1.14.0-beta17
描述

前提条件是tun中adress选项为"172.18.0.1/30", "fdfe:dcba:9876::1/126"时

  1. 当我的网络环境只有ipv4时，即使我在dns.strategy中设置prefer_ipv4，direct流量依然返回AAAA解析结果，导致连接失败，只有将dns.srategy设置为ipv4_only时，或者将tun中的ipv6地址删除，才会正确的使用A解析。
    以下是错误日志内容
connection: open connection to [240e:950:400::7ce2:4824]:443 using outbound/direct[DIRECT]: dial en0 (5): dial tcp [240e:950:400::7ce2:4824]:443: connect: no route to host
  1. 当我将tun中的IPV6地址删除，在ipv6环境下derect流量可以正常连接，但部署在ipv6服务器上的Naiveproxy节点无法连接，除了naiveproxy之外其他的协议(目前我测试过的有anytls, vless, tuic, hysteria_v1, hysteria_v2, shadowsocks+shadowtls)可正常连接

Research direction

Start by reproducing the direct-outbound IPv6 selection with the supplied DNS strategy and TUN address configuration, then inspect the DNS resolution and direct dialing entry points. Compare behavior with prefer_ipv4, ipv4_only, and without the TUN IPv6 address; done means direct traffic uses a reachable address in IPv4-only networks while IPv6 direct and Naiveproxy connections continue to work.
