yes, one can configure two dhcp server on a same network. But for doing this, one has to define different scopes in both dhcp server in order to avoid ip address conflict. Eg. one can configure a scope for a lan with network address of 10.0.0.0 as- 10.0.0.10- 10.0.0.100 in one dhcp server.
while other scope would be 10.0.0.101-10.0.0.200 . In this way we can have to dhcp servers on a same network. Which ever dhcp server receives the request for the ip address will provide the ip address.
IN case for servers, one can use mac bindingin both servers so that they obtain same ip address

What is persistent ip?
Persistent IP is when the DHCP server is configured to give you the same DHCP Address every time. So you have the same IP Address without having to configure your IP Address and network settings manually.
Who is server for dhcp?
It is what... DHCP is designed to automatically distributed IP addresses to connected to the same network devices.
You have installed and configured a dhcp server on your network. you also have a web server on the same network. The web server requires the same ip address as the dhcp server what should you do?
The only way that could work is if the DHCP service and the HTTP service were configured and running on the same physical machine. Otherwise they could not use the same IP address. DHCP and HTTP do not have to be on separate machines (but it is a good idea to separate them in a network). A better question might be why the two services *require* the same IP address.
In the Absence of dhcp server which ip client will receive?
A DHCP server will privide a client with a valid IP address for the network for which the DHCP server is providing a service.Where there is no DHCP server the IP address for a client must be set manually. When doing this care must be taken to ensure that two IP addresses are not set the same on the network.
The DHCP relay agent capability is built into which role in Windows Server 2008?
, the DHCP relay agent is now available under the Network Policy Server. When installing this role, select a role service "Routing and Remote Access" to be installed. The rest is the same like in Windows Server 2003 - just configure it using RRAS administrative console.
How can you give private ip on a LAN?
The same as a public IP. Your choices are: (1) assign an address manually, and (2) configure the computer to get an IP address automatically from a DHCP server.The same as a public IP.

Can DNS and DHCP both be on one server?
Absolutely. If you are running a Windows server, configure the DNS and DHCP Server settings in [Start] [Administrator Programs]. If you have a *nix server, configure the named and dhcpd daemons. In either case, if you are running a single-server scenario, there are many advantages to running both DHCP and DNS on the same box. For example, if your local domain is set to something like "example.local", your PCs in the network would have names like accounting.example.local, server.example.local, and so on. By having both services configured together, you will be able to address your local network by the computer name ("accounting" or "ScottsDesktop", etc), without the "example.local". If you are running Small Business Server, I think you *must* use both DNS and DHCP on that server, integrated into Active Directory.
What is scope and super scope?
A DHCP scope is a valid range of IP addresses which are available for assignments or lease to client computers on a particular subnet. In a DHCP server, you configure a scope to determine the address pool of IPs which the server can provide to DHCP clients. Scopes determine which IP addresses are provided to the clients. Scopes should be defined and activated before DHCP clients use the DHCP server for its dynamic IP configuration. You can configure as many scopes on a DHCP server as is required in your network environment Using superscopes A superscope is an administrative feature of DHCP servers running Windows Server 2003 that you can create and manage through the DHCP console. Using a superscope, you can group multiple scopes as a single administrative entity. With this feature, a DHCP server can:Support DHCP clients on a single physical network segment (such as a single Ethernet LAN segment) where multiple logical IP networks are used. When more than one logical IP network is used on each physical subnet or network, such configurations are often called multinets.Support remote DHCP clients located on the far side of DHCP and BOOTP relay agents (where the network on the far side of the relay agent uses multinets).In multinet configurations, you can use DHCP superscopes to group and activate individual scope ranges of IP addresses used on your network. In this way, the DHCP server computer can activate and provide leases from more than one scope to clients on a single physical network. Superscopes can resolve certain types of DHCP deployment issues for multinets, including situations in which: The available address pool for a currently active scope is nearly depleted, and more computers need to be added to the network. The original scope includes the full addressable range for a single IP network of a specified address class. You need to use another IP network range of addresses to extend the address space for the same physical network segment.Clients must be migrated over time to a new scope (such as to renumber the current IP network from an address range used in an existing active scope to a new scope that contains another IP network range of addresses).You want to use two DHCP servers on the same physical network segment to manage separate logical IP networks.Superscope configurations for multinets The following section shows how a simple DHCP network consisting originally of one physical network segment and one DHCP server, can be extended to use superscopes for support of multinet configurations. Example 1: Non-routed DHCP server (before superscope) In this preliminary instance, a small local area network (LAN) with one DHCP server supports a single physical subnet, Subnet A. The DHCP server in this configuration is limited to leasing addresses to clients on this same physical subnet. The following illustration shows this example network in its original state. At this point, no superscopes have been added and a single scope, Scope 1, is used to service all DHCP clients on Subnet A. Example 2: Superscope for non-routed DHCP server supporting local multinets To include multinets implemented for client computers on Subnet A, the same network segment where the DHCP server is located, you can configure a superscope which includes as members: the original scope (Scope 1) and additional scopes for the logical multinets for which you need to add support (Scope 2, Scope 3). This illustration shows the scope and superscope configuration to support the multinets on the same physical network (Subnet A) as the DHCP server. Example 3: Superscope for routed DHCP server with relay agent supporting remote multinets To include multinets implemented for client computers on Subnet B, the remote network segment located across a router from the DHCP server on Subnet A, you can configure a superscope which includes as members: the additional scopes for the logical multinets for which you need to add remote support (Scope 2, Scope 3). Note that since the multinets are for the remote network (Subnet B), the original scope (Scope 1) does not need to be part of the added superscope. This illustration shows the scope and superscope configuration to support the multinets on the remote physical network (Subnet B) away from the DHCP server.
Why do you think the IP addresses are different but the subnet masks and default gateways are the same?
Because you have a DHCP server in the network.
How many IP addresses does a remote access server lease from a DHCP server at one time?
Usually only one. A DHCP server is a Dynamic Host Control Panel, which assigns an IP to a network device. It will only give you one, and everyone using that network device will also have the same IP.
What features allows a host to be configured through Dhcp while still retaining the same IP address?
At the DHCP server, you would create an address reservation. To do so, you need to know the host's MAC address for its network interface.
What problems occurs when dhcp server go down?
Then any computer that is turned on - while the DHCP server is down - can't get an IP address, and therefore can't communicate on the network. Also, a DHCP lease may expire - the computer got the IP address for 24 hours, for example, and the time elapses. Same problem.
