**IP-Lister solves these problems by providing centralized discovery, tracking, visualization, and automation for all IP assets.** — ### Core Features #### Automated Discovery and Inventory IP-Lister actively scans your network to discover devices and record their IP addresses, MAC addresses, hostnames, vendor information, and basic service fingerprints. It supports multiple discovery methods: – Ping and ICMP sweeps – ARP table parsing – SNMP queries for device metadata – DHCP server integration to import leases – Cloud API connectors (AWS, Azure, GCP) to pull instance network data #### IPv4 and IPv6 Support IP-Lister fully supports both IPv4 and IPv6 address spaces with tools to visualize subnets, allocate address blocks, and convert between CIDR notations. IPv6 SLAAC and DHCPv6 entries are tracked alongside IPv4 records. #### Centralized Database and Change History All discovered and manually entered IP records are stored in a central database with full versioning. Every assignment, reallocation, or annotation is logged with timestamps and user IDs so audits are simple and transparent. #### Subnet Management and Allocation Policies Create hierarchical subnet structures, define allocation pools, reserve ranges for special purposes, and apply policies (e.g., DHCP-only, static-only). IP-Lister can suggest optimal allocations to minimize fragmentation. #### DNS and DHCP Integration Bidirectional synchronization with DHCP and DNS systems ensures consistency: – Update DNS records when IP assignments change. – Reflect DHCP lease expirations and new leases in the IP inventory. – Integrate with Microsoft DHCP/DNS, ISC DHCP, BIND, and popular enterprise DNS/DHCP services. #### Role-Based Access Control (RBAC) Granular RBAC allows administrators to define who can view, edit, or allocate IPs. Approval workflows can be enforced for changes in critical subnets. #### Reporting and Analytics Pre-built and customizable reports provide: – Address utilization heatmaps – Aging and churn analysis – Allocation efficiency metrics – Compliance and audit-ready export (CSV, JSON, PDF) #### Alerts and Automation Set thresholds and alerts for low utilization, approaching exhaustion, or unauthorized IP changes. Automation hooks let you trigger scripts, webhooks, or ticketing workflows (Jira, ServiceNow) when specific events occur. #### REST API and Integrations A comprehensive REST API enables integration with provisioning systems, orchestration tools (Ansible, Terraform), and orchestration pipelines, allowing IP-Lister to be the single source of truth for IP allocations. — ### Typical Use Cases – Small IT teams replacing spreadsheets with a searchable, auditable IP inventory. – MSPs managing dozens of client networks with multi-tenant views and isolation. – Enterprises needing scale across multiple regions, clouds, and data centers. – Security teams detecting rogue devices and investigating incidents with historic IP usage. — ### Deployment Models IP-Lister supports flexible deployment options: – On-premises appliance for air-gapped environments. – Self-hosted cloud deployment using Docker/Kubernetes. – SaaS offering for minimal operational overhead. High-availability configurations, database replication, and backup utilities ensure enterprise SLAs are met. — ### Security and Compliance Security is integral: encrypted data at rest and in transit, audit logs, and integration with SSO providers (SAML, LDAP, OAuth) provide strong access controls. IP-Lister supports compliance requirements by producing tamper-evident audit trails and exporting reports required for audits. — ### Benefits — A Quick Summary – Reduce downtime caused by IP conflicts. – Eliminate manual spreadsheets and reduce human error. – Improve capacity planning and delay costly address renumbering projects. – Faster incident response with historical IP data. – Integrate IP management into infrastructure-as-code and automation workflows. — ### Example Workflow 1. Connect IP-Lister to your DHCP and DNS servers and cloud provider APIs. 2. Run an initial discovery to inventory the existing IP space. 3. Import legacy spreadsheets and consolidate records. 4. Define subnet hierarchies and allocation policies. 5. Use RBAC to delegate routine allocations to junior admins while requiring approvals for critical changes. 6. Monitor utilization dashboards and set alerts for low capacity or unusual activity. — ### Comparison with Other Tools | Capability | IP-Lister | Basic Spreadsheets | Generic CMDB | Enterprise IPAM | |—|—:|—:|—:|—:| | Automated discovery | Yes | No | Limited | Yes | | IPv6-first support | Yes | No | Limited | Yes | | DHCP/DNS sync | Yes | No | Partial | Yes | | REST API | Yes | No | Partial | Yes | | Role-based access | Yes | No | Partial | Yes | | Multi-tenant | Yes | No | Limited | Yes | — ### Getting Started – Trial the SaaS version or deploy a Docker image for evaluation. – Run discovery on a small subnet first to validate settings. – Migrate records gradually and keep legacy spreadsheets for cross-checking during transition. – Connect automation tools once the data is consistent. — IP-Lister is built to be the single source of truth for IP addresses in modern, hybrid networks. By combining automated discovery, strong integrations, policy-based allocation, and enterprise-grade security, it reduces risk, improves efficiency, and scales with your infrastructure.
