# create

Reserve a block of static public IPv4 addresses

## Usage

```
ionosctl compute ipblock create [flags]
```

## Aliases

For `ipblock` command:

```
[ip ipb]
```

For `create` command:

```
[c]
```

## Description

Reserve an IpBlock: a set of `--size` static, public IPv4 addresses held in one `--location` (region). The reserved IPs can then be assigned to NICs, NAT gateways, load balancers or IP-failover groups in any Virtual Data Center in that SAME location.

Both --location and --size are fixed at reservation time and cannot be changed later - a block cannot be moved to another region or resized. Reserved IPs are billed while held and persist across server power-offs (unlike dynamic DHCP addresses), so reserve only what you need.

Reservation is asynchronous. Use `--wait` (`-w`) to block until the IpBlock reaches AVAILABLE state and its IPs are ready to assign.

## Options

```
  -u, --api-url string    Override default host URL. Preferred over the config file override 'cloud' and env var 'IONOS_API_URL' (default "https://api.ionos.com")
      --cols strings      Set of columns to be printed on output 
                          Available columns: [IpBlockId Name Location Size Ips State]
  -c, --config string     Configuration file used for authentication (default "$XDG_CONFIG_HOME/ionosctl/config.yaml")
  -D, --depth int         Level of detail for response objects (default 1)
  -F, --filters strings   Limit results to results containing the specified filter:KEY1=VALUE1,KEY2=VALUE2
  -f, --force             Force command to execute without user input
  -h, --help              Print usage
      --limit int         Maximum number of items to return per request (default 50)
  -l, --location string   Region the IPs are reserved in, as <country>/<city> (e.g. de/txl Berlin, de/fra Frankfurt, us/las Las Vegas). The block can only serve resources in this region and cannot be moved afterwards. Location de/fra/2 is currently unavailable (default "de/txl")
  -n, --name string       A friendly label for the block (shown in listings; not the IP addresses themselves). If omitted, the API assigns a name automatically
      --no-headers        Don't print table headers when table output is used
      --offset int        Number of items to skip before starting to collect the results
      --order-by string   Property to order the results by
  -o, --output string     Desired output format [text|json|api-json] (default "text")
      --query string      JMESPath query string to filter the output
  -q, --quiet             Quiet output
      --size int          How many static public IPv4 addresses to reserve in this block. Fixed at creation - a block cannot be resized later. Each reserved IP is billed while held (default 2)
  -t, --timeout int       Timeout in seconds for --wait and other wait operations (default 600)
  -v, --verbose count     Increase verbosity level [-v, -vv, -vvv]
  -w, --wait              Wait for the resource to reach AVAILABLE state after the command completes. No-op for list commands
```

## Examples

```
# Reserve a block of 1 IP in Berlin (de/txl)
ionosctl compute ipblock create --name web-vip --location de/txl --size 1 --wait

# Reserve 4 IPs in Frankfurt for a load balancer / failover pool, then list the assigned addresses
ionosctl compute ipblock create --name lb-pool --location de/fra --size 4 --wait
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ionos.com/cloud/tools-cli/subcommands/compute-engine/ipblock/create.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
