--- title: "Delegate a zone (domain)" description: "How to delegate a domain to Selectel DNS hosting, how to delegate a domain and subdomain to different DNS hostings" sidebar_position: 2 --- import Formbricks from '@theme/MDXComponents/Formbricks'; import MoreVerticalIcon from '@selectel/docux/icons/more-vertical'; # Delegate a zone (domain) A domain zone is a collection of domain resource records. A domain zone is propagated from dedicated servers in the DNS system—NS servers—which are specified in the domain's NS records. When registering a domain, you specify the registrar's NS servers for it. To manage a domain zone via DNS hosting, you must delegate the domain—specify the hosting's NS servers with the registrar. If you [delegate the primary domain to Selectel](#delegate-domain-and-subdomains-to-Selectel), all its subdomains will be delegated to Selectel by default. You can manage the primary domain zone and subdomain zones via different hostings, for example: * [delegate the primary domain to a third-party hosting, and the subdomain to Selectel](#domain-elsewhere-subdomain-in-selectel); * [delegate the primary domain to Selectel, and the subdomain to a third-party hosting](#domain-in-selectel-subdomain-elsewhere). ## Delegate the primary domain and subdomains to Selectel \{#delegate-domain-and-subdomains-to-Selectel} 1. In the [Control panel](https://my.selectel.ru/dns/default/hosting), on the top menu, click **Products** and select **DNS hosting**. 2. Make sure you have [created a zone](/dns-hosting/zones/create-zone.mdx) for the primary domain and [added resource records to it](/dns-hosting/records/add-record.mdx). 3. To add resource records for a subdomain, [create a zone](/dns-hosting/zones/create-zone.mdx) for the subdomain and [add resource records to it](/dns-hosting/records/add-record.mdx). The main domain zone and the subdomain zone must be created in the same [project](/access-control/projects/about-projects.mdx). After creation, you will be able to [transfer the subdomain zone to another project](/dns-hosting/zones/transfer-zone.mdx#transfer-zone-to-another-project). 4. Go to the control panel of the domain registrar where your primary domain is registered. 5. In the NS records, replace the values with Selectel's NS servers: `a.ns.selectel.ru`, `b.ns.selectel.ru`, `c.ns.selectel.ru`, `d.ns.selectel.ru`. Each server must be specified in a separate record. When the zone status in the [Control panel](https://my.selectel.ru/dns/default/hosting) changes to `DELEGATED`, records will start being served from Selectel's servers. 6. Wait for the NS records to propagate to the DNS servers. Propagation can take up to 72 hours. ## Delegate the primary domain to a third-party hosting, and the subdomain to Selectel \{#domain-elsewhere-subdomain-in-selectel} 1. Go to the control panel of the domain registrar where your primary domain is registered. 2. Ensure that the NS servers of the third-party hosting are specified for the primary domain. 3. Create a subdomain zone in Selectel: 3.1. In the [Control panel](https://my.selectel.ru/dns/default/hosting), on the top menu, click **Products** and select **DNS hosting**. 3.2. Click **Add zone**. 3.3. Enter the subdomain name with a trailing dot, for example `first.example.com.`. 3.4. Click **Add**. NS and SOA records with default values will be automatically created in the subdomain zone: * NS — `a.ns.selectel.ru.`, `b.ns.selectel.ru.`, `c.ns.selectel.ru.`, `d.ns.selectel.ru`. * SOA — `a.ns.selectel.ru. support.selectel.ru.` ` 10800 3600 604800 60`, where `` is the zone serial number, which changes when the zone is updated and signals caching servers that the records need to be recached. 3.5. Optional: [transfer the subdomain zone to another project](/dns-hosting/zones/transfer-zone.mdx#transfer-zone-to-another-project). 4. Delegate the subdomain: 4.1. Go to the control panel of the third-party hosting to which the primary domain is delegated. 4.2. In the primary domain's zone, create four NS records, one for each of the Selectel NS servers: * record name — subdomain name, for example `first.example.com`; * record value — one of the authoritative Selectel servers: `a.ns.selectel.ru`, `b.ns.selectel.ru`, `c.ns.selectel.ru`, `d.ns.selectel.ru`. When the subdomain zone status in the [Control panel](https://my.selectel.ru/dns/default/hosting) changes to `DELEGATED`, records will start being served from Selectel's servers. 4.3. Wait for the NS records to propagate to the DNS servers. Propagation can take up to 72 hours. ## Delegate primary domain to Selectel, subdomain to a third-party hosting \{#domain-in-selectel-subdomain-elsewhere} 1. In the [Control panel](https://my.selectel.ru/dns/default/hosting), on the top menu, click **Products** and select **DNS hosting**. 2. Make sure you have [created a zone](/dns-hosting/zones/create-zone.mdx) for the primary domain and [added resource records to it](/dns-hosting/records/add-record.mdx). 3. Delegate the primary domain to Selectel: 3.1. Go to the control panel of the domain registrar where your primary domain is registered. 3.2. In the domain's NS records, replace the values with Selectel's NS servers: `a.ns.selectel.ru`, `b.ns.selectel.ru`, `c.ns.selectel.ru`, `d.ns.selectel.ru`. Specify each server in a separate record. When the zone status in the [Control panel](https://my.selectel.ru/dns/default/hosting) changes to `DELEGATED`, records will start being served from Selectel's servers. 4. Delegate the subdomain to a third-party hosting: 4.1. In the [Control panel](https://my.selectel.ru/dns/default/hosting), on the top menu, click **Products** and select **DNS hosting**. 4.2. Open the primary domain zone page. 4.3. Add a group of NS records; to do this, click **Add** and provide the details: * group name — subdomain name; * record type — NS; * record value — NS server name of the third-party hosting. 4.4. If you need to specify another NS server, click **Add** and paste the NS server name. 4.5. Click **Add**. 5. Wait for the NS records to propagate to the DNS servers. Propagation may take up to 72 hours.
