1. DNS/DHCP REFRESH June, 2013

2. Executive Summary The Domain Name System (DNS) and Dynamic Host Protocol (DHCP) are the lifeblood of the network. Without reliable DNS and DHCP, critical applications including e-mail, web-services and VoIP cannot function. DNS/DHCP services allow servers to communicate thru domain names and hands out dynamic IP addresses to workstations and other devices connecting to the network Currently our DNS/DHCP services are end of software/hardware support and require replacement for this function to remain supportable. The existing servers have 97 level four and five vulnerabilities and can’t be fixed because of the hardware that they are hosted on are end of support. The software/hardware are no longer upgradable. The scope covers the DNS/DHCP servers at the below locations: – Chandler DNS/DHCP Servers – El Segundo DNS/DHCP Servers – London DNS/DHCP Servers It is possible that an extended complete outage could occur if we have a major failure and cannot receive support. 2
