Clj-ip

A Clojure library designed to for testing whether an IP address is part of a subnet.

Usage

Add the following to your dependencies:

[functionalbytes/clj-ip "0.9.0"]

Require the clj.ip namespace and simply use the has-ip? function on two Strings, like so:

(require [clj.ip :refer (has-ip? compile)])

(has-ip? "192.168.0.0/24" "192.168.0.54")
;=> true

When a subnet/range is used many times, it can be compiled to a faster version, using compile. A compiled version can also be used as a predicate function.

(def subnet (compile "192.168.0.0/24")

(has-ip? subnet "192.168.1.54")
;=> false

(subnet "192.168.0.54")
;=> true
