Use import and export to have more control over your DNS records and make processes like migrating a domain or bulk editing [record comments](https://developers.cloudflare.com/dns/manage-dns-records/reference/record-attributes/) easier.

## Import records

Warning

The zone file size limit is 256 KiB (262144 bytes).

### Format your zone file

Create a [BIND zone file](https://en.wikipedia.org/wiki/Zone_file) for your domain. If you need help, use a [third-party tool](https://pgl.yoyo.org/as/bind-zone-file-creator.php).

If you are using certain record types — for example, `CNAME`, `DNAME`, `MX`, `NS`, `PTR`, or `SRV` records — make sure that the **content** of those records contains fully qualified domain names ending in a trailing period (as in `example.com.`). For more details, refer to [RFC 1035](https://www.rfc-editor.org/rfc/rfc1035#section-5.1) or this [post on Stack Exchange](https://superuser.com/questions/348282/fqdn-format-in-bind-zone#348284).

### Import zone file to Cloudflare

* Dashboard

  To import a zone file using the dashboard:

  1. Log in to the [Cloudflare dashboard](https://dash.cloudflare.com) and select your account and domain.
  2. Go to **DNS** > **Records**.
  3. Select **Import and Export**.
  4. For **Import DNS records**, select your [formatted file](#format-your-zone-file).
  5. If you do not want [applicable records](https://developers.cloudflare.com/dns/proxy-status/) proxied, unselect **Proxy imported DNS records**.

* API

  To import records using the API, send a [POST request](https://developers.cloudflare.com/api/resources/dns/subresources/records/methods/import/) with a properly [formatted file](#format-your-zone-file).

***

## Export records

You can also bulk export records from Cloudflare.

* Dashboard

  To export records using the dashboard:

  1. Log in to the [Cloudflare dashboard](https://dash.cloudflare.com) and select your account and domain.
  2. Go to **DNS** > **Records**.
  3. Select **Import and Export**.
  4. Select **Export**.

* API

  To export records using the API, send a [GET request](https://developers.cloudflare.com/api/resources/dns/subresources/records/methods/export/).

## DNS record attributes

When exporting or importing a zone file, Cloudflare formats [comments and tags](https://developers.cloudflare.com/dns/manage-dns-records/reference/record-attributes/) using the following structure, appending the attributes as inline comment using the `;` character after each record in accordance with [RFC 1035 section 5](https://datatracker.ietf.org/doc/html/rfc1035#section-5-1):

| Combination | Description |
| - | - |
| **Only tags** | Tag names contain a [small set](https://developers.cloudflare.com/dns/manage-dns-records/reference/record-attributes/#tags) of characters. Additionally, tag values must be contained by a double quote (`"`) if they contain `"`, `=`, `,`, or `\`. When enclosed within double quotes (`"`), tag values are represented as JSON strings, so other quotes within the value can be escaped as `\"`. A tag with an empty value can be represented either as `my-tag-name:""`, `my-tag-name:`, or `my-tag-name`. |
| **Only a comment** | Comments have [fewer limitations](https://developers.cloudflare.com/dns/manage-dns-records/reference/record-attributes/#comments) on characters, meaning that the comment is included verbatim. If the comment includes the string `cf_tags=`, you need to include an additional `cf_tags=` at the end of the line. |
| **Comment and tags** | The zone file comment would be of the form ; `<comment>` cf\_tags=`<tags>`, as described above. Note the added space character before `cf_tags=`. |
| **Neither attribute** | The comment in the zone file may be empty or omitted entirely. Comments in the zone file that do not immediately follow a record are also ignored. |

```txt
; Only tags
a.example.com.  60  IN  A   1.1.1.1 ;   cf_tags=awesome
b.example.com.  60  IN  A   1.1.1.1 ;   cf_tags=tag1,tag2:value2,tag3:"value,with,commas",tag4:"value with \"escaped\" quotation marks"


; Only a comment
c.example.com.  60  IN  A   1.1.1.1 ; just a comment without tags
d.example.com.  60  IN  A   1.1.1.1 ; this comment contains cf_tags= as text cf_tags=


; Comments and tags
e.example.com.  60  IN  A   1.1.1.1 ; simple example cf_tags=important,ticket:THIS-12345
f.example.com.  60  IN  A   1.1.1.1 ; this is the comment cf_tags=tag1:value1,tag2:value2,tag-without-value,another-tag-without-value,tag-with-quoted-value:"because of the comma, quotes are needed"


; Neither attribute
g.example.com.  60  IN  A   1.1.1.1
```

### Reserved cf- tags

When exporting and importing, special tags starting by `cf-` allow you to control specific Cloudflare configurations. On export, these tags are automatically added to reflect the current configuration for each record on your zone.

```txt
;; CNAME Records
a.cloudflaredocs.com.  1  IN  CNAME  example.com. ; cf_tags=test:1,cf-flatten-cname
b.cloudflaredocs.com.  1  IN  CNAME  example.com. ; cf_tags=cf-proxied:false
c.cloudflaredocs.com.  1  IN  CNAME  example.com. ; cf_tags=tag-without-value,cf-proxied:true
```

#### cf-proxied

On export, [proxied DNS records](https://developers.cloudflare.com/dns/proxy-status/) will present a tag `cf-proxied:true` while DNS-only records will have this tag set to `cf-proxied:false`.

When importing zone files, the value in the `cf-proxied` tag will take precedence in determining whether a record should be proxied. This means that:

* If the tag is present, its value will be considered for the respective record regardless of the **Proxy imported DNS records** option being selected (via dashboard), or the `proxied` parameter being generally set to `true` or `false` (via API).
* If the tag is absent, the proxied status will fall back to the general import option, meaning **Proxy imported DNS records** selected or not (via dashboard) or the `proxied` parameter set to `true` or `false` (via API).

#### cf-flatten-cname

If you are on a paid zone and want to use [Per-record CNAME flattening](https://developers.cloudflare.com/dns/cname-flattening/set-up-cname-flattening/#per-record), use the tag `cf-flatten-cname` next to each flattened CNAME record in your zone file. On export, this tag is automatically added to reflect the record configuration that you have on your zone.

## DNS zone file directives

A DNS zone file can be constructed using directives in addition to resource records (RRs). Directives start with `$` and are standardized - `$ORIGIN` and `$INCLUDE` are defined in [RFC 1035](https://www.rfc-editor.org/rfc/rfc1035#section-5.1), and `$TTL` is defined in [RFC 2308](https://www.rfc-editor.org/rfc/rfc2308). Additionally, BIND provides the [non-standard](https://bind9.readthedocs.io/en/latest/chapter3.html#bind-primary-file-extension-the-generate-directive) `$GENERATE` directive.

Cloudflare supports `$ORIGIN`, `$TTL`, and `$GENERATE` directives.

`$INCLUDE` is not supported. When a zone file contains a `$INCLUDE` directive, Cloudflare responds with a parsing error `$INCLUDE directive not allowed`.
