ISP IP Address Management — IPAM

Reviewed by the NowaCRM ISP operations team Last updated: May 18, 2026

Quick answer

IP addresses are finite and expensive resources. Mismanaging them leads to address conflicts, wasted allocations, and compliance issues. NowaCRM provides IP Address Management (IPAM) with pool creation, automated allocation, subscriber assignment tracking, and utilization analytics — ensuring every IP is accounted for.

01

IPv4 & IPv6 Pool Management

Create and manage IP pools by subnet — /24, /23, /22 for IPv4 and /48, /56, /64 for IPv6. Assign pools to specific NAS devices or locations. Track available, allocated, and reserved addresses per pool. Pool utilization dashboards alert you when pools approach capacity.

02

Automated IP Allocation

When a subscriber connects via RADIUS, NowaCRM can allocate an IP from the designated pool. Static IP assignment for business subscribers is supported alongside dynamic allocation for residential. Allocation follows configured policies — sequential, random, or pool-specific rules.

03

Subscriber IP Assignment Tracking

Every IP assignment is linked to a subscriber profile. View current and historical IP assignments per subscriber. When troubleshooting, search by IP to find the assigned subscriber instantly. For CGNAT deployments, public IP + port block + timestamp resolves to a specific subscriber.

04

Subnet Planning & Visualization

Plan your network addressing with subnet visualization tools. See parent/child subnet relationships. Identify gaps and overlaps in allocation. Plan IPv6 deployment alongside existing IPv4 infrastructure. Export addressing plans for network documentation.

05

Utilization Monitoring & Alerts

Monitor IP pool utilization in real-time. Set threshold alerts — e.g., notify when a /24 pool reaches 85% utilization. Historical utilization trends help forecast when new address space is needed. Partner-wise allocation reports show distribution across your network.
