Reliable DHCP Management

Many service providers use DHCP to dynamically assign addresses to customer routers. It’s a business-critical service that comes with its own set of headaches:

  • Initial DHCP setup requires in-depth configuration expertise and detailed knowledge
  • Updating DHCP configurations is time-consuming & error prone, particularly for organisations with complex provisioning requirements. A single misconfiguration could bring down your network.
  • Information about which addresses are in use and the remaining available address space can be difficult to obtain or unclear. Without visibility, it’s impossible to plan and control your IP address space effectively.
  • There is no historical insight on IP leases or finding relevant information takes hours
  • Server maintenance tasks such as updating software generally requires rebooting the server, and impact any time-critical applications that rely on DHCP
  • Updating software can break existing configurations files. Fixing the fault is by trial-and-error and can take a long time.
  • In split-scope networks, multiple DHCP servers share the same data in different databases making the service vulnerable and difficult to manage due to updates regarding each server’s view of the network
  • Configuring a reliable failover mechanism is really difficult. But without failover, DHCP server failure leads to network downtime and time-consuming data retrieval.

For those with complex provisioning requirements, manually administering DHCP creates a heavy workload and a dedicated DHCP appliance can help:

  • simplify or automate initial configuration and day-to-day administration
  • provide a high level of resilience and availability
  • improve performance with an optimised hardware / software combination
  • improve visibility & control of IP address usage
  • integrate with billing systems through APIs

Handling DHCP within an integrated DDI solution like DNSBOX will keep workload to a minimum and ensure consistency of data between DNS, DHCP and IPAM.

Just need DHCP? We’ve perfected the dedicated DHCP server
User feedback has always rated the DNSBOX DHCP solution highly. With increasing need for stand-alone DHCP, in 2021 we decided to re-build it from the ground up, to build indisputably the world’s best DHCP server. Informed by expert customer insight every step of the way, that’s what we’ve done.

DHCP-Screenshot-subnetsEasier to deploy and use

Automation tools reduce the steps required for initial and ongoing configuration including setting up subnets, leases and views. Network administrators will be able to configure DHCP services in less time than with manual processes. For example, setting up Failover DHCP takes 2 minutes with a DDI tool, whereas it can take hours to write correct config files.

With a user interface between the administrator and the server, data editing can be performed in clear, logical steps making these tasks more intuitive. Validation allows administration to be safely delegated to junior team members.

Visibility of your IP usage

When auditing your IP addresses, you want the full picture of your network:

  • Accurate information on which subnet is serving DHCP services
  • Current and historical lease data – which IPs are leased to which clients and how they are being used
  • How much of your address space is currently allocated to clients

DHCP-Screenshots-lease-statisticsWith a dedicated appliance, you can get a holistic, live view of your DHCP service’s IP address usage through easy to read graphical reports and clearly presented configuration details for each address. This allows you to control IP address allocation effectively and put a plan in place to cater for CPE leaving and joining your network.

Where you have multiple distributed servers, some DDI solutions like DNSBOX give you aggregated visibility of your entire DHCP service from a centralised interface.

DHCP-Screenshot-failover‘Always On’ DHCP

Ensuring maximum availability of this critical network service is a top priority.

Validation tools can eliminate the configuration errors that would threaten the stability of your DHCP service. If a proposed configuration contains conflicts or unacceptable values, the tool refuses to implement changes and provides a detailed description of which data is invalid and why.

Having a backup plan for your DHCP service further protects your network from costly failures. An appliance can make it much easier to configure DHCP failover pairs. With just a few clicks, you can set up processes that synchronise data between servers and configure the parameters for your failover mechanism.

Some DDI solutions like DNSBOX let you schedule firmware upgrades at times when critical applications are least likely to be affected.
