About:
ipv6calc is a command-line utility designed to calculate, manipulate, and convert IPv6 addresses. It provides robust functionality for generating addresses, performing prefix calculations, and converting between different IPv6 representations. The tool is essential for network engineers working with IPv6 address planning and diagnostics.
Key Features:
  • IPv6 address calculation and manipulation
  • Address format conversion (e.g., compressed, expanded)
  • Prefix and netmask computation
  • Database lookups for geolocation and registry data
Use Cases:
  • Converting IPv6 addresses between different formats for logging or configuration
  • Planning subnet allocations and calculating address ranges
  • Anonymizing IPv6 addresses in datasets for privacy compliance
Alternatives:
  • sipcalc – Sipcalc supports both IPv4 and IPv6, whereas ipv6calc focuses specifically on IPv6 features.
  • knot-dns – Knot DNS includes tools for DNS management but lacks the specialized IPv6 conversion features of ipv6calc.
