Netty 无法解析 DNS 名称

Question

我使用 Marketo 从我的 Java 应用程序发送电子邮件，我使用 WebClient 向 Marketo API 提交 REST 请求。最近发邮件开始抛异常，发现Netty抛出如下错误：

Received a mismatching DNS response: DatagramDnsResponse(from: /100.96.1.1:53, to: /0:0:0:0:0:0:0:0:50578, 19016, QUERY(0), NoError(0), RD RA)
        DefaultDnsQuestion(145-jnh-675.mktorest.com. IN A)
        DefaultDnsRawRecord(145-jnh-675.mktorest.com. 91 IN A 4B)

Received a mismatching DNS response: DatagramDnsResponse(from: /100.96.1.1:53, to: /0:0:0:0:0:0:0:0:50578, 24563, QUERY(0), NoError(0), RD RA)
        DefaultDnsQuestion(145-jnh-675.mktorest.com. IN AAAA)
        DefaultDnsRawRecord(mktorest.com. 122 IN SOA 52B)

如果我使用 dig 查询该 DNS 名称，我会得到一个 NOERROR 状态，那么为什么 Netty 会抛出这个错误？以下是 dig.

的输出

$ dig 145-JNH-675.mktorest.com

我能够根据此处的 Reactor Netty 问题更改默认 DNS 解析器来解决此问题 (https://github.com/reactor/reactor-netty/issues/1431)。

final var httpClient = HttpClient.create().resolver(DefaultAddressResolverGroup.INSTANCE)
final var webClient = WebClient.builder().clientConnector(ReactorClientHttpConnector(httpClient)).build()
