	// ToFQDN allows whitelisting DNS names in place of IPs. The IPs that result

	// The DNS -> IP mapping is re-resolved periodically from within the
	// cilium-agent, and the IPs in the DNS response are effected in the policy
	// for selected pods as-is (i.e. the list of IPs is not modified in any way).
	// Note: An explicit rule to allow for DNS traffic is needed for the pods, as
	// ToFQDN counts as an egress rule and will enforce egress policy when
	// PolicyEnforcment=default.
	// Note: If the resolved IPs are IPs within the kubernetes cluster, the
	// ToFQDN rule will not apply to that IP.
	// Note: ToFQDN cannot occur in the same policy as other To* rules.
	//
	// The current implementation has a number of limitations:
	// - The DNS resolution originates from cilium-agent, and not from the pods.
	// Differences between the responses seen by cilium agent and a particular
	// pod will whitelist the incorrect IP.
	// - DNS TTLs are ignored, and cilium-agent will repoll on a short interval
	// (5 seconds). Each change to the DNS data will trigger a policy
	// regeneration. This may result in delayed updates to the policy for an
	// endpoint when the data changes often or the system is under load.

Either ingress, egress, or both can be provided. If both ingress and egress are omitted, the rule has no effect.
