我这里能测试出缓存行为:

felix@flygon ~ {0}$ dig www.acfun.com | grep time
;; Query time: 3 msec
felix@flygon ~ {0}$ dig www.acfun.com | grep time
;; Query time: 0 msec

(任何表内域名都是这样)

恩所有域名都是这样,刚知道DNS也有TTL……dnsmasq好像会从upstream dns里获取这个TTL,怎么让它们时间变长一些呢 > <

不建议更改 TTL, 因为设置不长的 TTL 是有原因的... 事实上只要一过 TTL 就变 IP 的 网站/CDN 还是挺常见的.

我办公室还好,114和8888的延迟分别是20ms和50ms,回去之后是长宽……

local-ttl max-ttl max-cache-ttl auth-ttl 居然都没有用
原来cache默认150也是有原因的..
