A public IP pool is simply a set of IPv4 CIDR blocks allocated to a tenancy. These CIDR
blocks can be all or part of a BYOIP CIDR block. Public
IP CIDR blocks assigned to a pool are only available for your tenancy. Public IP pools
are available as a source for IP allocation when launching a NAT gateway, load balancer,
or compute instance. You can add more IP CIDR blocks to a public IP pool at any time.
You can also:
Create a Reserved IP: You can reserve individual IPs from your public IP
pools. These reserved IP addresses can be attached to your resources.
Direct launch from pool: You can launch resources with an IP directly
allocated from a public IP pool without previously creating a reserved IP for that
resource.
Delete CIDR blocks and pools: You can delete the entire public IP pool or
certain IP CIDR blocks within the pool, provided none of the IP addresses are
currently attached or reserved.
Note
IPv6 addresses do not use the IP Pools functionality described here. Instead, you can
directly assign IPv6 prefixes to VCNs and subnets.
Requirements and Preparation
To use public IP pools with BYOIP addresses, you
need to import your addresses.
To reserve Oracle-supplied public IP addresses, select "Oracle" as the public IP
pool when creating the reserved public IP address.
Limits and quotas 🔗
You can create one or up to 10 public IP pools in a compartment.
A public IP pool can have zero or more IP CIDR ranges assigned to it, with a
minimum size of /28 to a maximum size of /24.
To use Oracle Cloud Infrastructure, an administrator must be a member of a group granted security access in a policy by a tenancy administrator. This access is required whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you get a message that you don't have permission or are unauthorized, verify with the tenancy administrator what type of access you have and which compartment your access works in.

Open the navigation menu and select Networking. Under IP management, select Public IP pools.
Select a public IP pool from the list and click Delete Public IP Pool.
If there are no warnings or errors, click Delete Public IP Pool. If this
public IP pool contains reserved public IP addresses currently in use, you can't
delete the public IP pool.
To successfully remove a BYOIP CIDR block from a
public IP pool, there must be no reserved public IP addresses from that address range.
You may have to terminate one or more reserved public IP addresses.
Confirm you're viewing the region and compartment you're interested in.
