    可以用maradns、Windows server入面果個DNS、Synology果個DNS、仲有其他software,上圖係個原理。

My DNS server resolved www.facebook.com to IP 173.252.110.27 which has relatively high ping at around 250. May need to play with GeoDNS to solve this lol

    HKBN用ISP DNS都正常ping,但自建就有問題。

    Is the ISP of your server same as that as your residential broadband?
It may cause problem if the ISP of the user is not the same as that of the DNS resolver.
Some connections(e.g. akamai, some other CDN providers, some other ICP providers like Google) may be less efficient because some ICP have IPs from each ISP and answer DNS queries with the IPs in the corresponding ISPs.

In my case, Facebook still works well but with high ping.
