Our virtual hosts are divided into two categories

1. Shared virtual host -- -- does not support universal resolution binding

2. Exclusive virtual host -- -- Support universal resolution binding (universal resolution to IP is supported without binding)

About the exclusive host domain name universal resolution binding instructions:

Because the exclusive host has exclusive IP resources, it only needs to resolve the domain name to the IP address of the host. It does not need to bind the domain name to support all domain name access.

Universal parsing format:

1. Top level domain name resolution: fill in the host value @ type select A record record value fill in the host IP

2. Second level domain name resolution: fill in the host value * type selection A record record value fill in the host IP
