Tidal LightMesh IPAM helps organizations establish a reliable, centralized source of truth for network address space across cloud, hybrid, and on-premises infrastructure. Built for enterprise scale, LightMesh can support millions of IPs, thousands of locations, hundreds of users, and complex environments with overlapping network ranges. Network teams gain visual TreeView mapping, IPv4/IPv6 management, subnet planning, capacity monitoring, conflict detection, global search, custom fields, and bulk migration tools in one platform. Automated discovery reduces the effort required to maintain accurate IP records. LightMesh synchronizes Microsoft DHCP servers, scopes, leases, reservations, and lease history, while ICMP Ping Sweep discovery helps identify active hosts. Read-only AWS, Azure, and Cisco Meraki integrations provide additional visibility across distributed infrastructure, with Nmap supporting further network discovery. Enterprise organizations can standardize IPAM processes using SSO, role-based access controls, Requestor approval workflows, audit history, APIs, and support for multi-site and overlapping address spaces. API-driven automation also enables integration with DevOps, CI/CD, Terraform, Ansible, and security workflows. Available as SaaS or self-hosted, LightMesh provides the deployment flexibility, governance, and scalability needed to modernize IPAM and move away from spreadsheets or legacy platforms.
