val __bin_read_t__ : (int -> t) Core_kernel.Bin_prot.Read.reader
val hash_fold_t : Base.Hash.state -> t -> Base.Hash.state
val hash : t -> Base.Hash.hash_value
val sexp_of_t : t -> Sexplib.Sexp.t
val t_of_sexp : Core_kernel.Sexp.t -> t

t_of_sexp is deprecated because it used to block to do a DNS lookup, and we don't want a sexp converter to do that. As we transition away, one can use Blocking_sexp, which has the old behavior.

  • deprecated [since 2015-10] Replace [t] by [Blocking_sexp.t]
module Blocking_sexp = Core.Unix.Inet_addr.Blocking_sexp

Blocking_sexp performs DNS lookup to resolve hostnames to IP addresses.

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
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).

module Replace_polymorphic_compare = Core.Unix.Inet_addr.Replace_polymorphic_compare
val of_string : string -> t

Conversion from the printable representation of an Internet address to its internal representation. The argument string consists of 4 numbers separated by periods (XXX.YYY.ZZZ.TTT) for IPv4 addresses, and up to 8 numbers separated by colons for IPv6 addresses. Raise Failure when given a string that does not match these formats.

val to_string : t -> string

Return the printable representation of the given Internet address. See of_string for a description of the printable representation.

val bind_any : t

A special address, for use only with bind, representing all the Internet addresses that the host machine possesses.

val bind_any_inet6 : t
val localhost : t

Special addresses representing the host machine.

127.0.0.1

val localhost_inet6 : t

(::1)

val inet4_addr_of_int32 : Core_kernel.Int32.t -> t

Some things (like the kernel) report addresses as hex or decimal strings. Provide conversion functions.

val inet4_addr_to_int32_exn : t -> Core_kernel.Int32.t

inet4_addr_to_int32_exn t = 0l when t = Inet_addr.of_string ("0.0.0.0"). An exception is raised if t is a not an IPv4 address.

val inet4_addr_of_int63 : Core_kernel.Int63.t -> t
val inet4_addr_to_int63_exn : t -> Core_kernel.Int63.t
val of_string_or_getbyname : string -> t Async_kernel.Deferred.t

of_string_or_getbyname hostname does a DNS lookup of hostname and returns the resulting IP address.
