ipaddr: IP and MAC address manipulation

A library for manipulation of IP and MAC address representations.

Features:

• ounit2-based tests

• IPv4 and IPv6 support

• IPv4 and IPv6 CIDR prefix support

• IPv4 and IPv6 CIDR-scoped address support

• Ipaddr.V4 and Ipaddr.V4.Prefix modules are Map.OrderedType

• Ipaddr.V6 and Ipaddr.V6.Prefix modules are Map.OrderedType

• Ipaddr and Ipaddr.Prefix modules are Map.OrderedType

• Ipaddr_unix in findlib subpackage ipaddr.unix provides compatibility with the standard library Unix module

• Ipaddr_top in findlib subpackage ipaddr.top provides top-level pretty printers

• IP address scope classification

• IPv4-mapped addresses in IPv6 (::ffff:0:0/96) are an embedding of IPv4

• MAC-48 (Ethernet) address support

• Macaddr is a Map.OrderedType

• All types have sexplib serializers/deserializers optionally via the Ipaddr_sexp and Macaddr_sexp libraries.

Usage

There are the following opam packages included:

• ipaddr: the Ipaddr and associated modules

• ipaddr-sexp

• ipaddr-cstruct

• macaddr: the Macaddr and associated modules.

There are the following ocamlfind libraries included as part of this repository, included as part of the respective opam packages.

• ipaddr: The Ipaddr module for IPv4/6 manipulation.

• ipaddr.top: Toplevel printers for Ipaddr.

• ipaddr-cstruct: The Ipaddr_cstruct module

• macaddr: The Macaddr module for MAC address manipulation.

• macaddr.top: Toplevel printers for Macaddr.

• macaddr-cstruct: The Macaddr_cstruct module

• ipaddr-sexp: S-expression converters for Ipaddr.

• macaddr-sexp: S-expression converters for Macaddr.

Installation and development

The packages are released to the opam-repository. An opam install ipaddr (or any other above mentioned package) will install it. If you want to install the latest development commit, opam pin add ipaddr --dev will do this.

A local build, after a git clone can be done with dune build, a dune runtest compiles and executes the testsuite. If dependencies are missing, opam install (-t) --deps-only . in the cloned directory will install them.

The auto-formatter ocamlformat is used, please execute dune build @fmt --auto-promote before submitting a pull request.
