Changing your IP address can be useful if you want to avoid being attacked by other users who are targeting your IP address, or if you simply want a new online identity from an IP standpoint. You can change your IP address on a Mac at any time through System Preferences.

Choose your computer’s operating system.

For Windows XP:

Step 1

Click Start->Control Panel->select and double click Network and internet connections->select and double click Network Connections.

Step 2

Double-click the Local Area Connection icon; highlight Internet Protocol (TCP/IP) tab in the Local Area Connection Properties window that appears:

So DHCP is running but I still need static IPs that don't change. To achieve this in Windows Server DHCP configuration I need to find the leases, right click and convert them to static reservations. Then under reservations if I look at the properties I see that now my client will always get a static IP. (If the IP address, host name, and domain name have been previously set, these will be overwritten by the setting values obtained from DHCP, BOOTP, RARP, or Auto IP.) If you use DHCP without the DNS dynamic update function, it is recommended that an identical IP address be assigned to the machine at all times.

The Mac OS is not seeing or communicating with the DHCP server in the router. Try setting it to manual, and putting in the router/gateway address (192.168.1.1) and a manual address for the Mac (192.168.1.109 for example - whatever is not taken by the other devices.). The next time you are provisioning a server or workstation, use PowerShell to configure a static IP and DNS servers. If the computer ultimately should use DHCP, use PowerShell to remove the static configuration and revert to DHCP. Technet.microsoft.com Net TCP/IP Cmdlets in Windows PowerShell.

Step 3

Double click it or click Properties. The TCP/IP Properties window will display.

Step 4

Now you have two ways to configure the TCP/IP protocol below:

1. Assigned by DHCP Sever

Select Obtain an IP address automatically and Obtain DNS Server address automatically, as shown in the figure below. These may be selected by default. Then click OK to save setting.

2.Assigned manually

1) Select Use the following IP address, as shown in the following figure.

If the router’s LAN IP address is 192.168.10.1, please type in IP address 192.168.10.x （x is from 2 to 253）, subnet mask 255.255.255.0, and default gateway 192.168.10.1.

2) Select Use the following DNS server addresses, as shown in the following figure. And then type the DNS server IP address, which should be provided by your ISP. Finally remember to click OK to save settings.

Note: In most cases, type your local area DNS server IP addresses into it.

The Preferred DNS server is same to default gateway. For Secondary DNS server, you could leave it blank or type in 8.8.8.8.

Step 5

Click OK to save and apply your settings.

For Windows Vista & Windows 7

Step 1

Click on windows key+ R key on the keyboard at the same time.

Step 2

Type ncpa.cpl in the box, then press OK.

Step 3

Select the local area connection, right click it and select Properties.

Step 4

Select Internet Protocol Version 4(TCP/IPv4), double click it or click Properties.

1. Assigned by DHCP server

Select Obtain an IP address automatically and Obtain DNS server address automatically. If necessary, then click OK to save the settings.

2. Assigned manually

1) Select Use the following IP address, type IP address, subnet mask and default gateway IP address into it.

If the router’s LAN IP address is 192.168.10.1, please type in IP address 192.168.10.x （x is from 2 to 253）, subnet mask 255.255.255.0, and default gateway 192.168.10.1.

2) Select Use the following DNS server addresses, as shown in the following figure. And then type the DNS server IP address, which should be provided by your ISP. If necessary, then click OK to save the settings.

Note: In most cases, type your local area DNS server IP addresses into it.

The Preferred DNS server is same to default gateway. For Secondary DNS server, you could leave it blank or type in 8.8.8.8.

Step 6

Click OK to save and apply your settings.
