No
We can install 2 DHCP server or more, There is no IP conflict because we can define different IP range scope on individual DHCP server. Techie Sep 26th, 2007 Yes, we can have as many multiple DHCP servers, as it can asign IPs from the same scope are different scope. Depends upon the requirement. Like we can have some thing called as stand-by server or secondary server incase the primary fails. No we can't have 2 DHCP servers in one network, coz it is used to provide IP address to the clients. If two server are supposed to distribute at a time there will be a conflict of the given and reserved IP addresses between two distribution points.

If the router / layer 3 switch separating them can act as a BOOTP/DHCP relay agent, then you can continue to keep all your DHCP server(s) in one or two central parts of your network and configure your DHCP server(s) to support multiple ranges of addresses. From the server’s point of view, each server will have a pool of addresses that it can issue to clients, known its address scope. DHCP servers that are serving the same subnet should not have a single “shared” scope, but rather they should have a “split” scope. A DHCP (Dynamic Host Configuration Protocol) server can provide IP addresses to clients spanning multiple subnets if the router that separates them can act as an RFC 1542(BOOTP) relay agent. If the router cannot function as relay agent, each subnet that has DHCP clients requires a DHCP server. When you have multiple DHCP servers, Microsoft recommends that you place your DHCP servers on different subnets to achieve a degree of fault tolerance, rather than having all the DHCP servers in one subnet. If this is what you want then you can simply configure each DHCP server as a standalone server, with the details of the address pool for its own subnet, and not worry about any other DHCP servers on other parts of the network. This is the most basic example of having more than one DHCP server on the same network. From the server’s point of view, each server will have a pool of addresses that it can issue to clients, known its address scope. DHCP servers that are serving the same subnet should not have a single “shared” scope, but rather they should have a “split” scope. When most people ask about “multiple DHCP Servers on the same network”, what they are usually asking for is this; they want more than one DHCP server issuing the same range of network addresses out to clients, either to split the load between multiple servers or to provide redundancy if one server is offline. From the server’s point of view, each server will have a pool of addresses that it can issue to clients, known its address scope. DHCP servers that are serving the same subnet should not have a single “shared” scope, but rather they should have a “split” scope. If you've got two (2) DHCP server computers in the same layer 2 broadcast domain, clients are going to be (mostly) randomly assigned addresses by either server computer. The one that answer's the client's DHCPDISCOVER reuqest first is going to end up assigning the address to the client. In an AD, you can have multiple redundant DHCP servers, and you can configure them to manage the same scope without overlapping addresses. You can also configure reservations and several other things. If you have multiple subnets in your network, and do not have a DHCP server on every subnet, determine whether your current routers relay DHCP/BOOTP messages. If your routers cannot be used for DHCP/BOOTP relay and you choose not to configure DHCP/BOOTP relay agents, you must configure your network so that a DHCP server has a network adapter on each subnet it serves. So if you have two separate configurations you want to push via DHCP, you can't do it predictably if both DHCP servers are on the same network-not to mention if the IP ranges overlap, you'll have IP conflicts. Short answer: no, you cannot bridge two DHCP servers together. Computers that join the network would get an address from whichever router that responded first, and the two routers would not check in on each other.
