For more information, see [Bring your own IP\nconfigurations](/vpc/docs/bring-your-own-ip#comparison).\n\nWe recommend that you use v2 public advertised prefixes to create regional\npublic delegated prefixes. You must use v2 public advertised prefixes to import\nIPv6 prefixes to Google Cloud.\n\nBefore you begin\n----------------\n\n- [Create a public advertised prefix](/vpc/docs/create-pap).\n- If you're creating a global public delegated prefix, the parent public advertised prefix must meet these requirements:\n - The public advertised prefix is used for global public delegated prefixes only.\n - The public advertised prefix is in a project that has been added to the allowlist for global prefixes. For more information, see [Global public\n delegated prefixes](/vpc/docs/bring-your-own-ip#global-pdp).\n\n### Roles\n\n\nTo get the permissions that\nyou need to complete the tasks in this guide,\n\nask your administrator to grant you the\n\n\n[Compute Public IP Admin](/iam/docs/roles-permissions/compute#compute.publicIpAdmin) (`roles/compute.publicIpAdmin`)\nIAM role on your project.\n\n\nFor more information about granting roles, see [Manage access to projects, folders, and organizations](/iam/docs/granting-changing-revoking-access).\n\n\nYou might also be able to get\nthe required permissions through [custom\nroles](/iam/docs/creating-custom-roles) or other [predefined\nroles](/iam/docs/roles-overview#predefined).\n\nCreate public delegated prefixes\n--------------------------------\n\n\nA public delegated prefix name can't be changed without deleting and recreating\nthe resource. For this reason, we recommend that you create generic names that\nwon't need to change---for example, `pdp-203-0-113-0-25`, where `pdp`\ndenotes the resource type and `203-0-113-0-25` denotes the specific prefix and\nprefix length.\n\nTo create a global public delegated prefix, you must use a public advertised\nprefix that is used for global public delegated prefixes only, and is in a\nproject that has been added to the allowlist for global prefixes. For more\ninformation, see [Global public delegated\nprefixes](/vpc/docs/bring-your-own-ip#global-pdp). \n\n### Console\n\n1. In the Google Cloud console, go to **Bring your own IP**.\n\n[Go to Bring your own IP](https://console.cloud.google.com/networking/byoip)\n\n1. Click the public advertised prefix that you want to delegate.\n2. Click **Create PDP**.\n3. For **Name**, enter a name for the public delegated prefix.\n4. For **Description**, enter an optional description for the public delegated prefix.\n5. If you're creating a public delegated prefix for an IPv4 address range, do the following:\n 1. Select a prefix length from the **Prefix length** list.\n 2. Select a range of IP addresses from the **IP addresses** list.\n 3. Select a **Scope** for the public delegated prefix.\n 4. If you selected **Regional** for the scope, select a **Region**.\n6. If you're creating a public delegated prefix for an IPv6 address range, do the following:\n 1. Select a prefix length from the **IPv6 prefix length** list.\n 2. Enter an IPv6 address range in **IPv6 range**.\n 3. Select a region from the **Region** list.\n7. Select a **Project** for the public delegated prefix.\n8. Click **Create**.\n\n### gcloud\n\nUse the [`public-delegated-prefixes\ncreate`\ncommand](/sdk/gcloud/reference/compute/public-delegated-prefixes/create).\n\n- To create an IPv4 PDP, use the following command:\n\n ```\n gcloud compute public-delegated-prefixes create PDP_NAME \\\n --public-advertised-prefix=PAP_NAME \\\n --range=PDP_IP_RANGE \\\n --region=PDP_REGION\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003ePDP_NAME\u003c/var\u003e: the name to use for the public delegated\n prefix that you are creating.\n\n - \u003cvar translate=\"no\"\u003ePAP_NAME\u003c/var\u003e: the name of the public advertised prefix to\n use to create the public delegated prefix.\n\n - \u003cvar translate=\"no\"\u003ePDP_IP_RANGE\u003c/var\u003e: the IPv4 or IPv6 address range to use\n to create the public delegated prefix.\n\n - \u003cvar translate=\"no\"\u003ePDP_DESCRIPTION\u003c/var\u003e: an optional description for the\n public delegated prefix.\n\n - \u003cvar translate=\"no\"\u003ePDP_REGION\u003c/var\u003e: the region where you want to use the\n public delegated prefix addresses. If you want a global public delegated\n prefix instead, replace `--region=`\u003cvar translate=\"no\"\u003ePDP_REGION\u003c/var\u003e with\n `--global`.\n\n- To create an IPv6 PDP, use the following commamd:\n\n ```\n gcloud compute public-delegated-prefixes create PDP_NAME \\\n --public-advertised-prefix=PAP_NAME \\\n --range=PDP_IP_RANGE \\\n --region=PDP_REGION \\\n --mode=DELEGATION\n ```\n\nCheck the status of a public delegated prefix\n---------------------------------------------\n\nYou can check the status of a public delegated prefix. The available statuses\nfor both v2 and v1 public delegated prefixes are described in the following\ntable.\n\n\n### Console\n\n1. In the Google Cloud console, go to **Bring your own IP**.\n\n [Go to Bring your own IP](https://console.cloud.google.com/networking/byoip)\n2. The **Status** column displays the status for all public delegated\n prefixes.\n\n### gcloud\n\nTo describe the public delegated prefix and get its status, use the\n[`public-delegated-prefixes describe`\ncommand](/sdk/gcloud/reference/compute/public-delegated-prefixes/describe). \n\n```\ngcloud compute public-delegated-prefixes describe PDP_NAME \\\n --region=PDP_REGION \\\n --format='value(status)'\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003ePDP_NAME\u003c/var\u003e: the public delegated prefix or sub-prefix\n that you want to get information for.\n\n- \u003cvar translate=\"no\"\u003ePDP_REGION\u003c/var\u003e: the region of the public delegated prefix\n or sub-prefix.\n\n- \u003cvar translate=\"no\"\u003ePDP_REGION\u003c/var\u003e: the region where you want to use the\n public delegated prefix addresses.
