arinwhois.net's Issues

Reassigned Blocks Returns Null Response

I've found a bug with reassigned blocks that causes the return object to be null.

string foundIpAddress = "40.107.14.45";
ArinClient arinClient = new ArinClient();
Response ipResponse = arinClient.QueryIpAsync(IPAddress.Parse(foundIpAddress)).Result;

The ipResponse object will be null when it is accessed and I believe that this is because the return from ARIN is not in the serialised type that the ARIN Client is expecting. In other words, it obtains data but not in the JSON form that it's expecting.

Below is the content from ARIN, so it's generating a response:

So far, this seems specific to all reassigned blocks.

Resolving 4.4.4.4 to Organization using the handle does not resolve

The following code does not provide the same output as whois.arin.net (when IP = 4.4.4.4) and throws an exception:

ArinWhois.Client.ArinClient myArinClient = new ArinWhois.Client.ArinClient();
var myWhoIsResults = myArinClient.QueryIpAsync(IP).Result;

var myWhoIsOrgResults = myArinClient.QueryResourceAsync(myWhoIsResults.Network.OrgRef.Handle, ArinWhois.Client.ArinClient.ResourceType.Organization).Result;

mywhoisorgname = myWhoIsOrgResults.Organization.Name.Value;
mywhoisorgcity = myWhoIsOrgResults.Organization.City.Value;
mywhoisorgpostalcode = myWhoIsOrgResults.Organization.PostalCode.Value;
mywhoispocrawlink = myWhoIsOrgResults.PointOfContact.Ref.Value;
