Mastering essential network commands is crucial for IT professionals to troubleshoot, secure, and optimize networks. Below are key commands with practical examples and use cases.
Windows Network Commands
1. `ipconfig` – View Network Configuration
Displays IP address, subnet mask, and default gateway.
ipconfig /all
– Use Case: Verify DHCP-assigned IP or detect IP conflicts.
2. `nslookup` – Query DNS
Resolves domain names to IP addresses and checks DNS records.
nslookup example.com
– Use Case: Troubleshoot DNS resolution failures.
3. `ping`, `tracert`, `pathping` – Diagnose Connectivity
- Ping: Tests reachability.
ping 8.8.8.8
- Tracert: Traces the route to a host.
tracert google.com
- Pathping: Combines ping + tracert with latency stats.
pathping 192.168.1.1
4. `netstat` & `arp` – Monitor Connections
- Netstat: Lists active connections.
netstat -ano
- ARP: Displays the ARP cache (IP to MAC mapping).
arp -a
5. `getmac` & `hostname` – Device Identification
- Getmac: Lists MAC addresses.
getmac /v
- Hostname: Shows the computer name.
hostname
6. `net use` & `net share` – Manage Shared Resources
- Net Use: Connects to shared folders.
net use Z: \server\share
- Net Share: Lists shared resources.
net share
Linux Equivalent Commands
1. `ifconfig` / `ip` – Network Configuration
ip a ifconfig -a
2. `dig` / `host` – DNS Lookup
dig example.com host example.com
3. `ping` & `traceroute` – Connectivity Testing
ping 8.8.8.8 traceroute google.com
4. `ss` / `netstat` – Active Connections
ss -tulnp netstat -tuln
5. `arp` – ARP Cache
arp -n
