Specifications include, but are not limited to: 1. IPv4/IPv6 address management a. Ability to distinguish between authoritative (PTR) use and 3rd party IP addresses. Current vendor groups them all together. b. Ability to periodically validate address use. (reconciliation) c. VRF and VLAN tracking d. No limitations on CIDR size (supports /30, /31, /32 for IPv4, /127 /128 for IPv6, among others) e. ARP table and MAC address tracking (based on periodic polling) f. Facility for “find next 8 /24 subnets”, or similar ability. g. Integrated with authoritative DNS so PTR/A records are kept in sync. 2. Mixed vendor DNS management a. Internal authoritative zones are on MS AD DNS; External on vendor implemented BIND. b. Authoritative zones management on multiple hosted providers (Route53, Azure, NS1, …) c. Support for Route53 apex alias records is desired. d. CNAME creation to non-authoritative records (3rd party hosts). 3. DHCP management a.
