What happens when DHCP pool is full?
DHCP has determined that a scope is nearing capacity. If the scope becomes full, the DHCP server cannot lease additional IP addresses. Client computers that cannot obtain new leases from the DHCP server will not have network connectivity.
So here's my understanding of the situation: when a DHCP server runs out of leases to assign, it will kill the oldest (in terms of use) lease. If the device that held the lease is not on, for relevant values of "on", at the time, it will not be notified about this.
If you are considering multiple DHCP servers, remember that multiple DHCP servers cannot share any of the same addresses. If you use more than one DHCP server in your network, each server must be configured with their own unique IP address ranges.
A DHCP error means the server on your network that provides an Internet Protocol address for devices isn't able to assign your computer an IP address. Because the DHCP setting can break the internet connection, the error can appear in many forms, but the end result is that you can't access the internet.
- Add a new gateway to the appropriate interface (192.168. 3.1/24) for example and add another DHCP server.
- Change the gateway on the existing to the /23 as you mentioned and then modify the DHCP range.
A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.
What happens when we run out of IP? There'll simply be more IP addresses created, most likely before the existing ones run out.
The Internet Assigned Numbers Authority (IANA) believes that it will still be able to reclaim enough to IPv4 addresses to avert any calamity. But the only long term solution is to implement IPv6 across the Internet, and soon. IPv6 addresses present themselves as four dotted quads of numbers, e.g. 1234.5678.
- Click the Tools tab.
- Choose the DHCP Scope Monitor available under the Address Monitoring category.
- Specify the Name or the IP Address of the DHCP Server.
- Specify the SNMP Read Community of the DHCP Server.
- Click Get DHCP Scope Details.
You can run two DHCP servers on the subnet and let one distribute addresses .
How many clients can a DHCP server handle?
By default, there is no limit to the number of DHCP local server or DHCP relay clients allowed on an interface. However, you can override the default setting and specify the maximum number of clients allowed per interface, in the range 1 through 500,000.
The DHCP Server Multiple Subnet feature enables multiple disjoint subnets to be configured under the same DHCP address pool. This functionality enables the DHCP server to manage additional IP addresses by adding the addresses to the existing DHCP address pool (instead of using a separate address pool).

Turn off the DHCP client computer in conflict with the network device that has the static IP address. On the DHCP server, exclude the static IP address from the scope of the DHCP IP address range. Restart the DHCP client computer.

To remove a scope from a superscope, open the DHCP console and open the superscope in question. Right-click the scope and choose Remove from Superscope.
If you see a 169.254. x.x address, it means that the DHCP server is not reachable. The PC will not work because there is not a router to or from that PC. Troubleshoot this by finding out why the PC cannot see the DHCP server.
- Go to Control Panel.
- View network status and tasks under Network and Internet.
- Select Ethernet or Wifi (highlighted in blue), which ever you are connected to.
- Click on Details in the window that pops up.
- Look to see if DHCP Enabled says Yes.
- Then close out of the screens.
The Current index column shows the next IP address that will be assigned by the DHCP server. Under normal operation, we would expect to see and IP address within the 192.168. 7.0 network, however the value of 0.0. 0.0 means that there are no more available IP addresses to lease.
