What is the difference between superscope and multicast scope

Any option you configure at this level will override any option configured at the server and scope levels. To configure a client option, right-click the client reservation and select Configure options. Be sure you are familiar with the order in which scope options are applied. The order is server, scope, class, and then client. You can see all the available DHCP options through the Properties dialog box for the server, scope, class, or client reservation see Figure 3.

DHCP options. Specifies the name resolution type. Most of the options outlined in Table 3. By doing so, any options configured on the DHCP server are overwritten by those configured locally. Aside from a regular scope, you can also create a second type of scope known as a superscope.

In a multinetted environment one that has multiple logical IP subnets defined on a single physical network , superscopes allow a DHCP server to assign leases to clients on multiple subnets.

For example, a physical network is divided into two subnets, Subnet A and Subnet B, connected by a router. Subnet B contains two multinets. The scope configuration on the DHCP server could be similar to the following:. One of the biggest advantages of creating superscopes is to ease administration of a multinetted environment.

Identifying which scopes go with which networks can be a difficult administration task. Creating superscopes and grouping scopes in some logical manner can make them easier to administer; for example, grouping all the scopes from a single floor in a large office building into a superscope eases the administration process.

When more than one logical IP network is used on each physical subnet or network, such configurations are called multinets. The New Superscope Wizard opens. Keep in mind that the superscope option is available only if a regular scope already exists. Type a descriptive name for the superscope something that makes it easy to identify. From the list of available scopes, select those to include in the superscope.

You can only add active scopes. After the superscope has been created, it must be activated by right-clicking the scope and selecting the Activate option. Multicasting is the process of sending a message to a group of recipients as opposed to unicasting , in which a message is sent to a specific recipient. Windows extends the functionality to allow you to create multicast scopes so that messages destined to a multicast IP address can be sent to all clients in a multicast group.

The server is also responsible for maintaining the group membership list and updating the list as members join and leave a group. The New Multicast Scope Wizard opens.

Configuring a range of multicast addresses. Specify a lease duration, which defines how long a client can lease a multicast address from the scope.

Multicasting provides a one-to-many relationship and is often used for applications such as live media streaming or video conferencing. See Figure 3. On the Multicast Scope Name page, type a name for the multicast scope and a description if desired. Click Next. Download Microsoft Edge More info.

Contents Exit focus mode. Superscopes can resolve certain types of DHCP deployment issues for multinets, including the following situations: The available address pool for a currently active scope is nearly depleted, and more computers need to be added to the network.
