Type of ordered address scope classifications

val scope_of_sexp : Sexplib.Sexp.t -> scope

val sexp_of_scope : scope -> Sexplib.Sexp.t

module V4 : sig ... end

A collection of functions for IPv4 addresses.

module V6 : sig ... end

A collection of functions for IPv6 addresses.

type ('v4, 'v6) v4v6 =

| V4 of 'v4
| V6 of 'v6

Type of either an IPv4 value or an IPv6 value

val v4v6_of_sexp : 
  (Sexplib.Sexp.t -> 'v4) ->
  (Sexplib.Sexp.t -> 'v6) ->
  Sexplib.Sexp.t ->
  ('v4, 'v6) v4v6

val sexp_of_v4v6 : 
  ('v4 -> Sexplib.Sexp.t) ->
  ('v6 -> Sexplib.Sexp.t) ->
  ('v4, 'v6) v4v6 ->
  Sexplib.Sexp.t

type t = (V4.t, V6.t) v4v6

Type of any IP address

val t_of_sexp : Sexplib.Sexp.t -> t

val sexp_of_t : t -> Sexplib.Sexp.t

val to_string : t -> string

to_string addr is the text string representation of addr.

val to_buffer : Buffer.t -> t -> unit

to_buffer buf addr writes the text string representation of addr into buf.

val pp_hum : Format.formatter -> t -> unit

pp_hum f ip outputs a human-readable representation of ip to the formatter f.

val of_string_exn : string -> t

of_string_exn s parses s as an IPv4 or IPv6 address. Raises Parse_error if s is not a valid string representation of an IP address.

val of_string : string -> t option

Same as of_string_exn but returns an option type instead of raising an exception.

val of_string_raw : string -> int Pervasives.ref -> t

Same as of_string_exn but takes as an extra argument the offset into the string for reading.

val v4_of_v6 : V6.t -> V4.t option

v4_of_v6 ipv6 is the IPv4 representation of the IPv6 address ipv6. If ipv6 is not an IPv4-mapped address, None is returned.

val to_v4 : t -> V4.t option

to_v4 addr is the IPv4 representation of addr.

val v6_of_v4 : V4.t -> V6.t

v6_of_v4 ipv4 is the IPv6 representation of the IPv4 address ipv4.

val to_v6 : t -> V6.t

to_v6 addr is the IPv6 representation of addr.

val scope : t -> scope

scope addr is the classification of addr by the scope hierarchy.

val is_global : t -> bool

is_global addr is a predicate indicating whether addr globally addresses a node.

val is_multicast : t -> bool

is_multicast addr is a predicate indicating whether addr is a multicast address.

val is_private : t -> bool

is_private addr is a predicate indicating whether addr privately addresses a node.

val multicast_to_mac : t -> Macaddr.t

multicast_to_mac addr is the MAC address corresponding to the multicast address addr. See V4.multicast_to_mac and V6.multicast_to_mac.

val to_domain_name : t -> string list

to_domain_name addr is the domain name label list for reverse lookups of addr. This includes the .arpa. suffix.

module Prefix : sig ... end

include Map.OrderedType with type t := t

val compare : t -> t -> int

A total ordering function over the keys. This is a two-argument function f such that f e1 e2 is zero if the keys e1 and e2 are equal, f e1 e2 is strictly negative if e1 is smaller than e2, and f e1 e2 is strictly positive if e1 is greater than e2. Example: a suitable ordering function is the generic structural comparison function Pervasives.compare.
