A-records cannot specify a port or a specific URLwhere the request will be sent.

A record of type A (Address) contains the IP address of the server from which the domain or subdomain should be opened. Only IPv4 address can be used as an address.

In case of adding several A-records for one name, a random record will be given (DNS Round-Robin) from those added. In some cases, this allows you to configure a primitive load balancer.
