Here are the top IPAM (IP Address Management) solutions commonly chosen by enterprises, with a brief note on strengths and when to consider each. (Sources linked after each vendor.)

1. Infoblox (DDI: DNS, DHCP, IPAM)

   • Strengths: market-leading enterprise-grade DDI, authoritative single source of truth, strong automation and hybrid/multi‑cloud support, advanced security/integration features for large distributed networks. (Infoblox.com)

2. BlueCat (Micetro / BlueCat DDI)

   • Strengths: enterprise DDI with strong API-first automation, multi‑tenant/RBAC support, good integration with Cisco/VMware ecosystems; BlueCat acquired Men&Mice (Micetro) to broaden offerings. Good when you need overlay/automation and AD/SSO integration. (bluecatnetworks.com)

3. EfficientIP (SOLIDserver DDI)

   • Strengths: policy-driven DDI appliances, multi-cloud discovery/synchronization, focus on operational efficiency and DDI reliability for enterprises. Good fit for organizations wanting appliance/virtualized DDI with strong cloud connectors. (EfficientIP.com)

4. Men&Mice (Micetro — overlay DDI)

   • Strengths: lightweight overlay/orchestration for existing DNS/DHCP/IPAM services (on-prem + cloud), strong API and Microsoft environment support; note: Men&Mice was acquired by BlueCat (see above). Use when you need to orchestrate heterogeneous DDI without ripping and replacing. (menandmice.com)

5. SolarWinds IP Address Manager (IPAM)

   • Strengths: tightly integrated with SolarWinds Orion platform (NPM etc.), easy discovery and reporting, widely used in medium→large orgs that already use SolarWinds. Often chosen for practical, lower‑cost IPAM tied to monitoring. (try.SolarWinds.com)

6. Microsoft IPAM (built into Windows Server)

   • Strengths: native Windows Server feature providing address space management, DHCP/DNS auditing and RBAC; attractive for Microsoft‑centric shops that want an integrated, no‑additional‑vendor option. Best when your environment is heavily Active Directory / Microsoft Server based. (learn.Microsoft.com)

Other enterprise/near‑enterprise options to consider (smaller footprint / open-source / niche):

• phpIPAM (open source) — good for small teams or as adjunct, but less enterprise feature depth.
• Commercial niche vendors and DDI integrators (varies by region and ecosystem).

Quick selection guide (which to pick)

• Need highest-scale, mature DDI with security controls and enterprise support → Infoblox. (Infoblox.com)
• Need overlay/orchestration across existing heterogeneous DDI + strong API → BlueCat / Men&Mice. (bluecatnetworks.com)
• Want appliance/virtual DDI with cloud connectors and policy-driven controls → EfficientIP SOLIDserver. (EfficientIP.com)
• Already invested in SolarWinds monitoring and want integrated IPAM → SolarWinds IPAM. (try.SolarWinds.com)
• Microsoft‑only environment and prefer built‑in tooling → Microsoft IPAM in Windows Server. (learn.Microsoft.com)

If you’d like, I can:

• create a one‑page vendor comparison matrix (features, pricing model, scale, best fit), or
• recommend 2–3 vendors to trial based on your environment (scale, cloud vs on‑prem mix, AD reliance, budget).
