This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. ipaddr.isValid validates IPv4 and IPv6 string formats
  2. ipaddr.IPv4.isValid and ipaddr.IPv6.isValid validate specific IP versions
  3. ipaddr.parse parses IPv4 address into object with kind ipv4, octets array, and private range
  4. ipaddr.parse parses IPv6 address into object with kind ipv6 and normalized string representation
  5. ipaddr.parseCIDR and match evaluate CIDR subnet membership
  6. ipaddr.process correctly processes IPv4-mapped IPv6 addresses to IPv4
  7. ipaddr.parse throws error on invalid IP format
