dynamic ports

Dynamic ports are temporary TCP/IP ports assigned by Windows for client-side communications. In Windows Vista and Windows Server 2008, Microsoft increased the default dynamic port range from 1025-5000 to 49152-65535. This change helps avoid port exhaustion in high-traffic environments. Administrators can view or modify the dynamic port range using the `netsh int ipv4 set dynamicport` command. The setting is stored in the registry, and users on Windows 7 or later can adjust the range as needed. Understanding dynamic ports is important for network troubleshooting, firewall configuration, and enterprise IT management.
