移除 UtilIPv6AutoConfiguration 配置类，将里面的配置移动到 NacosDiscoveryAutoConfiguration 可能会比较好一些

按你的方案进行修改，应用启动一会儿就会闪退，原因是NacosServiceManager被创建出两个实例，其中一个实例的nacosDiscoveryProperties属性值为空，导致NPE异常闪退。
请问NacosServiceManager需要多实例吗？

我这边基于 nacos-discovery-consumer-example 测试并未复现，移除 UtilIPv6AutoConfiguration 后，需要同时移除 META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports 里面相关的配置

集成org.springframework.cloud:spring-cloud-starter-config就会出现异常。
UtilIPv6AutoConfiguration用到的地方移除了。

我看了下 InetIPv6Utils 的引用，只有在 discovery 模块中用到，2022和2023版本目前在挺多项目中有集成，有可能是你项目中的一些个性化配置导致了这个问题

在集成SpringCloud Config配置服务时客户端不启用其discovery能力，即spring.cloud.config.discovery.enabled=false 是可以正常启动的。
目前我们是把SpringCloud Config服务注册到Nacos，其他服务通过Nacos来发现配置服务。
spring.cloud.config.discovery.enabled=true

Summary
LGTM — small, focused fix. Adding UtilIPv6AutoConfiguration to @ImportAutoConfiguration ensures the InetIPv6Utils bean is available in the bootstrap context. This resolves the missing bean issue for IPv6 environments.
