func GetCIDRLabels ¶

func GetCIDRLabels(prefix netip.Prefix) labels.Labels

GetCIDRLabels turns a CIDR into a set of labels representing the cidr itself and all broader CIDRS which include the specified CIDR in them. For example: CIDR: 10.0.0.0/8 =>

"cidr:10.0.0.0/8", "cidr:10.0.0.0/7", "cidr:8.0.0.0/6",
"cidr:8.0.0.0/5", "cidr:0.0.0.0/4, "cidr:0.0.0.0/3",
"cidr:0.0.0.0/2",  "cidr:0.0.0.0/1",  "cidr:0.0.0.0/0"

The identity reserved:world is always added as it includes any CIDR.

func IPStringToLabel ¶

func IPStringToLabel(ip string) (labels.Label, error)

IPStringToLabel parses a string and returns it as a CIDR label.

If ip is not a valid IP address or CIDR Prefix, returns an error.
