I have an overseas websites have been use free CloudFlare CDN, but was later found in the country is slow, so want to use a domestic CDN, later, I saw this post, want to set the mixture of CDN,

My plan is to put the database, servers are moved to ali cloud, at home and abroad are using the same database + + domain name server, and access to domestic use ali cloud CDN acceleration, foreign access to or use CloudFlare CDN acceleration,

But in that case diagram wiki above, I am not very understand what 104.27.177.110 and 59.110.190.55 respectively represent, why the two IP address?

If I ali cloud server IP address is aaa. The BBB. CCC. DDD, where should I write it?
