关于Android应用支持IPV6
今天看了一些关于Android应用关于支持IPV6的问题，简单记录
ipv从地址来说比v4多了“[]”，长度更长
1. 正常来说OKHttp，XUtils等上层网络框架是支持ipv6的。但是如果你的应用中用到了socket，比如长连接，或者是直接用socket进行数据传输等，这时就需要进行ipv6的适配了。后面适配时再补充
2.Glide关于ipv6的支持。看到了https://www.jianshu.com/p/c8ebb4a3cc76。这篇文章介绍了绕过的方法，但看了glide的源码，发现有些不同，可能是版本不一样导致。问题原因确实如注释所写
* To obtain a properly escaped URL, call {@link #toURL()}. To obtain a properly escaped string
* URL, call {@link #toStringUrl()}. To obtain a less safe, but less expensive to calculate cache
* key, call {@link #getCacheKey()}.
但是去Glide源码中去找使用的地方，也就是register地方（这个过程可以参考上面链接内容）

} 都是在这里确定的register，然而这里的register没有用到toStringUrl，都是toUrl、getCacheKey,因此我觉得新版glide已经支持ipv6了
