Why would you create an IP address exclusion on a DHCP server?
An exclusion range is a set of one or more IP addresses, included within the range of a defined scope, that you do not want to lease to DHCP clients. Exclusion ranges assure that the server does not offer to DHCP clients on your network any addresses in these ranges.
What is IP reservation in DHCP?
A DHCP reservation is a permanent IP address assignment. It is a specific IP address within aDHCP scope that is permanently reserved for leased use to a specific DHCP client. Users can configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address assignment.
What is exclusion range?
An exclusion range is defined as a start/end IP address pair within an ipam/range object and is considered a sub-object within a regular DHCP range. IP addresses residing within the exclusion range are excluded from the pool of available IP addresses and are un-leasable.
Which ports are required for DHCP failover?

| Port Number | Protocol | Use |
|---|---|---|
| 647 | TCP | DHCP failover |
| 694 | UDP | xHA (heartbeat) |
| 847 | TCP/UDP | DHCP failover |

What is the purpose of the DHCP protocol?
Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.
What is a DHCP scope?
A scope is a consecutive range of IP addresses that a DHCP server can draw on to fulfill an IP address request from a DHCP client. By defining one or more scopes on your DHCP server, the server can manage the distribution and assignment of IP addresses to DHCP clients.
Why to use DHCP?
DHCP is also useful if an administrator wants to change the IP addresses of a large number of systems. Instead of reconfiguring all the systems, he can just edit one DHCP configuration file on the server for the new set of IP addresses.
How is the DHCP lease renewal process works?
How the DHCP Lease Renewal Process Works . The DHCP client renews its IP configuration data prior to the expiration of the lease time. If the lease period expires and the DHCP client has not yet renewed its IP configuration data, then the DHCP client loses the IP configuration data and begins the DHCP lease generation process again.
Is there a benefit using DHCP?
One main advantage of using DHCP is that DHCP servers greatly reduce the time required to configure and reconfigure computers on your network.
Is DHCP required for Active Directory?
If a DHCP server is improperly configured, then the clients that receive incorrect IP address configuration data from this DHCP server will also be also incorrect. Active Directory is required to authorize a DHCP server. With Active Directory, unauthorized DHCP servers will not be able to support DHCP clients.
