IP地址列表体积会不小的,占用空间会很多,对于CGN网络下,IP地址列表可能无效,没有判断的途径。
这样做的原因是什么?检测耗时,耗CPU?

IP地址列表也可以在程序安装的时候或者运行的时候动态下载。只是觉得本地判断下总应该比实际测速要来得快,SmartDNS的目的不就是为了极致的速度么。这功能可以在配置文件里加开关的,由用户自己决定是否开启。CGN网络如果不适用就在配置文件里禁用就好了。

我想了一下,对于你说的这个方案,没有特别好的办法。
IP地址库不容易处理,并且后面IPV6的话,基本就不可行了。即使下载也会占用很大的存储空间。
还有,现在大部分用户其实都是CGN网络了,如果大部分用户都不用这功能的话,价值就不是很大了。
所以,目前暂不考虑你的这个建议。
如果是为了DNS解析速度的话,可以强制将TTL调大,这样smartdns就会一直缓存。查询的时候,直接内存返回结果了。

好吧,我也只是个脑洞给个建议,不好使就算了吧

#以下分别把下载好的运营商IP集写入到ipset,对应ipset名称为 chnroute/telecom/mobile和unicom,可自行修改
##电信IP

ipset flush telecom
ipset -N telecom nethash
for network in cat $ROUTES
; do
ipset -A telecom $network

##移动IP
ROUTES=/etc/routeIP/mobile.txt
ipset flush mobile
ipset -N mobile nethash

##联通IP

ipset flush unicom
ipset -N unicom nethash

##国内IP

得到的ipset可以用到负载均衡插件的规则里

Release 18优化了响应时间,在测速的情况下也能保证响应时效。
可以获取验证。
Release 18也新增了ipset的支持,有需要可以使用。

好的,已更新
