Reference: https://docs.iot.telia.lt/developers/api/ip-address-spaces/ip-address-space-post ## Authentication - `Authorization` header (bearer token, required) — An `auth_token` should be provided to authenticate a session. To obtain an `auth_token`, see the [`/api/v1/authenticate` **POST** request](/developers/api/authentication/authenticate). ## Request ### Body (application/json) This endpoint expects an object. - `ip_address_space` (string, required) - `ip_address_version` (integer, required) ## Response ### 201 Created The requested IP address space is created. - `id` (integer, optional) - `ip_address_space` (string, optional) - `ip_address_version` (integer, optional) ## Errors ### 400 Bad Request Error Bad Request - `error_token` (string, required) - `message` (string, required) - `error_code` (integer, optional) - `errors` (list of ApiV1IpAddressSpacePostResponsesContentApplicationJsonSchemaErrorsItems, optional) — sub error descriptions ### 403 Forbidden Error Forbidden - `error_token` (string, required) - `message` (string, required) - `error_code` (integer, optional) - `errors` (list of ApiV1IpAddressSpacePostResponsesContentApplicationJsonSchemaErrorsItems, optional) — sub error descriptions ### 404 Not Found Error Not Found - `error_token` (string, required) - `message` (string, required) - `error_code` (integer, optional) - `errors` (list of ApiV1IpAddressSpacePostResponsesContentApplicationJsonSchemaErrorsItems, optional) — sub error descriptions ### 409 Conflict Error The requested IP address space overlaps with an existing allocated IP address space. For example, `10.176.0.0/12` and `10.176.0.0/24` or `10.188.33.16/28`. - `error_token` (string, required) - `message` (string, required) - `error_code` (integer, optional) - `errors` (list of ApiV1IpAddressSpacePostResponsesContentApplicationJsonSchemaErrorsItems, optional) — sub error descriptions ### 422 Unprocessable Entity Error Your requested IP address space isn't allowed or overlaps with a reserved range. These responses have different root causes but share an [error code](/developers/api-guidelines/errors#list-of-error-codes) and token. Be sure to check the error message to determine the exact cause. The requested IP address space must be in one of the following ranges: * `10.192.0.0/12` * `100.64.0.0/10` * `10.112.0.0/12` * `10.176.0.0/12` It also can't overlap with a reserved range (`100.64.0.0/24`). - `error_token` (string, required) - `message` (string, required) - `error_code` (integer, optional) - `errors` (list of ApiV1IpAddressSpacePostResponsesContentApplicationJsonSchemaErrorsItems, optional) — sub error descriptions ## Types ### ApiV1IpAddressSpacePostResponsesContentApplicationJsonSchemaErrorsItems ## Examples **Request** ```json { "ip_address_space": "10.199.128.0/18", "ip_address_version": 4 } ``` **Response** ```json { "id": 1234, "ip_address_space": "10.199.128.0/18", "ip_address_version": 4 } ``` **SDK Code** ```python Created import requests url = "https://iot.telia.lt/api/v1/ip_address_space" payload = { "ip_address_space": "10.199.128.0/18", "ip_address_version": 4 } headers = { "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript Created const url = 'https://iot.telia.lt/api/v1/ip_address_space'; const options = { method: 'POST', headers: {Authorization: 'Bearer ', 'Content-Type': 'application/json'}, body: '{"ip_address_space":"10.199.128.0/18","ip_address_version":4}' }; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```go Created package main import ( "fmt" "strings" "net/http" "io" ) func main() { url := "https://iot.telia.lt/api/v1/ip_address_space" payload := strings.NewReader("{\n \"ip_address_space\": \"10.199.128.0/18\",\n \"ip_address_version\": 4\n}") req, _ := http.NewRequest("POST", url, payload) req.Header.Add("Authorization", "Bearer ") req.Header.Add("Content-Type", "application/json") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby Created require 'uri' require 'net/http' url = URI("https://iot.telia.lt/api/v1/ip_address_space") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Post.new(url) request["Authorization"] = 'Bearer ' request["Content-Type"] = 'application/json' request.body = "{\n \"ip_address_space\": \"10.199.128.0/18\",\n \"ip_address_version\": 4\n}" response = http.request(request) puts response.read_body ``` ```java Created import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.post("https://iot.telia.lt/api/v1/ip_address_space") .header("Authorization", "Bearer ") .header("Content-Type", "application/json") .body("{\n \"ip_address_space\": \"10.199.128.0/18\",\n \"ip_address_version\": 4\n}") .asString(); ``` ```php Created request('POST', 'https://iot.telia.lt/api/v1/ip_address_space', [ 'body' => '{ "ip_address_space": "10.199.128.0/18", "ip_address_version": 4 }', 'headers' => [ 'Authorization' => 'Bearer ', 'Content-Type' => 'application/json', ], ]); echo $response->getBody(); ``` ```csharp Created using RestSharp; var client = new RestClient("https://iot.telia.lt/api/v1/ip_address_space"); var request = new RestRequest(Method.POST); request.AddHeader("Authorization", "Bearer "); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"ip_address_space\": \"10.199.128.0/18\",\n \"ip_address_version\": 4\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift Created import Foundation let headers = [ "Authorization": "Bearer ", "Content-Type": "application/json" ] let parameters = [ "ip_address_space": "10.199.128.0/18", "ip_address_version": 4 ] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://iot.telia.lt/api/v1/ip_address_space")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0) request.httpMethod = "POST" request.allHTTPHeaderFields = headers request.httpBody = postData as Data let session = URLSession.shared let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in if (error != nil) { print(error as Any) } else { let httpResponse = response as?
