## Update Address Map

**patch** `/accounts/{account_id}/addressing/address_maps/{address_map_id}`

Modify properties of an address map owned by the account.

### Path Parameters

- `account_id: string`

  Identifier of a Cloudflare account.

- `address_map_id: string`

  Identifier of an Address Map.

### Body Parameters

- `default_sni: optional string`

  If you have legacy TLS clients which do not send the TLS server name indicator, then you can specify one default SNI on the map. If Cloudflare receives a TLS handshake from a client without an SNI, it will respond with the default SNI on those IPs. The default SNI can be any valid zone or subdomain owned by the account.

- `description: optional string`

  An optional description field which may be used to describe the types of IPs or zones on the map.

- `enabled: optional boolean`

  Whether the Address Map is enabled or not. Cloudflare's DNS will not respond with IP addresses on an Address Map until the map is enabled.

### Returns

- `errors: array of  { code, message, documentation_url, source }`

  - `code: number`

  - `message: string`

  - `documentation_url: optional string`

  - `source: optional  { pointer }`

  - `documentation_url: optional string`

  - `source: optional  { pointer }`

- `success: true`

  - `true`

- `result: optional AddressMap`

  - `id: optional string`

    Identifier of an Address Map.

  - `can_delete: optional boolean`

    If set to false, then the Address Map cannot be deleted via API. This is true for Cloudflare-managed maps.

  - `can_modify_ips: optional boolean`

    If set to false, then the IPs on the Address Map cannot be modified via the API. This is true for Cloudflare-managed maps.

  - `created_at: optional string`
