To condense an IPv6 address, you can omit leading zeros in each 16-bit block and replace contiguous blocks of zeros with a double colon (::), but this can only be used once in an address. For example, the address "2001:0db8:0000:0000:0000:0000:0000:0001" can be condensed to "2001:db8::1". This makes the address shorter and easier to read while maintaining its uniqueness.

Peer review is a process used to evaluate the quality and credibility of academic work, such as research papers or articles, before they are published. In this process, experts in the same field assess the work for its methodology, accuracy, and contribution to the discipline. Peer review helps ensure that published research meets established standards and is free from significant errors or biases. It serves as a quality control mechanism in scholarly communication.

A serial network is a type of communication architecture where data is transmitted sequentially over a single channel or line, one bit at a time. In this setup, devices are connected in a series, meaning that each device must wait for the previous one to finish transmitting before it can send its data. This contrasts with parallel networks, where multiple bits are transmitted simultaneously over multiple channels. Serial networks are often used for long-distance communication due to their simplicity and reduced cost in wiring.

The original language of "Ip Man 2" is Cantonese. The film, which is a sequel to the 2008 movie "Ip Man," features dialogue primarily in Cantonese, reflecting the cultural and linguistic context of the story set in Hong Kong.

Hijacking in a peer-to-peer (P2P) attack refers to the unauthorized takeover of a user's connection or session within a P2P network. Attackers may exploit vulnerabilities to intercept or manipulate data exchanged between peers, potentially gaining access to sensitive information or altering transactions. This type of attack can compromise the integrity and confidentiality of the network, leading to data theft or unauthorized actions. Effective security measures, such as encryption and authentication, are essential to mitigate these risks.

"Make default" refers to the action of setting a specific option, setting, or preference as the standard or automatic choice in a system or application. When something is marked as default, it is automatically selected or applied unless the user specifies otherwise. This can apply to software settings, file formats, or various configurations in devices, streamlining user experience by minimizing the need for repeated selections.
