SpatiumDDI is the open alternative to commercial DDI platforms that charge by the IP, by the appliance, and by the feature, then lock every zone and subnet you own inside a renewal cycle. It does not just render configuration for servers somebody else runs, but deploys and operates BIND9, PowerDNS, Technitium, and Kea itself. Manage zones and records with per-server sync state, hand out DHCP scopes, pools, and static reservations per server group, and watch live leases reported back by the Kea agents. The IPAM side keeps spaces, blocks, and subnets in a tree with per-address DNS and DHCP sync, while the dashboard shows utilization, capacity, and platform health at a glance. Bring an existing estate with you through importers for BIND, Windows, PowerDNS, Technitium, Kea, ISC, and NetBox, and manage Windows DNS and DHCP agentlessly over WinRM when a full cutover is not on the table. Delegate safely with group-based roles over LDAP, OIDC, SAML, RADIUS, or TACACS+, search every object globally, and keep an append-only audit log of who changed what.
