Networking Ports aur Protocols
Networking me ports aur protocols ka bahut bada role hota hai. Ports 0 se 65535 tak hote hain aur inko 3 categories me divide kiya jata hai:
âš¡ Port Categories:
Well-Known Ports (0-1023) – Common services ke liye reserve hote hain (jaise HTTP, FTP, SSH, etc.).
Registered Ports (1024-49151) – Specific applications aur software vendors use karte hain.
Dynamic/Private Ports (49152-65535) – Temporary connections ke liye use hote hain.
🔥 Common Networking Ports aur unke Protocols
(Yeh kuch important ports aur unke associated protocols hain👇)
Port | Protocol | Service |
|---|---|---|
20, 21 | TCP | FTP (File Transfer Protocol) – File transfer ke liye |
22 | TCP | SSH (Secure Shell) – Secure remote login ke liye |
23 | TCP | Telnet – Remote login but insecure |
25 | TCP | SMTP (Simple Mail Transfer Protocol) – Emails bhejne ke liye |
53 | UDP/TCP | DNS (Domain Name System) – Domain ko IP me convert karta hai |
67, 68 | UDP | DHCP (Dynamic Host Configuration Protocol) – IP auto assign karta hai |
69 | UDP | TFTP (Trivial File Transfer Protocol) – Simple file transfer |

5432 | TCP | PostgreSQL – PostgreSQL database ke liye |
5900 | TCP | VNC (Virtual Network Computing) – Remote desktop sharing |
8080 | TCP | Alternative HTTP – Web services |
🔥 Dynamic & Private Ports (49152-65535)
Ye ports temporary ya ephemeral connections ke liye use hote hain.
Jab koi application client-server communication karti hai, toh yeh ports dynamically assign hote hain.
Example: WebRTC, gaming servers, VoIP applications.
Kuch common dynamic ports jo use hote hain:
| Port | Use Case |
|---|---|
| 49152 | Windows RPC Dynamic Port |
| 49153 | MacOS Server Dynamic Port |
| 49154 | Cisco UCM (Unified Communications Manager) |
| 49155 | VMware ESXi Management |
| 49156-49158 | Microsoft Exchange |
| 49160-49180 | Skype, Microsoft Lync |
| 49400-49999 | Palo Alto Networks Firewalls |
| 50000 | Iperf (Network Testing Tool) |
| 50001 | SAP Message Server |
| 50002 | World of Warcraft Server |
| 50050-50051 | gRPC (Remote Procedure Calls) |
| 50500 | IBM Tivoli Storage Manager |
| 55000-55500 | Game Servers (Minecraft, CS:GO, etc.) |
| 60000-61000 | High-Performance Computing (HPC) |
🔥 TCP & UDP Ports List (0-65535)
Networking me TCP (Transmission Control Protocol) aur UDP (User Datagram Protocol) dono important roles play karte hain.
TCP – Reliable, connection-oriented protocol hai. (Example: HTTP, SSH, FTP)
UDP – Fast, connectionless protocol hai. (Example: DNS, VoIP, Streaming)
