Hi all, When using a public DNS, there is huge catch for not playing so well with CDN. Is there a way to preserve the CDN by asking dnsmasq to send multiple resolve request to a few server instead of one, and return the IP with shorter route path.
It doesn't have to return immediately, but query the second one in another thread (just saying,) and after the other is proved nearer then update the entry in the cache. So that the client will get a better resolve result when the cache expires. I knew this could be done by using `--server` option to assign DNS server for a list of domains, but when there are thousands of domains need to be set this is a little painful. So I'm seeking for a better solution. Thanks, Xiaoyi PS: I don't have much options other than using a public DNS, since internet in China is highly censored, domains like google.com, twitter.com will be hijacked using ISP provided DNS. For example: root@OpenWrt:~# nslookup twitter.com 202.106.196.115 Server: 202.106.196.115 Address 1: 202.106.196.115 linedns.bta.net.cn Name: twitter.com Address 1: 59.24.3.173 root@OpenWrt:~# nslookup twitter.com 8.8.8.8 Server: 8.8.8.8 Address 1: 8.8.8.8 google-public-dns-a.google.com Name: twitter.com Address 1: 199.59.150.7 r-199-59-150-7.twttr.com Address 2: 199.59.149.230 www4.twitter.com Address 3: 199.59.150.39 r-199-59-150-39.twttr.com
