    The input file (usually a PCAP file containing GIPD output) to be decoded.

The gipddecode command is a utility used to decode the output of the Global IPv6 Prefix Decoder (GIPD). GIPD is a tool used to discover IPv6 prefixes delegated to a network. gipddecode takes the raw output from GIPD, typically captured in a PCAP file, and translates it into a human-readable format, making it easier to analyze and understand the discovered IPv6 prefixes and related information like MAC addresses and timestamps.

By parsing the GIPD output, gipddecode allows network administrators and security professionals to identify the IPv6 prefixes assigned to devices or networks of interest. This is particularly useful for network reconnaissance, security auditing, and troubleshooting IPv6 network configurations. Understanding the IPv6 prefix delegation helps in mapping network topology and identifying potential security vulnerabilities.

gipddecode relies on the specific output format of GIPD. Changes to the GIPD output format may render gipddecode ineffective until it is updated to accommodate the new format. The accuracy of the decoded information is directly dependent on the quality and completeness of the GIPD output.

The input_file should be a PCAP (packet capture) file that contains the raw network traffic captured by GIPD. The PCAP file can be created using tools like tcpdump or wireshark. gipddecode parses the packet data within the PCAP file to extract and decode the GIPD output.
