ReturnsExpand Collapse

class DNSFirewallListResponse: …

id: str

Identifier.

maxLength32

deprecate_any_requests: bool

Whether to refuse to answer queries for the ANY type

dns_firewall_ips: List[FirewallIPs]

ecs_fallback: bool

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

maximum_cache_ttl: float

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: float

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: datetime

Last modification of DNS Firewall cluster

formatdate-time

name: str

DNS Firewall cluster name

maxLength160

minLength1

negative_cache_ttl: Optional[float]

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: Optional[float]

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

maximum1000000000

minimum100

retries: float

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

maximum2

minimum0

upstream_ips: List[UpstreamIPs]

minLength1

attack_mitigation: Optional[AttackMitigation]

Attack mitigation settings

enabled: Optional[bool]

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

only_when_upstream_unhealthy: Optional[bool]

Only mitigate attacks when upstream servers seem unhealthy
