### Problem
On the **dev (current)** and **4.x** trees, every example on
`ipv6_cidr_to_range` wraps the input in `INET6_ATON('...')`. The value
`INET6_ATON` returns is rejected by `ipv6_cidr_to_range`, so on both
**4.1.1**
and **master** the examples error instead of producing the documented output:
```
SELECT ipv6_cidr_to_range(INET6_ATON('2001:db8::1'), 64);
ERROR 1105 (HY000): errCode = 2, detailMessage =
(127.0.0.1)[INVALID_ARGUMENT]Invalid IPv6 value
```
The 2.1/3.x docs use the working `to_ipv6('...')` form.
### Fix (dev + 4.x, EN + ZH)
- `INET6_ATON(...)` → `to_ipv6(...)` so the examples run.
- `` as range `` → `` as `range` `` — `range` is a reserved keyword and
otherwise
fails to parse (`mismatched input 'range'`).
- ZH `/48` example: the expected `max` was truncated by one group
(`2001:db8:1:ffff:ffff:ffff:ffff` →
`2001:db8:1:ffff:ffff:ffff:ffff:ffff`); the
EN doc was already correct.
### Verification
Ran every example on the page end-to-end against a live **Apache Doris
4.1.1**
cluster (dev tree verified against it too): all pass. The `/48` range now
returns
the full address on both languages:
```
SELECT ipv6_cidr_to_range(to_ipv6('2001:db8:1::1'), 48) as `range`;
+---------------------------------------------------------------------+
| {"min":"2001:db8:1::", "max":"2001:db8:1:ffff:ffff:ffff:ffff:ffff"} |
+---------------------------------------------------------------------+
```
The out-of-range example still raises `Illegal cidr value '129'` as
documented.
