Clarkesville sees the DNSBOX light

December 16, 2014

ApplianSys is pleased to announce that CDE Lightband, an ISP in Tennessee, has bought a DNSBOX solution to provide more reliable services to its growing customer base.

Clarkesville Department of Electricity Lightband provides electricity and telecommunications services to over 60,000 customers.  Its current DDI system was approaching end-of-life and had been the cause of several issues for Network Operations Manager Ervin Evangelista.

The roll-out of CDE Lightband’s Fibre-to the-Home (FTTH) service to around 15,000 customers had proven particularly difficult to manage: maintaining visibility and control of IP leases and configuring DHCP options was a massive headache for Ervin. Customers suffered too as the company’s DNS servers were overloaded, causing timeouts and leading to complaints.

The ISP expects to double its FTTH subscriber-base over the next 5 years, so simplifying DNS management and providing a more robust, highly available DHCP service has become business-critical. Comparing alternative solutions, Ervin decided that ApplianSys’ DNSBOX was ideal, providing all the functionality he needed at a surprisingly affordable price.

CDE Lightband will deploy a DNSBOX400 master and a pair of DNSBOX200 slaves at the central core.  The DNSBOX200 units provide two critical benefits for CDE:

A high performance DHCP service with reliable failover for high availability, without all the usual headaches of trying to implement DHCP failover.

Secure DNS caching with load–balanced clustering for higher performance.

DNSBOX Sales Executive Ross Horn comments: “CDE needed a reliable DHCP service without the admin headaches of their old system. DNSBOX200’s DHCP functionality makes DHCP tasks easy for them e.g. configuring and managing multiple DHCP scopes – with different rules per scope – takes a fraction of the time the old system did.  It also allows them to create different user groups so that DDI tasks can be delegated efficiently.  And, if DNS and DHCP services grow in future, DNSBOX200s can easily be scaled – very affordably – to handle higher loads.”


CDE Lightband began operations in December, 1938. It provides internet, electric, digital and telecommunication services to over 60,000 customers in the Clarksville, Tennessee area. 892 miles of power lines and 960 miles of fibre optic cable are maintained.

A board of five local business people, appointed by the mayor and city council, governs the policies of CDE Lightband.
