    <p>I'm developing a simple app in c#, that can check if a domain name is available to puchase for a specific tld. The method: I downloaded a whois-server list, I send the domain name to its whois server with a TCP client on the protocol 43, and check the servers answer. The problem: more countries has the same whois server: "whois.ripe.net" . If I send the full domain name(with tld), the server's answer is always "No entries found in source RIPE.". If I send the domain name without tld, I dont get any tld specific data about the status of the domain name. </p> <p>The method I use:</p> <pre><code>private string GetWhoisInformation(string whoisServer, string url) { try { StringBuilder stringBuilderResult = new StringBuilder(); TcpClient tcpClinetWhois = new TcpClient(whoisServer, 43); NetworkStream networkStreamWhois = tcpClinetWhois.GetStream(); BufferedStream bufferedStreamWhois = new BufferedStream(networkStreamWhois); StreamWriter streamWriter = new StreamWriter(bufferedStreamWhois); streamWriter.WriteLine(url); streamWriter.Flush(); StreamReader streamReaderReceive = new StreamReader(bufferedStreamWhois); while (!streamReaderReceive.EndOfStream) stringBuilderResult.AppendLine(streamReaderReceive.ReadLine()); return stringBuilderResult.ToString(); } catch { return "lekérdezés sikertelen"; } } </code></pre> <p>Example: I do:</p> <pre><code>GetWhoisInformation("whois.ripe.net", "pokerstars.hu") </code></pre> <p>The server's answer:</p> <pre><code>%ERROR:101: no entries found % % No entries found in source RIPE. </code></pre> <p>for the next command:</p> <pre><code>GetWhoisInformation("whois.ripe.net", "pokerstars") </code></pre> <p>the result contains several blocks like this:</p> <pre><code>% Information related to '80.65.254.128 - 80.65.254.159' inetnum: 80.65.254.128 - 80.65.254.159 netname: Pokerstars descr: Hosting country: GB admin-c: DC77-RIPE tech-c: JM2352-RIPE status: assigned PA mnt-by: manx-telecom-mnt changed: bill.hogg@manx-telecom.com 20101123 source: RIPE </code></pre> <p>There's no information about the domain name "pokerstars.hu". Of course, I get exactly the same answers if I want to check pokerstars.va. Pokerstars.hu is a registred domain, pokerstars.va is not.</p> <p>How can I find the correct status of a domain name?</p>

    1. CODoesn't the RIPE whois server have nothing to do with domain names? It's for IP addresses and network resources (like ASNs, etc...). Are you sure you are supposed to be using this whois server for ccTLD queries?

    2. COIt is in the same list with good, working whois servers. It is supposed to work. At some countries, I dont find alternative whois servers. Every 'up to date' whois server list contains a lot of RIPE records.

    3. CO@Celada I can't argue with you never having heard of RIPE till this question but the server he uses describes itself as WHOIS2 in responses.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
