A Clojure library that wraps dnsjava with a better api.
(:require [clj-dnsjava.core :as dns])
;; defaults to looking up A records
(dns/ns-lookup "google.com")
=> [{:type :a, :name "google.com.", :ttl 249, :address "216.58.217.110"}]
;; record keywords are found in clj-dnsjava.core/keyword-type
(dns/ns-lookup "google.com" :aaaa)
=> [{:type :aaaa, :name "google.com.", :ttl 298, :address "2607:f8b0:4004:80c:0:0:0:200e"}]
;; supports different order for args
(clojure.pprint/print-table (dns/ns-lookup :mx "google.com"))
=>
| :type | :name | :ttl | :addl-name | :priority | :target |
|-------+-------------+------+--------------------------+-----------+--------------------------|
| :mx | google.com. | 492 | alt2.aspmx.l.google.com. | 30 | alt2.aspmx.l.google.com. |

| :mx | google.com. | 492 | alt1.aspmx.l.google.com. | 20 | alt1.aspmx.l.google.com. |
