## DNS Firewall Cluster Details

`client.DNSFirewall.Get(ctx, dnsFirewallID, query) (*DNSFirewallGetResponse, error)`

**get** `/accounts/{account_id}/dns_firewall/{dns_firewall_id}`

Show a single DNS Firewall cluster for an account

### Parameters

- `dnsFirewallID string`

  Identifier.

- `query DNSFirewallGetParams`

  - `AccountID param.Field[string]`

    Identifier.

### Returns

- `type DNSFirewallGetResponse struct{…}`

  - `ID string`

    Identifier.

  - `DeprecateAnyRequests bool`

    Whether to refuse to answer queries for the ANY type

  - `DNSFirewallIPs []FirewallIPs`

  - `ECSFallback bool`

    Whether to forward client IP (resolver) subnet if no EDNS Client Subnet is sent

  - `MaximumCacheTTL float64`

    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.

  - `MinimumCacheTTL float64`

    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.

  - `ModifiedOn Time`

    Last modification of DNS Firewall cluster

  - `Name string`

    DNS Firewall cluster name

  - `NegativeCacheTTL float64`

    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.

  - `Ratelimit float64`

    Ratelimit in queries per second per datacenter (applies to DNS queries sent to the upstream nameservers configured on the cluster)

  - `Retries float64`

    Number of retries for fetching DNS responses from upstream nameservers (not counting the initial attempt)

  - `UpstreamIPs []UpstreamIPs`

  - `AttackMitigation AttackMitigation`

    Attack mitigation settings

    - `Enabled bool`

      When enabled, automatically mitigate random-prefix attacks to protect upstream DNS servers

    - `OnlyWhenUpstreamUnhealthy bool`

      Only mitigate attacks when upstream servers seem unhealthy

### Example

```go
package main

import (
  "context"
  "fmt"

  "github.com/cloudflare/cloudflare-go"
  "github.com/cloudflare/cloudflare-go/dns_firewall"
  "github.com/cloudflare/cloudflare-go/option"
)

func main() {
  client := cloudflare.NewClient(
    option.WithAPIToken("Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY"),
  )
  dnsFirewall, err := client.DNSFirewall.Get(
    context.TODO(),
    "023e105f4ecef8ad9ca31a8372d0c353",
    dns_firewall.DNSFirewallGetParams{
      AccountID: cloudflare.F("023e105f4ecef8ad9ca31a8372d0c353"),
    },
  )
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", dnsFirewall.ID)
}
```
