dnsmasq 缓存不生效

[qsnow6]

在 mac 上用 brew 安装好了 dnsmasq，经过一翻配置。折腾完了，但是测试后发现，并没有缓存成功。以下是 2 次 dig 日志

这是啥原因？ dig 显示的 server 地址表示已经解析成功了，但是为什么没有缓存？

[crysislinux]

生效了，129 变成 128 了

[qsnow6]

@crysislinux #1 不是看 Query time 吗

[crysislinux]

query time 确实不太好。但是那个时间感觉就是再算 ttl

[param]

我是緩存清不掉。。

设置 min-cache-ttl=3600

效果:

有没有开启客户端缓存服务？

[qsnow6]

@krisbai #6 这个配置是开启了吗

resolv-file=/usr/local/etc/resolv.dnsmasq.conf
strict-order
cache-size=32768
listen-address=127.0.0.1

[q0000x]

@qsnow6 少了 min-cache-ttl=3600 这个配置，3600 是秒

[taobibi]

@qsnow6 listen-address=0.0.0.0
这样其他设备都能解析
cache-size=32768
min-cache-ttl=3600

用 all-servers，并发查询多个 dns，优选最快的
