# CMDB relationships for IP address records

# CMDB relationships for IP address records {#ariaid-title1}

Release version: Australia  
Updated November 5, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
When an IP Address record is created, the system writes one or two relationship records to the CMDB relationship table (cmdb_rel_ci). The relationships created depend on which allocation method was used to create the IP Address
record. The relationships are visible on the IP Address record's Related Items panel and in the Dependency View.

## Relationships created by each allocation method {#cmdb-relationships-for-ip-address-records__relationships-by-method}

From
allocated IPs, when an IP Address record is created from a selected allocated IP, the system writes two relationships:
{#cmdb-relationships-for-ip-address-records__from-allocated-ips-relationships__entry__3}

| Relationship type | Parent | Child |
|-|-|-|
| Managed by :: Manages | Allocated IP Address record | IP Address record |
| Contains :: Contained by | IP Subnetwork record | IP Address record |
[Table 1. Relationships created from allocated IPs]

{#cmdb-relationships-for-ip-address-records__from-allocated-ips-relationships}

The Manages relationship links the new IP Address record to the allocated IP slot it was created from. The Contains relationship links the IP Address record to the subnetwork it belongs to.

At subnet level (subnetwork-as-a-CI method), when a single IP Address record is created for the subnetwork as a whole, the system writes one relationship:
{#cmdb-relationships-for-ip-address-records__at-subnet-level-relationships__entry__3}

| Relationship type | Parent | Child |
|-|-|-|
| Contains :: Contained by | IP Subnetwork record | IP Address record |
[Table 2. Relationships created at subnet level]

{#cmdb-relationships-for-ip-address-records__at-subnet-level-relationships}

No Manages relationship is created because the IP Address record is not linked to any specific allocated IP slot.

## Effect of deletion {#cmdb-relationships-for-ip-address-records__effect-of-deletion}

When an IP Address record is deleted, the relationships it participated in are also removed:

* For records created from allocated IPs, the deletion removes both the Manages relationship and the Contains relationship. The allocated IP slot's Is Managed field is set to False automatically. The slot itself is preserved and remains available for reuse.
* For records created at subnet level, the deletion removes the Contains relationship.

## Where relationships appear in the workspace {#cmdb-relationships-for-ip-address-records__where-relationships-appear}

* Related Items panel: Each IP Address record displays its parent records under Related Items on the record's detail page.
* Dependency View: From the IP Address record's three-dot menu, select Dependency View. The view shows the IP Address record and its parent records as nodes connected by their relationship types.

The data model supports both IPv4 and IPv6, and supports nesting subnetworks to any depth within a parent.")

* [Create an IP Address record from allocated IPs](https://www.servicenow.com/docs/hRNDS4NQVx0~F9JurffE9g "Create one or more IP Address records by selecting allocated IP slots and promoting them to active CMDB Configuration Items.")
* [Create an IP Address record at subnet level](https://www.servicenow.com/docs/q3YlFrpcnUl5o5EeYJXmVA "Create a single IP Address record that represents an entire IP Subnetwork as one Configuration Item. The IP Address record uses the subnetwork'ss CIDR as its value, rather than a single host address. This method is used when the subnetwork is bound to a service, port, customer, or interface as a single entity.")
