Where should DHCP servers be located?
DHCP servers should be located on at least one subnet on a LAN in a routed network. When the server needs to support clients on remote subnets separated by routers, the router should be RFC 1542–compliant, or a DHCP Relay Agent should be used to support forwarding DHCP traffic between the subnets.
Does DHCP server need to be on same subnet?
Not really, unfortunately. On the same subnet, you absolutely cannot run two DHCP servers that assign addresses from the same range. However, on the same subnet, you can have two DHCP servers that assign addresses from different ranges.
Is subnetting possible in DHCP?
Another aspect of DHCP that’s important to understand is that the protocol utilizes broadcasts from client to the server in order to find the DHCP server and initiate the request. But on very large networks with hundreds or thousands of different IP subnets, it would be impossible to maintain a DHCP server per subnet.
Is DHCP bad for gaming?
In some cases, reserved IP will also provide higher priority to the networks, and it is suggested that you check it with your internet service provider. On the other hand, DHCP might lead to network issues because gaming is one activity that cannot experience network and internet lags.
How does a DHCP server connect to a subnet?
So you can either configure relay agent (ip helper) on router interfaces connected to your new networks or connect DHCP server to each new subnet directly using additional NICs on DHCP server. Since you mention that there will be routing between all subnets, then you need to configure IP helper address on router interfaces to point to DHCP server.
Is it possible to set up two DHCP servers?
It’s not recommended to do, but if you must do it, set up a subnet with double the addresses you need, then set each server up with different scopes, each taking half of the available addresses in the DHCP pool. If each building needs to pull addresses from their own server, then they should each be their own subnet, with a router in between them.
How to change the subnet mask of a DHCP scope?
To guide you in calculating the IP range, several calculators are available on the Internet: List the equipment with fixed IP addresses to change the subnet mask. Check the routing equipment (Routers / Switchs / Firewall ….). Reduce the duration of DHCP leases on the beach.
Do you need a SuperScope for two DHCP servers?
You don’t mention what DHCP server you are running, but if Windows and you really want to use 2 subnets, then you need what is called a superscope. By using a superscope, you can group multiple scopes as a single administrative entity.
