	// ToFQDN allows whitelisting DNS names in place of IPs. The IPs that result
	// from DNS resolution of `ToFQDN.MatchName`s are added to the same
	// EgressRule object as ToCIDRSet entries, and behave accordingly. Any L4 and
	// L7 rules within this EgressRule will also apply to these IPs.
	// 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.
