its possible to configure dns that give subdomains the same ip but with differents ports mean
alfa.example.com 10.10.10.1 :550
beta.example.com 10.10.10.1 :560
the subdomains are not for web application all of them , cuz some of them are been used for terminal machine, other for mail server and others. for this reason, i need different port and i dont want to make the port fixed in the local machine
i want all possible scenario if possible
thx for reply .
