Local Network Adapter Configuration (One Network Card)

For your local network adapter, it is recommended that you accept the default values.

If the network adapter was already assigned an IP address, that information was used as the default value. Otherwise, the network adapter was assigned a default IP address of 192.168.16.2 and a subnet mask of 255.255.255.0. The default values are private IP addresses, which help to secure your local network.

Private IP addresses cannot be routed on the Internet and must be routed through a server using network address translation (NAT), which is provided by Windows Small Business Server.

Notes

  • Windows Small Business Server requires a static IP address for the network adapter used to access your local network.
  • If the network adapter was already assigned an IP address that was routable (public IP address), it is recommended that you change it to use a non-routable (private IP address). For more information, see the following section.

Changing the default values

If you want to use a different IP address and subnet mask, consider the following:

  1. The IP address you select must be valid. A valid IP address cannot be 0.x.x.x, 169.254.x.x, or 127.0.0.1, and it cannot exceed the 223.x.x.x range.
  2. It is strongly recommended that you not use a public address, or routable IP address. If you decide to do so, first obtain an address from your Internet service provider (ISP).
  3. It is recommended that you configure your local network to use one of the following private address blocks, as specified in RFC 1918:
    • The 192.168.0.0/16 private network allows the following range of valid IP addresses: 192.168.0.1 to 192.168.255.254.
    • The 172.16.0.0/12 private network allows the following range of valid IP addresses: 172.16.0.1 to 172.31.255.254.
    • The 10.0.0.0/8 private network allows the following range of valid IP addresses: 10.0.0.1 to 10.255.255.254.
