IP Address Management
This playbook outlines the process for managing the allocation, classification, and tracking of IP addresses within large-scale networks to ensure organized and efficient network operation.
Step 1: Preparation
Gather all necessary documentation and tools required for IP address management. This includes access to the IPAM tool, network diagrams, and existing IP address allocations.
Step 2: Audit
Conduct an audit of current IP address usage across the network. Identify all allocated, reserved, and unused IP addresses.
Step 3: Classification
Classify IP addresses based on purpose, like dynamic allocation (DHCP), static allocation, infrastructure, virtual interfaces, and services.
Step 4: Allocation
Allocate new IP addresses based on classification needs and availability. Ensure that no IP addresses are duplicated and that they fit into the proper subnet architecture.
Step 5: Documentation
Document the allocation and classification of IP addresses in the IPAM tool or system. Include details such as device names, locations, and purpose.
Step 6: Monitoring
Set up monitoring systems to track the usage and status of IP addresses. Use this data to identify trends and anticipate future needs.
Step 7: Review
Regularly review and update the IP address management records to reflect any changes in the network, such as new devices, decommissioned devices, or reconfigured networks.
Step 8: Policy Update
Update organizational policies and procedures to reflect any changes in IP address management practices and ensure compliance with current network standards.
General Notes
IPAM Software
Consider using dedicated IPAM software to automate many of the tasks associated with IP address management for efficiency and accuracy.
