IPAM

Use IPAM (IP Address Management) to audit IP addresses, VLANs, and DHCP scopes across your environment.

IPAM helps with:

  • Address-capacity planning

  • Assignment and ownership audit

  • VLAN/subnet consistency checks

  • DNS and DHCP alignment validation

Term Definitions:

  • IPAM: IP Address Management, inventory and lifecycle tracking of IP resources.

  • Prefix: subnet in CIDR form (for example 192.168.10.0/24).

  • VRF: Virtual Routing and Forwarding instance that isolates routing tables.

  • Gateway: default next hop for traffic leaving a subnet.

Step: Open IPAM

When to Use: Use this for IP, VLAN, and DHCP capacity and assignment audits.

Purpose: Open IPAM to baseline address inventory, segmentation, and scope utilization.

IPAM dashboard default view

Dashboard shows:

  • Summary cards for total counts and role-based filters.

  • Four operational tabs: IP Addresses, VLANs, DHCP Scopes, and Public IPs.

  • Addressing inventory and utilization context across the environment.

What you can do from this screen:

  • Audit address ownership and availability.

  • Validate VLAN/subnet/gateway consistency.

  • Check DHCP scope utilization before deployment.

Steps:

  1. Open Control Center -> Network -> IPAM.

  2. Review the top summary cards.

  3. Switch between IP Addresses, VLANs, DHCP Scopes, and Public IPs tabs.

Expected Outcome:

  • You can baseline addressing health, segmentation, and DHCP utilization from one page.

If this fails:

  1. Reopen IPAM and return to IP Addresses before retrying tab navigation.

  2. Confirm your account can access IPAM.

  3. Confirm IPAM data sources are available in your environment.

Step: Open IPAM Help Panel

When to Use: Use this after opening IPAM when you need field and role definitions.

Purpose: Open page help separately from dashboard review.

Steps:

  1. Open Control Center -> Network -> IPAM.

  2. Click the top-right help icon.

  3. Review and search the help panel content.

IPAM help panel

Expected Outcome:

  • IPAM help opens in the right-side panel.

  • You can continue tab-level operations with clearer context.

If this fails:

  1. Refresh the page and click the help icon again.

  2. Confirm your account can access in-product help content.

  3. Retry after reopening IPAM.

Tabs Overview

When to Use:

Use this before analysis when deciding which IPAM tab matches your goal.

Purpose:

Select the correct tab first so you review the right dataset.

Steps:

  1. Open Control Center -> Network -> IPAM.

  2. Review available tabs: IP Addresses, VLANs, DHCP Scopes, Public IPs.

  3. Select the tab that matches your current task.

Expected Outcome:

  • You select the correct tab before filtering or troubleshooting.

If this fails:

  1. Refresh IPAM and confirm tabs render correctly.

  2. Confirm your account can access all IPAM tabs.

  3. Reopen IPAM and retry tab selection.

Tab

What It Shows

IP Addresses

IP records with status, role, device, VLAN, VRF, and gateway.

VLANs

VLAN segments with role, prefix, gateway, DNS zone, and linked DHCP scope.

DHCP Scopes

DHCP subnets with role, VLAN, gateway, and utilization.

Public IPs

Public-IP inventory across the pool, with allocation and role context.

Stats Cards (Summary Bar)

When to Use:

Use this to get a quick role-based snapshot before drilling into table rows.

Purpose:

Use card counts and role filters to narrow data quickly.

Steps:

  1. Open Control Center -> Network -> IPAM.

  2. Stay on the target tab (IP Addresses, VLANs, or DHCP Scopes).

  3. Click TOTAL to show all rows.

  4. Click a role card (BMC, MANAGEMENT, PUBLIC, STORAGE, GUEST) to filter.

  5. Click the same role again or TOTAL to clear filter.

Expected Outcome:

  • Card counts provide immediate distribution context.

  • Table rows are filtered to the selected role.

If this fails:

  1. Clear filters with TOTAL and retry.

  2. Refresh the page and reapply the role filter.

  3. Confirm role-tagged data exists for the current tab.

At the top of each tab, cards show counts and provide role-based filters. The cards are labelled in capitals (TOTAL, BMC, MANAGEMENT); the table column headers below them are not - they read as IP / Prefix, DNS Zone, and so on.

TOTAL card:

  • Meaning: total row count for the current tab.

  • Click action: clears role filtering (shows all rows).

Role cards (BMC, MANAGEMENT, PUBLIC, STORAGE, GUEST):

  • Meaning: item count for that role category.

  • Click action: filter current tab to selected role.

  • Click the same role again or click TOTAL to clear filter.

Role guidance:

  • BMC: out-of-band management addressing.

  • MANAGEMENT: control-plane and host-management addressing.

  • PUBLIC: external/public addressing.

  • STORAGE: storage-network addressing.

  • GUEST: workload/tenant network addressing.

IP Addresses Tab

When to Use

Use this when auditing IP ownership, allocation state, and subnet context.

Purpose

Review IP-level records to identify active, reserved, released, and DHCP-tracked addresses.

Steps

  1. Open Control Center -> Network -> IPAM.

  2. Click IP Addresses.

  3. Optional: apply role filter cards.

  4. Review key columns: IP / Prefix, Status, Role, Device, VLAN, VRF, Gateway.

  5. Open row details for deeper assignment context when needed.

Expected Outcome

  • You can confirm IP assignment, state, and routing context for affected records.

If this fails

  1. Clear role filters by clicking TOTAL.

  2. Verify the expected subnet exists in VLANs.

  3. Refresh and reopen IP Addresses.

Each row represents one IP address record and its network context.

Table columns:

Column

Meaning

IP / Prefix

IP address and associated CIDR subnet.

Status

Active, Reserved, Deprecated (a released address), or Dhcp (an address the platform tracks against a DHCP lease). There is no Available status - a free address simply has no record and does not appear in this table.

Role

Traffic/purpose role of the IP.

Device

Assigned host/device and interface context when allocated.

VLAN

VLAN segment identifier and name.

VRF

Routing-instance context recorded in IPAM for this address. This is IPAM bookkeeping; it does not, on its own, imply a separate routing table on the fabric.

Gateway

Default gateway for the subnet.

How to use:

  • Audit how much of each prefix is already recorded as active or reserved.

  • Filter by role cards for targeted views.

  • Open row details for full assignment context.

VLANs Tab

When to Use

Use this when validating VLAN segmentation, subnet mapping, and DNS/DHCP linkage.

Purpose

Review VLAN-level design and ensure prefix, gateway, and service mappings are consistent.

Steps

  1. Open Control Center -> Network -> IPAM.

  2. Click VLANs.

  3. Optional: apply role filter cards.

  4. Review VID / Name, Status, Role, Prefix, Gateway, DNS Zone, and DHCP Scope.

Expected Outcome

  • You can verify VLAN segmentation and associated L3/service mappings.

If this fails

  1. Clear role filters with TOTAL.

  2. Confirm VLAN inventory is available for the current environment.

  3. Refresh and reopen VLANs.

Each row represents one VLAN segment and its L3/DNS/DHCP associations.

When to Use

Use this before provisioning workloads to check scope utilization and exhaustion risk.

Purpose

Review DHCP capacity and subnet consistency for reliable IP assignment.

Steps

  1. Open Control Center -> Network -> IPAM.

  2. Click DHCP Scopes.

  3. Optional: apply role filter cards.

  4. Review Prefix, Status, Role, VLAN, Gateway, and Utilization.

Expected Outcome

  • You can identify scopes approaching exhaustion and plan expansion before deployments fail.

If this fails

  1. Clear role filters with TOTAL.

Public IPs Tab

When to Use

Use this for a cluster-wide view of the public IP pool - across every VPC and guest network, not scoped to one VPC.

Purpose

Audit how much of the public prefix is free vs allocated, and acquire a fresh public IP without opening a specific VPC.

Steps

  1. Open Control Center -> Network -> IPAM.

  2. Click Public IPs.

IPAM Public IPs tab showing the public IP pool and allocated IP table

The Public IP pool card lists each public prefix with Prefix, Free IPs, VLAN, Status, Description, and an Acquire action. Acquire is disabled on an exhausted prefix (Prefix is exhausted - no free IPs) and for accounts without the network-management permission. Below the card, TOTAL/ALLOCATED/FREE cards summarise usage, and the Public IPs table lists every IP with its Public IP, Role, VPC, Network, and bound Instance.

Role is one of:

  • Free - no source NAT, static NAT, port-forwarding, or load-balancer rule on this IP yet. This covers both unallocated pool addresses and acquired addresses you have not built a rule on.

  • Source nat - the VPC’s egress IP.

  • Static nat - statically mapped to one instance.

  • Has rules - carries port-forwarding or load-balancer rules.

Note

The Source nat IP is platform-managed. It cannot take port-forwarding, firewall, or load-balancer rules - acquire a separate public IP for those. An IP with Static NAT enabled also refuses those rules until Static NAT is disabled.

Acquire a Public IP

  1. Click Acquire on the target prefix row. The Acquire Public IP dialog opens.

  2. Choose a target type. The two options are mutually exclusive - you pick one, and only that one’s picker appears:

    • VPC - the IP attaches to the VPC’s router. There is no tier or network field: the IP is not pinned to a tier until you add the first rule (port forwarding, static NAT, or load balancer) against a VM on that tier.

    • Guest network (isolated) - the IP attaches directly to one standalone guest network. Only non-VPC Isolated networks whose offering provides Source NAT or Static NAT are offered here. Shared networks, L2 networks, and VPC tiers never appear in this list - a VPC tier gets its public IP through the VPC instead.

  3. Pick the specific VPC or guest network.

  4. Finish:

    • For a VPC, click Continue, then confirm with Acquire. The confirmation has no input fields. When it completes it shows the allocated address; click Done.

    • For a guest network, click Acquire. Karios opens the new IP’s detail page on its Static NAT tab.

Acquire Public IP dialog showing the Target type picker set to VPC

Click a row to open the IP’s detail page, which carries Static NAT, Port Forwarding, Firewall, Load balancing, and VPN tabs. See Public IPs under VPCs for the rule workflows.

If this fails

  1. Confirm the zone’s public prefix has free capacity.

  2. Confirm your account has permission to acquire public IPs.

  3. Refresh and reopen Public IPs.

Tips

  • Start with TOTAL first, then apply role cards to avoid false conclusions from filtered views.

  • Review DHCP Scopes utilization before adding new VM batches.

  • Use IP Addresses tab when validating host/VM assignment issues.

Warnings

  • DHCP scope utilization near exhaustion can block new VM IP allocation.

  • Inconsistent VLAN/Prefix/Gateway values across tabs can indicate configuration drift.

Troubleshooting

  • Empty table unexpectedly: clear role filter by clicking TOTAL and verify no search filter is active.

  • Expected IP missing: check the correct role card and confirm the subnet exists in VLANs.

  • Scope running out of addresses: expand the subnet scope or add a new scope before provisioning more workloads.
