Server Connection
Name Resolution
Name resolution converts the textual domain name into an IP address and port number.
When initiating a connection, a client should acquire the A, AAAA, CNAME, and SRV records for the domain.
CNAME Records
If a CNAME is found, the server should resolve the name until A or AAAA records are found.
SRV Records
SRV records allow a service to associate a domain name with the hostname and port number used to access the service.
