<a name="route53_1_0-query-examples-sourceversion2"></a>

Amazon Route 53 解析程式查詢日誌會追蹤 Amazon VPC 內資源所做的 DNS 查詢。訂閱者可以查詢 Route 53 解析程式查詢日誌，以了解下列類型的資訊：

以下是AWS來源版本 2 的 Route 53 reesolver 查詢日誌的一些範例查詢：

**過去 7 天內來自 CloudTrail 的 DNS 查詢清單**

```
SELECT 
    time_dt,
    src_endpoint.instance_uid,
    src_endpoint.ip,
    src_endpoint.port,
    query.hostname,
    rcode
FROM "amazon_security_lake_glue_db_us_east_1"."amazon_security_lake_table_us_east_1_route53_2_0"
WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '7' DAY AND CURRENT_TIMESTAMP 
ORDER BY time DESC
LIMIT 25
```

**`s3.amazonaws.com`過去 7 天內符合的 DNS 查詢清單**

```

**過去 7 天內未解析的 DNS 查詢清單**

```
