The 129 IPv6 network masks, indexed by prefix length — `IPV6_MASKS[64]` is the mask for a `/64`.

**Signature:**

```typescript
IPV6_MASKS: bigint[]
```

## Remarks

The IPv6 counterpart of [IPV4\_MASKS](https://imqueue.org/api/net/latest/net.ipv4_masks/): index 0 is `0n` and index 128 is all ones, giving 129 entries. Same caveat — a mutable exported array that should be treated as read-only.
