What is Common Ports?
Ports identify services within a single machine: 80 for HTTP, 443 for HTTPS, 22 for SSH, 5432 for PostgreSQL, and so on. Knowing the common ports speeds up configuring servers, firewalls and deployments.
This reference gathers the most common TCP/UDP ports with the service running on each, so you don't have to look them up when opening a firewall, connecting to a database or diagnosing a network issue.
