A representation of CIDR netmasks (e.g. "192.168.0.0/24") and functions to match if a given address is inside the range or not. Only IPv4 addresses are supported. Values are always normalized so the base address is the lowest IP address in the range, so for example to_string (of_string "192.168.1.101/24") = "192.168.1.0/24".

of_string Generates a Cidr.t based on a string like "10.0.0.0/8". Addresses are not expanded, i.e. "10/8" is invalid.

val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val create : base_address:Unix.inet_addr -> bits:int -> t

Accessors.

  • base_address 192.168.0.0/24 = 192.168.0.0
  • bits 192.168.0.0/24 = 24.
val bits : t -> int
val all_matching_addresses : t -> Unix.inet_addr Core_kernel.Sequence.t

Generate a sequence of all addresses in the block.

val multicast : t

IPv4 multicast address can be represented by the CIDR prefix 224.0.0.0/4, (i.e. addresses from 224.0.0.0 to 239.255.255.255, inclusive)

val does_match : t -> Unix.inet_addr -> bool

Is the given address inside the given Cidr.t? Note that the broadcast and network addresses are considered valid so does_match 10.0.0.0/8 10.0.0.0 is true.

val netmask_of_bits : t -> Unix.inet_addr

Return the netmask corresponding to the number of network bits in the CIDR. For example, the netmask for a CIDR with 24 network bits (e.g. 1.2.3.0/24) is 255.255.255.0.

val is_subset : t -> of_:t -> bool

is_subset t1 ~of:t2 is true iff the set of IP addresses specified by t1 is a subset of those specified by t2.

If is_subset t1 ~of_:t2, then does_match t1 x implies does_match t2 x.

If does_match t1 x and does_match t2 x, then either is_subset t1 ~of_:t2 or is_subset t2 ~of_:t1 (or both).
