Themelio · Unified DDI Platform

One platform for DNS, DHCP & IPAM.

Themelio is a modern, self-hosted DDI platform that brings DNS, DHCP and IP Address Management together in a single console — reliable, secure and owned by you. It runs entirely inside your own network: no cloud dependency, no call-home, perpetual licensing.

The basics

What is DDI?

DDI stands for DNS, DHCP and IPAM — the three core network services that assign and resolve every IP address on a network, managed together from one platform instead of three separate tools.

DNS

Domain Name System

Resolves human-readable names to IP addresses. A DDI platform manages authoritative and recursive zones, records, split-horizon views and DNSSEC signing from one console.

DHCP

Dynamic Host Configuration Protocol

Hands out IP addresses and network settings automatically as devices join. DDI covers IPv4 and IPv6 subnets, pools, reservations, client classes and live leases.

IPAM

IP Address Management

Plans and tracks the address space itself — a hierarchical inventory of every subnet and address, reconciled against what DNS and DHCP are actually serving.

The challenge

Fragmented DNS, DHCP & spreadsheets increase operational risk.

When core network services are managed in disconnected tools, routine changes become a leading cause of outages and audit gaps.

Without Themelio

  • DNS in one tool, DHCP in another, IPs tracked in a spreadsheet
  • Config drift and duplicate-IP conflicts
  • Outages with no audit trail to trace the change
  • Enterprise DDI suites priced well beyond actual requirements

With Themelio

  • One console — a single source of truth for every IP
  • Validate before apply, with automatic rollback
  • Full audit logging on every change
  • Perpetual license, on your own infrastructure
One platform, all-inclusive

Everything IT needs to run core network services.

A single platform for every core network service — without the cost and complexity of legacy DDI suites.

Unified

DNS, DHCP & IPAM in one console — every IP correlated with its record, lease and device.

Reliable

Validated changes, automatic rollback, DHCP HA, manager HA and encrypted backup / restore.

Secure

Role-based access, MFA and a complete audit trail — enforced at the API layer, on your infrastructure.

Efficient

Reservation workflows, discovery, REST API and infrastructure-as-code that fit your pipelines.

Scalable

Start with one appliance; grow to distributed DNS/DHCP nodes under one management grid.

AI assistant

Ask your network in plain language over an on-prem MCP server — read-only by default, every call audited.

DNS security

RPZ firewall, DGA & tunneling detection, encrypted DNS transport and offline threat-feed packs.

Query analytics

Top talkers, top domains and custom dashboards, with scheduled reports your auditor can read.

On-premise

Your data stays in-house. Air-gap friendly, no internet call-home — ever.

One management plane · many nodes

Deploys as one package. Scales as a grid.

Install a single, self-contained package — a standalone node for a site, or a managed grid across many sites and data centers. Each node joins the central Manager over a secure, outbound-only connection. No appliances, no cloud dependency, no internet required.

Active + standby management

Virtual IP and database replication keep the control plane available; automatic failover targets under 60 seconds.

Outbound-only, secure by design

Nodes connect to the Manager over mutual-TLS with no inbound management ports to expose.

Runs anywhere

Linux on VM or bare metal — VMware, Proxmox, Hyper-V — fully offline / air-gap capable.

From install to serving

Up and running in four steps — no appliances, no cloud.

Themelio deploys as a single software package and is managed entirely from one console. Bring nodes online, import your existing zones and scopes with a preview, then serve — with validation and automatic rollback on every change.

STEP 01

Deploy the platform

Install one self-contained package — a standalone node, or a managed grid — entirely inside your own network.

STEP 02

Bring nodes online

Each node joins the central Manager over a secure, outbound-only connection — no inbound ports to open.

STEP 03

Import & stage

Import DNS zones and DHCP scopes with a preview — including Microsoft DNS/DHCP sync — then stage changes safely.

STEP 04

Serve with validation

Deploy with validation and automatic rollback, then run the whole estate from one screen — auditable end to end.

Software, not hardware

No appliance to buy. No end-of-life clock. Scale in any shape.

Themelio is pure software — so your DDI is never trapped on a vendor appliance with a refresh deadline. Deploy on the platforms you already run, and grow by adding software nodes instead of forklift-replacing hardware.

Runs anywhere you do

VMware, Proxmox, Hyper-V, KVM, bare metal, private cloud and air-gapped sites — one package, no proprietary box to rack.

Scale any shape

Go vertical (a bigger VM) or horizontal (more DNS/DHCP nodes in one grid) — from a single standalone node at a branch to a highly available grid across many sites and data centers.

Evergreen — no EOS treadmill

No End-of-Sale / End-of-Support date forcing a hardware buy every few years. A perpetual license and in-place updates keep you current.

AI assistant · MCP
READ-ONLY · AUDITED
AI-native operations

Ask your network in plain language — safely.

Themelio ships a built-in MCP (Model Context Protocol) endpoint, so an AI assistant can read and reason over your live DNS, DHCP and IPAM — the real-time signal at the core of every network — without a human digging through consoles.

Natural-language answers

“Which subnets are nearly full?” “Where is this IP used?” — answered from your own source of truth, in seconds.

Read-only by default, every call audited

The AI can look, not touch. Scoped API keys, RBAC and a full audit trail apply to the assistant just like any user.

On-prem, no data exfiltration

The MCP server runs inside your perimeter over standard JSON-RPC 2.0 — your DDI data never leaves your network.

Performance & sizing · standalone (benchmarked)

Pick a tier by peak query and lease rates.

Measured results from sustained load testing of a single standalone node running DNS, DHCP, IPAM and management together. Scale beyond one node with dedicated DNS/DHCP nodes in a Standard or Enterprise grid.

Small 4 · 8 GB 30,000 QPS 500 leases/s Branch / small campus
Medium 8 · 16 GB 65,000 QPS 750 leases/s Campus / department
Large 16 · 32 GB 100,000 QPS 1,000 leases/s Data center / core site

// Figures are benchmarked single-node results on the stated VM profile (10 GbE NIC on Large). Log storage is provisioned separately to retention. Deploy dedicated DNS/DHCP nodes to scale further.
