Finding Your Internal IP (OS X 10.5 and Newer): Click on the Apple icon on the upper-left corner of. On Windows 10, you can find this information more quickly than you could on previous.
Configuring IP address in a Windows with CMD performed using netsh command line utility. The network shell (netsh) is a set of commands that help you configure any Windows operating system IP address, Network Interfaces, and Windows Firewall. The usage of the command line is for pro level Windows users. Those who are playing the network infrastructure configuration. But using the command line as normal Windows user indicate your expertise to Windows environment. If you are new to Windows command line, this article 'configure IP address with command prompt in Windows 10' will help you begin using command line interface.
Configuring Windows IPv4 Networking with Netsh or Network Shell. Netsh is a command-line utility included in Microsoft's Windows NT line of operating systems beginning with Windows 2000. It allows local or remote configuration of network devices such as the NICs.
Configure IP Address with Command Prompt in Windows 10
Before setting IP address with cmd in Windows 10, you need to know how to find your IP address on Windows 10. So before everything, you must know the network IP address configuration on your system.
Let's learn the process of IP configuration step by step. I am going to explain it with an easy pictorial guide. If you don't understand some part, just kindly comment us and ask your questions.
The process of Changing Windows 10 IP Address with Command Prompt:
- Find your IP address in Windows 10.
- View network interfaces card.
- Change IP address on Windows 10.
- Change DNS IP address with the command line.
- Reset IP address with Command Prompt.
How to Find your IP Address on Windows 10?
There are many options for finding IP address on Windows 10. The easy one is 'ipconfig' command. To find your IP address on Windows 10, just type 'ipconfig' in command prompt. To do this process:
- Press Windows+R keys to open the Run.
- Type 'cmd' in the run and press enter.
- Now type 'ipconfig' to show the IP address.
The 'ipconfig' command shows everything about your computer network interfaces. You might have many physical or virtual network interface card.
Here, I just have one network interface on my Windows 10 computer. The result of ipconfig command shows that the IP 169.254.29.130 with the mask of 255.255.255.0 is my current Windows IP address.
This is a class C 'autoconfiguration IPv4'. When your system doesn't find any DHCP Server or manual IP address, it obtains auto IP address. So let's change it.
How to Change IP Address with Command Prompt?
For change IP address, open command prompt or PowerShell. Both works the same and you can run all command prompt commends on Powershell as well. Ok, run cmd or Powershell as administrator. Netsh work in both command prompt and Powershell. I'm using Windows Powershell to change IP address on Windows 10 completely. Becuase the user interface and color's of Powershell is better than Command prompt.
- Type 'Powershell' in Windows 10 search box to run Windows Powershell.
- You need to run Powershell as administrator. Just press Windows+Shift the press enter to run Powershell as administrator. Or right-click the Powershell and click Run as administrator.
To find the network interface with the command line, type the following command on Powershell. Download the cheat engine for mac os x.
The result shows two network interfaces. The Loopback and the Ethernet. The Loopback is Windows builtin network loopback interface, but our pointed network interface is the ethernet.
To find your IP address in Windows 10 with netsh command, just type the following command.
It displays all the network interface configuration. The output result is clear and better than output result of 'ipconfig' command on Command prompt. So to find an exact information of the network interface, just add the index ID of the network interface at the end of the command.
That's good. Let's configure and change Windows 10 IP address with the command line. The command is bit long but easy to understand. No need to remember, just try to understand the netsh command structure.

To change the IP address of the 'Ethernet0' network interface, type the following command.
Once the command executed successfully, check the result with 'netsh interface ipv4 show config 2' command. Yes, the output result shows the exact IP address has set on the 'Ethernet0' network interface. Now the Windows IP address is 200.100.10.5 with the mask of 255.255.255.0 and default gateway is 200.100.10.1.
Note: You can't change the default gateway separately with the following command. It will remove the IP address and just set the default gateway address.
That's good and enough for IP address configuration in Windows 10 with the command line. Let's change DNS IP address from the command line.

How to Change DNS IP address from Command Prompt?
DNS IP address is the unique address in the network that resolves computer name to IP address and IP address to the computer name. In the network, finding a computer with a name is easy than 32-bit IPv4 address. To set or change the DNS IP address, just simply do it with the following command.
You might see some error on a simple local network, because of not having a DNS server. When you don't have a DNS server, it's not necessary to set DNS IP address on your computer.

Finally, recheck the result with 'netsh interface ipv4 show config 2' command. The output netsh command should be displayed with DNS IP address.
Final World
Configure IP address with command prompt in Windows has tow benefits. The first benefit of working with Windows command line helps get you improve your skills in Windows environment. The second benefit is command line is faster than GUI. If you work with the command line, you will understand the power of command line.
The Windows command line interface has improved a lot in Windows 10. Now you can find some Linux commands that run in Windows 10 and works the same on Linux. Finally, hope you learn how to configure IP address with Command Prompt in Windows operating systems.

As a Network Administrator/Engineer you may be asked to find MAC addresses and/or IP Addresses, hopefully this can make your job a little bit easier. These commands work on most Cisco Switches and Routers but sometimes the commands can vary from device to device.
5 Steps total
Step 1: Connect to your Cisco Devices
Connect to the Switch/Router by using a console cable or a terminal emulator like Putty or Secure CRT. If you are successful it should look something like this.
Step 2: Find The MAC Addresses
On the layer 2 device (switch) enter the username and password if needed. Next enter 'enable' mode on the switch by typing enable. Next type the command 'show mac address-table'. If successful it should look like the picture. It's worth noting that on some Cisco devices the command 'show mac-address-table' also works.
Step 3: Find the IP Address
On the layer 3 device ( L3 switch or router) in my case I am using a router, enter the username and password if needed. Next enter 'enable' mode on the router by typing enable. Next type 'show ip arp' if done correctly you should get an output similar to the picture.
Step 4: Filtering the results on a Router
In the example I have provided there were only 9 IP addresses. However in the real world there could be dozens or even hundreds of IP addresses. To help filter the results on a router type 'show ip arp ?' You will see gigabitethernet' as an option this will let you filter results by interface or sub-interfaces. In my exmaple it typed 'sho ip arp gigabitEthernet 0/0.10' and that listed all IP's on my sub-interface.
Step 5: Filtering the results on a Layer 3 Switch
As stated in Step 4, you will likely have more than 9 IP Addresses. This can be made worse in a messy closet with a 48 port switch running the closet and maybe even some layer 2 switches under that. Luckily in addition to being able to filter by interface you can also filter by VLAN. So type in 'show ip arp ?' and you will see 'vlan' as a listed filter. As you can see I typed in 'sho ip arp vlan 20' and it listed only those IP's in vlan 20. In this case it was the vlan interface and a PC.

Command For Mac Address To Ip
- AnaheimGDBJNC Apr 27, 2018 at 01:15pm
Great post.
Another way to find that information is to first PING the address of the system you are looking for. Then issue:
show arp | i .This will then show you the MAC address associated with the IP address.
Then issue:
show mac address-table | iThis will give you the port that the device is currently connected.

Thanks for posting this *after* I finished a 'What's Connected Where' jihad on our network. :^D After beating Google to death over it, hoping for some useful tool, I ended up using exactly the same process (plus the online MAC address lookup to ID the device manufacturer), so I can affirm this works perfectly, if you work it.

As you can see, the 'sh arp' or 'sh ip arp' commands also give you the MAC addresses, so essentially the 'sh mac add' is only to get the port in which the device is connected. It helps to Ping the subnet's broadcast address (e.g. '10.1.1.255') to load the ARP table. (Small tip: When you see a large number of MAC addresses showing up on a single port, there's a switch on that port into which those MAC addresses are connected. If you're all Cisco, 'show cdp neighbor' (or 'sh cdp nei') will get you to the next switch. Also, 'sh ip arp | i 0/24' will show just the MAC address(es) on that port.)
The amazing thing to me is, this far into the 21st Century, this is still the only way I could find to get this information -- i.e. to find out what's connected where. Did I mention it's a *lot* of work?
(ETA: What if you can't get to the Console port? How do you get the IP address of the switch in order to SSH or (if you must) Telnet in?)

Good stuff, thanks for posting this! My go-to Cisco command is: show ip interface brief (show ip int bri). Another thing I've learned that is very helpful (I'm still a noob with Cisco stuff) is tab-completion and using a '?' after the start of a command, such as 'show ?'
- CayenneEd Rubin Apr 27, 2018 at 03:09pm
Unfortunately dumping the mac table and working through it is the only way to reliably find stuff and identify its switch port. I've done a similar process with HP switches. One thing that helps a lot is an ip scanner application that does MAC vendor ID lookups for you. This can help with jim6795's problem of identifying an undocumented switch IP since you can look for the the switch maker's vendor ID and then try ssh or telnet, or http/https depending on the product.

Spiceworks has the ability to harvest this information using SNMP and will create a map showing which device is on which switchport. It must have the correct MIB installed for your switch and you must configure SNMP. The feature could use some more work but basic components are there.

Couldn't you just use CDP? #show cdp nei detail will show you the ip of the connected devices.

Hey everyone thanks for the great feed back, it's really cool having this featured. @SadTech0 if you cant to the console port and you don't know the IP Address you could use a tool like angry IP scanner and find the switch that way. CDP may or may not work depending on your network configuration and/or topology. Barring some major obstruction you should try to console in get the ip and start an inventory. Hope that helps.
- Thai PepperTodd_in_Nashville Apr 30, 2018 at 12:34pm
Keep in mind, in some security minded environments, CDP may be disable if it's not needed. It's one of those things that give out unnecessary reconnaissance info to the bad guys. If one of your edge routers gets compromised, it can be used to start footprinting your internal network.
- Thai PepperJohn3367 Apr 30, 2018 at 08:51pm
Great info.
Another helpful thing you should add!
SHOW INVENTORY ---> To show the SERIAL number of the Cisco device you are on.
**I always use those commands you show to troublshoot. They are very helpful. I usually PING an IP address. then I type a 'show arp' and get its MAC address. then I will type 'show mac-address table' which will show me which PORT the device is connected to!
