subdomains for the same IP with different ports !!!!

i know that it is not possible to configure dns that give  subdomains for the same ip but with differents ports Ex.:
alfa.example.com  10.10.10.1 :550
beta.example.com 10.10.10.1  :560
because  DNS only provides names and  addresses - no port numbers.
for that  i want a  solution or scenario to resolve this case
the subdomains are not for  web application all of them ,  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 .
maybe  the solution is by setting up proxy servers for those  addresses. They can proxy requests  or  setting up server for the ports that can  provide them to the client
so can u please help me  with the best solution if it is possible.
Best  Regards

thank you in  advance

What you want to do is called an SRV record, and no one uses it.

There's no solution for your problem.

Implementing SRV on the serverside is great, but the client must support it also

Can the usual DNS cache work with the srv recorde server in the same way it does with the remote DNS server or does it need a specified DND cache ?

thanks for replay
