Lattice DDI is software-only DDI for operators who are done with Windows DHCP plus a spreadsheet of used IPs — and do not want an appliance quote as the only alternative. IPAM and DHCP are one catalog. The reservation you save is the next Offer. Helpdesk pastes a MAC and lands on the lease. Discover on one node and Ack on another is the same pool. Names follow the lease into the DNS you already run (AD, BIND, or PowerDNS). You keep Option 6 on the resolver you trust. We sell a tarball and a signed entitlement you run on Ubuntu — not hardware, not a required phone-home, not a Grid replica of your leases. Community signup issues a signed entitlement so you can try it. LatticeDDI, LLC. Missouri / remote. Start at latticeddi.com.
