Well, it does about as much as say, when Congress names an Aircraft Carrier, or ISO some day publishes C++ 23 (probably later this year).
Concretely your Linux systems probably have a file named /etc/services which maps the string "doom" to port number 666, much as it maps "ssh" to 22 or "http" to 80.
Yes, it means that you can reliably expect most UNIX/Linux systems (possibly even most OSs with IP stacks) to resolve the port "doom" to 666.

None of mine do, but now I'm going to add this.
