MAC vendor lookup

MAC vendor lookup
You are encouraged to solve this task according to the task description, using any language you may know.

Every connected device around the world comes with a unique Media Access Control address, or a MAC address. A common task a network administrator may come across is being able to identify a network device's manufacturer when given only a MAC address.

Basic Task

The task is to interface with one (or numerous) APIs that exist on the internet and retrieve the device manufacturer based on a supplied MAC address.

A MAC address that does not return a valid result should return the String "N/A". A error related to the network connectivity or the API should return a null result.

C#

<lang csharp>using System; using System.Net; using System.Net.Http; using System.Threading.Tasks;

class Program {

   static async Task<string> LookupMac(string MacAddress)
   {
       var uri = new Uri("http://api.macvendors.com/" + WebUtility.UrlEncode(MacAddress));
       using (var wc = new HttpClient())
           return await wc.GetStringAsync(uri);
   }
   static void Main(string[] args)
   {
       foreach (var mac in new string[] { "88:53:2E:67:07:BE", "FC:FB:FB:01:FA:21", "D4:F4:6F:C9:EF:8D" })
           Console.WriteLine(mac + "\t" + LookupMac(mac).Result);
       Console.ReadLine();
   }

}</lang>

Output:

88:53:2E:67:07:BE       Intel Corporate
FC:FB:FB:01:FA:21       Cisco Systems, Inc
D4:F4:6F:C9:EF:8D       Apple, Inc.

zkl

Translation of: Lua

Uses libcurl (the multiprotocol file transfer library) to do the web query <lang zkl>var [const] CURL=Import("zklCurl"); // libcurl const MAC_VENDORS="http://api.macvendors.com/";

fcn lookUp(macAddress){

  httpAddr:=MAC_VENDORS + macAddress;
  vender:=CURL().get(httpAddr); //-->(Data,bytes of header,bytes of trailer)
  vender=vender[0].del(0,vender[1]);  // remove HTTP header
  vender.text;		// Data --> String (Data is a byte bucket)

}</lang> <lang zkl>lookUp("FC-A1-3E-2A-1C-33").println(); lookUp("4c:72:b9:56:fe:bc").println(); lookUp("foobar").println();</lang>
