Frequently Asked Questions
Is this an exhaustive IANA service-name database?
No. It is a curated reference with many common ports, but not every row is a polished service mapping. Some entries are generic placeholders such as port-2483 when the table does not provide a more descriptive label.
Can I filter to only UDP ports or only dynamic/private ports?
Yes. There is a protocol dropdown for TCP, UDP, and TCP/UDP, plus range buttons for Well-Known, Registered, and Dynamic.
What exactly gets copied when I click a port row?
The tool copies a port/protocol token, not the whole description. For example, 443 becomes 443/tcp+udp and 22 becomes 22/tcp.
Why are app ports like 3000, 5000, and 8080 in a port reference?
This table intentionally mixes classic well-known ports with modern developer and infrastructure ports. That is why you will see entries for dev-server, app-server, Docker, Prometheus, Redis, and similar tooling.
Where does this tool consider the dynamic or ephemeral range to start?
It uses the standard split built into the component: 0-1023 is Well-Known, 1024-49151 is Registered, and 49152 and above is Dynamic.
