Some people just want to fix a DHCP headache. They find standard ISC DHCPd implementations unsatisfactory:
- Ensuring a reliable, highly available service by implementing DHCP failover is difficult
- Optimising hardware and software configuration to handle large numbers of DHCP leases
- This is a particular challenge for fast growing service providers or those who provide managed services to enterprises
- The difficulty of deploying and administering DHCP can be a further reason why you are looking for something better
DDI appliances in general help solve DHCP problems. If you are just focused on DHCP and need a high availability or high performance solution, then ones like DNSBOX – which include purpose-built solutions dedicated to DHCP – are ideal.
