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
- ipKeyGenerator returns IPv4 address strings unchanged without modification
- ipKeyGenerator applies default /56 subnet masking to IPv6 addresses and returns CIDR notation
- ipKeyGenerator applies custom subnet masking (e.g. /64, /32) when ipv6Subnet number is specified
- ipKeyGenerator returns the full IPv6 address without subnet masking when ipv6Subnet is false
- ipKeyGenerator normalizes IPv4-mapped IPv6 addresses (::ffff:x.x.x.x) to clean IPv4 address strings
