# Manage IP addresses

# Manage IP addresses {#ariaid-title1}

Release version: Australia  
Updated September 10, 2026

Manage IP address allocation in the application by creating IP Address Blocks, IP Subnetworks, allocated IP addresses, and IP Address records. These addresses are expressed in Classless Inter-Domain Routing (CIDR) notation.
Both IPv4 and IPv6 are supported.

IP address management involves creating top-level IP Address Blocks and subdividing them into IP Subnetworks with optional nesting. Follow the procedures in this section to allocate IP address slots and create IP Address records.
* **[Create an IP Address Block record](https://servicenow-prod.fluidtopics.net/S7~AWj2an5aZ90dtgd~GTw)**   
  Create an IP Address Block record to define a top-level IP address range, expressed in Classless Inter-Domain Routing (CIDR) notation. The block becomes the parent for one or more IP Subnetworks. Supports both IPv4 and IPv6.
* **[Create an IP Subnetwork record](https://servicenow-prod.fluidtopics.net/9uvIJPRcTs8lUhUZ167X8A)**   
  Create an IP Subnetwork record to subdivide an IP Address Block or to nest a subnetwork within an existing IP Subnetwork. The subnetwork's CIDR must fall within its parent's range. This task supports both IPv4 and IPv6.
* **[Allocate IP address slots in a subnetwork](https://servicenow-prod.fluidtopics.net/GNz3ONnBMKadJjPBuzh8ZQ)**   
  Allocate IP address slots to create one Allocated IP Address record for each address in a subnetwork CIDR. Reserved addresses (the first and last for IPv4, or the first for IPv6) are flagged automatically and can't be promoted to IP Address records.
* **[Create an IP Address record from allocated IPs](https://servicenow-prod.fluidtopics.net/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://servicenow-prod.fluidtopics.net/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.
* **[Create a managed network](https://servicenow-prod.fluidtopics.net/GiLKdONZ7fROMMC_C69oeA)**   
  Create a Managed Network record to define a network scope that can be assigned to IP Address Blocks. A Managed Network value propagates to subnetworks and allocated IP records beneath the IP Address Block, and the same CIDR can exist in different Managed Networks without conflict.
