Summary of DHCP server features

In network design, we usually combine multiple hardware settings to build a complex network. In this process, we will also work with Multiple Protocol applications to manage networks. Here we will introduce the new features of the DHCP server. I hope the summary in this article will be helpful to you.

Automatically assigned IP Address

When the DHCP server of the Windows2000 DHCP workstation cannot provide a lease, it can assign a temporary IP address for itself. The DHCP workstation tries to communicate with the server every five minutes in the background to obtain a valid lease.

Enhanced Performance Monitoring and server reporting capabilities

The new performance monitoring counter allows users to observe the performance of DHCP servers on the network more clearly. The DHCP Manager uses a graphical display of the server, range, and current state of the customer to enhance the server's reporting capability. For example, it uses different icons to indicate whether the server or range is linked, A warning symbol is used to indicate that 90% of leases have been used.

Extended scope: Multi-address broadcast domain, super Scope

The new multi-access broadcast domain allows the DHCP workstation to use Class d ip addresses (224.0.0.0 to 239.255.255.255 ).

Super scope: it is very useful for creating a management group with a range of members. When you want to redefine a range or extend a range, it does not interfere with the scope of ongoing activities.

Option classes defined by users and service providers

Users can use this feature to assign appropriate options for similar users. For example, you can set users on the same floor to the same option class with the same class ID value. In years, you can use this class to allocate other option data during the lease process, and overwrite any range or global default options. It allows customers of class members in the same network to use more appropriate options.

DHCP and DNS integration

With Windows2000, the DHCP server can dynamically update the name space of the client in the DNS. range customers can use dynamic DNS to update their host name-IP address ing information in the DNS. Unauthorized DHCP Server Detection

The DHCP Client searches for the DHCP server in the form of limited network broadcast during login, which effectively prevents unauthorized DHCP servers from joining the network to an existing Windows2000 DHCP server.

Illegal DHCP Server Detection

The DHCP Client discovers the DHCP server through a limited network broadcast at startup, this feature effectively prevents unauthorized DHCP servers from joining the Active Directory-based Windows 2000 network. It is automatically disabled before an invalid DHCP server causes network problems.

Dynamic Support for BOOTP customers

The DHCP server provides better support for BOOTP users in large enterprise networks through the dynamic BOOTP attached. Dynamic BOOTP is an extension of the BOOTP protocol. It allows Dynamic Allocation of IP addresses like DHCP without having to use fixed addresses.

Access the DHCP Manager using the read-only console

When installing the DHCP service, a local group with special purposes-DHCP user group is automatically added, members in this group can access the DHCP manager on the server in read-only mode without the administrator.
