Infoblox Ddi

When to Use

• IPAM source-of-truth validation before assigning addresses
• DNS cutover and record verification during change windows
• DHCP scope exhaustion checks
• Reverse-DNS validation for network devices and services
• Reconciliation between NetBox/Nautobot intent and Infoblox reality

Workflow: DNS Change Validation

1. Query the target zone and existing records.
2. Check for conflicting A, AAAA, CNAME, and PTR records.
3. Confirm the target IP is allocated correctly in IPAM.
4. If the change is a write operation, require a ServiceNow CR first.
5. Verify forward and reverse records after implementation.

Workflow: DHCP Scope Investigation

1. Query the affected network or scope.
2. Review lease utilization and remaining free addresses.
3. Check reservations and exclusions for collisions.
4. Correlate the client or IP with Catalyst Center, ISE, or pyATS data if needed.

Integration with Other Skills

Important Rules

• Do not modify DNS/DHCP/IPAM without approved change control
• Always verify both forward and reverse DNS after writes
• Treat DDI as production control-plane infrastructure
