Important Command Prompt Commands in Packet Tracer

1. IP Configuration Commands

Used to verify IP addressing information:

ipconfig

ipconfig /all

ipconfig /release

ipconfig /renew

These commands help confirm whether the device has received the correct IP address, subnet mask, and default gateway.

---

2. Connectivity Testing Commands

Used to test communication between devices:

ping 192.168.1.1

tracert 8.8.8.8

• ping checks basic connectivity
• tracert shows the packet path across routers

---

3. ARP Command

Displays MAC-to-IP address mappings:

arp -a

This is useful for understanding Layer 2 to Layer 3 interactions.

---

4. Name Resolution Command

Tests DNS functionality:

nslookup google.com

Ensures DNS servers are resolving domain names correctly.

---

5. Network Statistics Commands

Used to view routing and connection details:

netstat

netstat -r
