题主,我在维基百科上搜的 example 是二级域名呀。

域名发散是 PC 时代的产物,而现在进入移动互联网时代,通过无线设备访问网站,App的用户已占据了很大一部分比重,而域名发散正是在这种情况下提出的。
应该是“而域名收敛正是在这种情况下提出的。”

大佬好,小白一个
我看到字节跳动的dns解析出来的ip一大坨。
那么app假使访问一个域名接口,最后是怎么知道去访问哪个ip,还是说默认取第一个?

这可能是用到了DNS负载均衡技术,主要有两种技术:
-
DNS轮询,DNS会根据权重(默认权重1:1:1),轮询这些A记录,依次返回3个IP地址。
-
DNS分区,根据你的LocalDNS的地区和线路,返回对应的IP地址
