce —the URL of the high tracker. info —this maps to a dictionary ...
