As an exercise, I've written my own IP echo service and am running it at ip.ericb.me.

Its excruciatingly simple Clojure source looks something like the following. 

(defroutes app
  (GET "/" {{x-real-ip "x-real-ip"} :headers}
    {:status  200
     :headers {"Content-Type" "text/plain"}
     :body    x-real-ip}))

(defn -main [& args]
  (->> (or (some-> (env :port) (Integer/parseInt)) 5000)
       (hash-map :port)
       (run-server app)))
