IP Address Configuration

Each computer on the network must have a unique IP address to send and receive data. If a Dynamic Host Configuration Protocol (DHCP) server is present on your network, you can use the IP Address Configuration page to have your server automatically obtain the IP address configuration from a DHCP server. Alternately, you can configure the IP address(es) manually.

In addition, you can specify one or more gateway addresses. A gateway address is the address of a local IP router residing on the same network as the server that is used to forward traffic to destinations beyond the local network. The value in each field must be a number from 0–255.

Note   Changing the IP address may cause clients to lose their connection with the server. To reconnect, clients must either use the new IP address or wait until the DNS server is updated.

To set or change the IP settings on the General tab

  1. On the primary navigation bar, choose Network.
  2. Choose Interfaces.
  3. Select the network connection you want to modify.
  4. In the Tasks list, choose IP.
  5. Select the General tab.
  6. Select whether to obtain the configuration automatically from the DHCP server, or to statically configure the IP address(es).
  7. If you choose to obtain the configuration from the DHCP server, choose OK.
  8. If you have chosen to use static IP settings, enter the IP address, Subnet mask, and Default gateway in the boxes provided.

To set or change the IP settings on the Advanced tab

  1. On the primary navigation bar, choose Network.
  2. Choose Interfaces.
  3. Select the network connection you want to modify.
  4. In the Tasks list, choose IP.
  5. Select the Advanced tab.
  6. In the IP address box on the right, type the IP address, and then choose Add.
  7. Type the appropriate mask information in the Subnet mask box.

    A subnet mask is a 32-bit number that is notated by using four numbers from 0–255, separated by periods. Typically, default subnet mask numbers use either 0 or 255 as values, such as 255.255.255.0. However, other numeric values can appear, indicating that the subnet is configured for a single TCP/IP network. This number, with a value other than 0 or 255, is combined with the IP address number to identify the network on which your computer resides.

  8. If necessary, update the IP Connection Metric.

    The metric indicates the cost of using the routes associated with this connection and becomes the value in the Metric column for those routes in the IP routing table. If there are multiple routes to a destination the route with the lowest metric is used. The default value is 1.

  9. Repeat steps 1–3 for any other IP addresses you wish to add.

To set or change the gateway address settings

  1. In the Gateway and Metric boxes, type the IP address of both the default gateway and the metric, and then choose Add.
  2. Repeat step 1 for each default gateway you want to add.
  3. When you are finished modifying the configurations on this screen, choose OK.
