最近正好手头有一块树莓派闲着，寻思拿来当个内网的 DHCP 服务和 DNS 缓存提升一下上网体验，部署完成后，出于对配置项不熟，懵逼状态下加了个 domain=xxxxx.com 的搜索域（ xxxxx.com 只是手动马赛克掉自己的域名，这域名要真是我的...不敢想、不敢想），使用一切也正常，但是今天一翻日志，发现很多莫名其妙的域名查询不知道是哪来的，来请教一下各位。客户端是 win10，试了一下 ping pvdpyzybnhez 能造出类似的记录，可是翻遍了内网也没这么个主机名。

另外还有个比较奇葩的但好歹看起来正常的查询请求 wpad.xxxxx.com ，隔几个小时就请求一次。
Sep 7 23:46:50 dnsmasq[7971]: query[A] wpad.xxxxx.com from 192.168.3.96
Sep 7 23:46:50 dnsmasq[7971]: forwarded wpad.xxxxx.com to 114.114.114.114
这个翻了翻，可能是 win10 的自动代理发现 wpad，但看了设置里自动代理发现是关的，一样的懵。
