Create or Change a DHCP options set

Amazon recommends that you create a DHCP options set for your Amazon Directory Service directory and assign the DHCP options set to the VPC that your directory is in. This allows any instances in that VPC to point to the specified domain and DNS servers to resolve their domain names.

For more information about DHCP options sets, see DHCP options sets in the Amazon VPC User Guide.

To create a DHCP options set for your directory

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. In the navigation pane, choose DHCP Options Sets, and then choose Create DHCP options set.

  3. On the Create DHCP options set page, enter the following values for your directory:

    Name

    An optional tag for the options set.

    Domain name

    The fully qualified name of your directory, such as corp.example.com.

    Domain name servers

    The IP addresses of your Amazon-provided directory's DNS servers.

    Note

    You can find these addresses by going to the Amazon Directory Service console navigation pane, selecting Directories and then choosing the correct directory ID.

    NTP servers

    Leave this field blank.

    NetBIOS name servers

    Leave this field blank.

    NetBIOS node type

    Leave this field blank.

  4. Choose Create DHCP options set. The new set of DHCP options appears in your list of DHCP options.

  5. Make a note of the ID of the new set of DHCP options (dopt-xxxxxxxx). You use it to associate the new options set with your VPC.

To change the DHCP options set associated with a VPC

After you create a set of DHCP options, you can't modify them. If you want your VPC to use a different set of DHCP options, you must create a new set and associate them with your VPC. You can also set up your VPC to use no DHCP options at all.

  1. Open the Amazon VPC console at https://console.amazonaws.cn/vpc/.

  2. In the navigation pane, choose Your VPCs.

  3. Select the VPC, and then choose Actions, Edit VPC settings.

  4. For DHCP options set, select an options set or choose No DHCP options set, and then choose Save.
