How To Change Dhcp Ip Address In Windows 7
Not many users are aware that Windows 7 provides more than one manner to configure a workstation's network adaptor IP accost or strength it to obtain an IP address from a DHCP server. While the nigh pop method is configuring the properties of your network adaptor via the Network and Sharing Center, the less popular and unknown way for most users is using the netsh Command Prompt. In this tutorial, we evidence you how to employ the Command Prompt netsh command to speedily and easily configure your IP address or set information technology to DHCP. Competent users can also create simple batch files (.bat) for each network (e.g abode, work etc) and then they can execute them to quickly make the IP address, Gateway IP and DNS changes.
In order to successfully modify the IP address via Command Prompt, Windows vii requires the user to accept administrative rights. This ways even if you are not the administrator, you must know the administrative password, since you volition be required to utilize the administrative command prompt.
Opening The Administrative Command Prompt on Windows seven
To open up the authoritative command prompt in Windows 7, first click on the Start icon. In the search dialog box that appears, blazon cmd and right-click on the cmd search result displayed. On the menu that Windows brings up, click on the Run as administrator option every bit shown in the below screenshot:
Effigy 1. Running CMD as Administrator
Depending on your User Account Control Settings (UAC), Windows may inquire for confirmation. If this happens, simply click on Yep and Windows volition present the CLI prompt running in elevated administrator privileged fashion:

Using The 'netsh' Control Prompt To Change The IP Accost, Gateway IP and DNS
At the Authoritative Command Prompt, blazonnetsh interface ip testify config, which will display the network adapters bachelor on your arrangement and their names. Annotation down the name of the network adaptor for which you would like to set the static IP accost.
Effigy iii. Finding Our Network Adapter ID
In our case, we'll be modifying the IP address of the interface named Wireless Network Connexion, which is our laptop's wireless network card.
Fifty-fifty if the Wireless Network Connexion is gear up to be configured via DHCP, we can still configure a static IP accost. Following is the command used to configure the interface with the IP address of 192.168.5.50 with a subnet mask of 255.255.255.0 and finally a Gateway of 192.168.5.1:
C:\Windows\system32> netsh interface ip gear up address "Wireless Network Connexion" static 192.168.5.50 255.255.255.0 192.168.5.ane
Side by side, we configure our primary DNS server using the netsh command with the following parameters:
C:\Windows\system32> netsh interface ip set dnsserver "Wireless Network Connection" static 8.viii.8.8
Note: When entering a DNS server, Windows will try to query the DNS server to validate it. If for whatever reason the DNS server is not reachable (therefore not validated), yous might see the following error:
The configured DNS server is incorrect or does non exist
To configure the DNS server without requiring DNS Validation, use the validate=no parameter at the end of the command:
C:\Windows\system32> netsh interface ip prepare dnsserver "Wireless Network Connection" static eight.eight.8.8 validate=no
This command forces the DNS server setting without any validation and therefor no fault will exist presented at the CLI output in case the DNS server is not reachable.
To verify our new settings, use the netsh control with the following parameters:
C:\Windows\system32> netsh interface ip testify config
At this indicate, we should run across the network settings we configured, equally shown beneath:
Figure 4. Verifying Our New Network Settings
Using The 'netsh' Control Prompt To Fix The Network Interface Card to DHCP
You can use the netsh command to switch your electric current adapter from static to DHCP. To switch your network adaptor from static IP configuration to DHCP, use the following command:
C:\Windows\system32>netsh interface ip set address "Wireless Network Connection" dhcp
Windows will not return any confirmation subsequently the control is entered, nevertheless if the network adaptor has successfully obtained an IP address and has Net connexion, there should not be any network icon with an exclamation mark in the taskbar notification area every bit shown beneath:
Figure v. Wireless Icon with no Assertion Marking
Finally, to verify that DHCP is enabled and we've obtain an IP accost, use the netsh control with the post-obit parameters:
C:\Windows\system32> netsh interface ip prove config
This commodity showed how to configure a Windows 7 network interface with an IP accost, Gateway and DNS server, using the Administrative Command Prompt. We too showed how to set a Windows 7 network interface to obtain an IP address automatically from a DHCP server.
