Verify IP parameters on different OS

In this article I describe Verify IP parameters on different OS in networking for ccna. I can give you an overview of Verify IP parameters on different OS in networking for ccna, along with examples.

Verifying IP parameters on different operating systems involves using built-in commands to check network configurations, such as IP addresses, subnet masks, default gateways, and DNS servers. Here’s how you can verify these parameters on Windows, macOS, and Linux:

Windows

To verify IP parameters on a Windows system, you can use the ipconfig command in the Command Prompt.

Steps:

Open Command Prompt:

• Press Win + R, type cmd, and press Enter.

Enter the ipconfig command:

   ipconfig /all

Example Output:

Windows IP Configuration

   Primary Dns Suffix  . . . . . . . : your-domain.com
   Node Type . . . . . . . . . . . . : Hybrid
   IP Routing Enabled. . . . . . . . : No
   WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter Ethernet:

   Default Gateway . . . . . . . . . : 192.168.1.1
   DHCP Server . . . . . . . . . . . : 192.168.1.1
   DNS Servers . . . . . . . . . . . : 8.8.8.8
                                       8.8.4.4

macOS

To verify IP parameters on macOS, you can use the ifconfig and netstat commands in the Terminal.

Steps:

Open Terminal:

• Press Cmd + Space, type Terminal, and press Enter.

Enter the ifconfig command to check IP addresses:

   ifconfig

Enter the netstat -nr command to check the routing table (including default gateway):

   netstat -nr

Example Output:

ifconfig Output:
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether ac:de:48:00:11:22 
    inet6 fe80::aede:48ff:fe00:1122%en0 prefixlen 64 secured scopeid 0x7 
    inet 192.168.1.100 netmask 0xffffff00 broadcast 192.168.1.255
    nd6 options=201<PERFORMNUD,DAD>
    media: autoselect
    status: active

netstat -nr Output:

Linux

To verify IP parameters on a Linux system, you can use the ip command or the older ifconfig command, along with route or ip route.

Steps:

Open Terminal.

Enter the ip addr command to check IP addresses:

   ip addr

Enter the ip route command to check the routing table:

   ip route

(Optional) Use cat /etc/resolv.conf to check DNS servers:

   cat /etc/resolv.conf

Example Output:

ip addr Output:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:1a:2b:3c:4d:5e brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.100/24 brd 192.168.1.255 scope global dynamic eth0
       valid_lft 86398sec preferred_lft 86398sec
    inet6 fe80::21a:2bff:fe3c:4d5e/64 scope link
       valid_lft forever preferred_lft forever

ip route Output:
default via 192.168.1.1 dev eth0
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.100

cat /etc/resolv.conf Output:
nameserver 8.8.8.8
nameserver 8.8.4.4

Conclusion for Verify IP parameters on different OS

• Windows: Use ipconfig /all to see detailed network information, including IP addresses, subnet masks, gateways, and DNS servers.
• macOS: Use ifconfig for IP addresses and netstat -nr for routing information. The DNS servers can be found in the Network Preferences or by checking /etc/resolv.conf.
• Linux: Use ip addr and ip route for IP addresses and routing information, respectively. DNS servers can be checked with cat /etc/resolv.conf.

These commands provide comprehensive details about the network configuration on each operating system, helping to verify and troubleshoot IP parameters effectively.
