# Add DNS record

If a network is connected to a zone, A or AAAA records in the zone are added automatically when a port is created in the network. Such records are marked with the **Auto** tag. A or AAAA records can also be added manually. CNAME, MX, and TXT records can only be added manually.

For a domain name, only one record of each type can exist. If you don't have a resource record of the required type for the domain name yet, [add a record](#add-record). If you already have a record of the required type for the domain name, [add a value to it](#add-value-to-record).

If a network is connected to a zone and you have added an A or AAAA record for a domain name manually, and then created a port with this domain name, the port's IP address will be automatically added to this record as an additional value. The record will be marked with the **Auto** tag, and it will begin changing automatically when port data changes.

You can check if a network is connected to a zone in the [control panel](https://my.selectel.ru/vpc/default/private-dns/): from the top menu, click **Products** → **Cloud Servers** → **Private DNS** → **DNS Resolvers** tab → network row → **DNS Zone** field.

## Add record \{#add-record}

<Tabs queryString="add-record">
  <TabItem value="a" default>
    <TabItemLabel>
      A or AAAA
    </TabItemLabel>

    1. In the [control panel](https://my.selectel.ru/vpc/default/private-dns/), from the top menu, click **Products** and select **Cloud Servers**.
    2. Go to the **Private DNS** section.
    3. Open the zone page.
    4. In the **Records** block, click **Add record**.
    5. Select the record type — A or AAAA.
    6. Enter the domain name for which the record will be created. The domain of the zone where you are creating the record will be added to it automatically.
    7. Enter the IP addresses that will be associated with the domain name: IPv4 addresses for an A record, and IPv6 addresses for an AAAA record. You can specify no more than 100 IP addresses. Enter the addresses separated by a comma or a space, or on a new line.
    8. Enter the record TTL in seconds. To apply the zone TTL, enter `-1` or click **Use zone TTL**. TTL is the time during which a resource record in the NS server cache is considered valid and does not require re-caching.
    9. Click **Add**.
