Ali cloud cloud analytical DNS can set up the binding domain name, IP

CodePudding user response:

1. The DNS record resolution to public IP
2. In what are you doing on the gateway of the mapping, the public IP port 80 is mapped to a VIP on port 80

In that case, it is suggested that gives no one VPS public IP, then the elastic public IP tied to the VIP, or simply SLB,
