[Create a token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/). **Example:**`Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY` API Email + API Key The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key. **Example:**`X-Auth-Email: user@example.com` The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys. **Example:**`X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194` ##### Accepted Permissions (at least one required) `DNS Firewall Write` `DNS Firewall Read` ##### ParametersExpand Collapse dnsFirewallID: string Identifier. maxLength32 params: DNSFirewallGetParams { account\_id } account\_id: string Identifier. maxLength32 ##### ReturnsExpand Collapse DNSFirewallGetResponse { id, deprecate\_any\_requests, dns\_firewall\_ips, 10 more } id: string Identifier. maxLength32 deprecate\_any\_requests: boolean Whether to refuse to answer queries for the ANY type dns\_firewall\_ips: Array<[FirewallIPs](https://developers.cloudflare.com/api/typescript/resources/dns%5Ffirewall#%28resource%29%20dns%5Ffirewall%20%3E%20%28model%29%20firewall%5Fips%20%3E%20%28schema%29)\> ecs\_fallback: boolean Whether to forward client IP (resolver) subnet if no EDNS Client Subnet is sent maximum\_cache\_ttl: number By default, Cloudflare attempts to cache responses for as long as indicated by the TTL received from upstream nameservers. This setting sets an upper bound on this duration. For caching purposes, higher TTLs will be decreased to the maximum value defined by this setting. This setting does not affect the TTL value in the DNS response Cloudflare returns to clients. Cloudflare will always forward the TTL value received from upstream nameservers. maximum36000 minimum30 minimum\_cache\_ttl: number By default, Cloudflare attempts to cache responses for as long as indicated by the TTL received from upstream nameservers. This setting sets a lower bound on this duration. For caching purposes, lower TTLs will be increased to the minimum value defined by this setting. This setting does not affect the TTL value in the DNS response Cloudflare returns to clients. Cloudflare will always forward the TTL value received from upstream nameservers. Note that, even with this setting, there is no guarantee that a response will be cached for at least the specified duration. Cached responses may be removed earlier for capacity or other operational reasons. maximum36000 minimum30 modified\_on: string Last modification of DNS Firewall cluster formatdate-time name: string DNS Firewall cluster name maxLength160 minLength1 negative\_cache\_ttl: number | null This setting controls how long DNS Firewall should cache negative responses (e.g., NXDOMAIN) from the upstream servers. This setting does not affect the TTL value in the DNS response Cloudflare returns to clients. Cloudflare will always forward the TTL value received from upstream nameservers. maximum36000 minimum30 ratelimit: number | null Maximum number of DNS queries per second that will be forwarded to your upstream nameservers. The limit is enforced per server, where each server receives a fraction of the configured value. The actual aggregate rate for a data center may vary depending on how many servers are present. Responses served from cache do not count toward this limit. Set to null to disable rate limiting. maximum1000000000 minimum100 retries: number Number of retries for fetching DNS responses from upstream nameservers (not counting the initial attempt) maximum2 minimum0 upstream\_ips: Array<[UpstreamIPs](https://developers.cloudflare.com/api/typescript/resources/dns%5Ffirewall#%28resource%29%20dns%5Ffirewall%20%3E%20%28model%29%20upstream%5Fips%20%3E%20%28schema%29)\> minLength1 attack\_mitigation?: [AttackMitigation](https://developers.cloudflare.com/api/typescript/resources/dns%5Ffirewall#%28resource%29%20dns%5Ffirewall%20%3E%20%28model%29%20attack%5Fmitigation%20%3E%20%28schema%29) { enabled, only\_when\_upstream\_unhealthy } | null Attack mitigation settings enabled?: boolean When enabled, automatically mitigate random-prefix attacks to protect upstream DNS servers only\_when\_upstream\_unhealthy?: boolean Only mitigate attacks when upstream servers seem unhealthy ### DNS Firewall Cluster Details TypeScript HTTPHTTP TypeScriptTypeScript PythonPython GoGo TerraformTerraform ``` import Cloudflare from 'cloudflare'; const client = new Cloudflare({ apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted }); const dnsFirewall = await client.dnsFirewall.get('023e105f4ecef8ad9ca31a8372d0c353', { account_id: '023e105f4ecef8ad9ca31a8372d0c353', }); console.log(dnsFirewall.id); ``` 200 example ``` { "errors": [ { "code": 1000, "message": "message", "documentation_url": "documentation_url", "source": { "pointer": "pointer" } } ], "messages": [ { "code": 1000, "message": "message", "documentation_url": "documentation_url", "source": { "pointer": "pointer" } } ], "success": true, "result": { "id": "023e105f4ecef8ad9ca31a8372d0c353", "deprecate_any_requests": true, "dns_firewall_ips": [ "203.0.113.1", "203.0.113.254", "2001:DB8:AB::CF", "2001:DB8:CD::CF" ], "ecs_fallback": false, "maximum_cache_ttl": 900, "minimum_cache_ttl": 60, "modified_on": "2014-01-01T05:20:00.12345Z", "name": "My Awesome DNS Firewall cluster", "negative_cache_ttl": 900, "ratelimit": 600, "retries": 2, "upstream_ips": [ "192.0.2.1", "198.51.100.1", "2001:DB8:100::CF" ], "attack_mitigation": { "enabled": true, "only_when_upstream_unhealthy": false } } } ``` ##### Returns Examples 200 example ``` { "errors": [ { "code": 1000, "message": "message", "documentation_url": "documentation_url", "source": { "pointer": "pointer" } } ], "messages": [ { "code": 1000, "message": "message", "documentation_url": "documentation_url", "source": { "pointer": "pointer" } } ], "success": true, "result": { "id": "023e105f4ecef8ad9ca31a8372d0c353", "deprecate_any_requests": true, "dns_firewall_ips": [ "203.0.113.1", "203.0.113.254", "2001:DB8:AB::CF", "2001:DB8:CD::CF" ], "ecs_fallback": false, "maximum_cache_ttl": 900, "minimum_cache_ttl": 60, "modified_on": "2014-01-01T05:20:00.12345Z", "name": "My Awesome DNS Firewall cluster", "negative_cache_ttl": 900, "ratelimit": 600, "retries": 2, "upstream_ips": [ "192.0.2.1", "198.51.100.1", "2001:DB8:100::CF" ], "attack_mitigation": { "enabled": true, "only_when_upstream_unhealthy": false } } } ```
