FAQ
Why are ports in the 49152-65535 range recommended?
Under IANA rules, 49152-65535 is reserved for dynamic/private ephemeral usage, avoiding conflicts with privileged services in lower ranges.
Can I generate multiple non-conflicting ports simultaneously?
Yes. You can generate sets of distinct, unique ports for deploying multi-service Docker Compose networks without collision.
Does generating ports require system administrative rights?
No. The generator operates strictly in your browser as a randomizer tool without touching operating system sockets.
