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.

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