我正在开发一个小域检查器，我无法让.SE工作：
public string Lookup(string domain, RecordType recordType, SeoToolsSettings.Tld tld)
{
TcpClient tcp = new TcpClient();
tcp.Connect(tld.WhoIsServer, 43);
string strDomain = recordType.ToString() + " " + domain + "\r\n";
byte[] bytDomain = Encoding.ASCII.GetBytes(strDomain.ToCharArray());
Stream s = tcp.GetStream();
s.Write(bytDomain, 0, strDomain.Length);
StreamReader sr = new StreamReader(tcp.GetStream(), Encoding.ASCII);
string strLine = "";
StringBuilder builder = new StringBuilder();
while (null != (strLine = sr.ReadLine()))
{
builder.AppendLine(strLine);
}
tcp.Close();
if (tld.WhoIsDelayMs > 0) System.Threading.Thread.Sleep(tld.WhoIsDelayMs);
return builder.ToString();
}
我已经尝试过Whois服务器whois.nic-se.se和whois.iis.se让我不断得到：

"domain google.se" not found.
编辑：
我尝试过更改为UTF8而没有其他结果。
当我尝试使用sysinternals中的whois时，我得到了正确的结果，但没有使用我的代码，甚至没有使用SE.whois-servers.net。

嗯，在我的Mac上执行whois google.se时，我得到以下内容：

所以它可能只是你的代码。也许您必须以非ASCII编码方式执行请求，例如UTF8？
答案 1 :(得分：1)
我终于解决了它。
使用wireshark，我看到来自sysinternals的whois没有添加“DOMAIN”部分：
string strDomain = recordType.ToString（）+“”+ domain +“\ r \ n”;
（recordType.ToString ==“DOMAIN”）。
所以当我删除它时，它有效！

没有查看您的代码，为什么不：
这将为您提供par.se
IP Found:
- 193.13.249.142
Host name:
- parweb1.par.se
Aliases:
none
IP address list:
- 193.13.249.142
如果您只想要IP的 RIPE信息，您也可以使用我的页面进行测试
http://balexandre.com/iplookup.aspx?ip= {ip to test}
按钮事件
protected void btnCheck_Click(object sender, EventArgs e)
{
DomainCheck domain = new DomainCheck();
string ip = domain.GetIPFromDomain(txtDomain.Text.Trim());
litResponse.Text = String.Format(
"IP{0} Found:<br/> - <strong>{1}</strong><br/>{2}",
ip.Contains(",") ? "'s" : "",
ip.Replace(",", "<br/> - "), domain.VerifyIP(ip));
}
DomainCheck代码：
public class DomainCheck
{
public DomainCheck() { }
public string VerifyIP(string ipAddress)
{
if (String.IsNullOrEmpty(ipAddress))
return "IP Address is invalid!";
string r = "";
if (ipAddress.Contains(","))
{
foreach (string ip in ipAddress.Split(','))
r += String.Format("<br/><br/>#### <em>Checking {0}</em>{1}", ip, CheckIPAddress(ip));
}
else
r += CheckIPAddress(ipAddress);
return r;
}
public string GetIPFromDomain(string hostname)
{
string r = "";
IPAddress[] addresslist = Dns.GetHostAddresses(hostname);
foreach (IPAddress theaddress in addresslist)
{
r += String.Format("{0},", theaddress.ToString());
}
return String.IsNullOrEmpty(r) ? null : r.TrimEnd(',');
}
private string CheckIPAddress(string ipAddress)
{
string r = "";
try
{
IPAddress hostIPAddress = IPAddress.Parse(ipAddress);
IPHostEntry hostInfo = Dns.GetHostByAddress(hostIPAddress);
// Get the IP address list that resolves to the host names contained in
// the Alias property.
IPAddress[] address = hostInfo.AddressList;
// Get the alias names of the addresses in the IP address list.
String[] alias = hostInfo.Aliases;
r += String.Format(
"<br/>Host name: <br/>- <strong>{0}</strong><br/>Aliases: ",
hostInfo.HostName);
if (alias.Length == 0)
r += "<br/><em>none</em>";
else
for (int index = 0; index < alias.Length; index++)
r += String.Format("<br/>- <strong>{0}</strong>", alias[index]);
r += "<br/>IP address list: ";
if (address.Length == 0)
r += "<br/><em>none</em>";
else

r += String.Format("<br/>- <strong>{0}</strong>", address[index]);
}
catch (SocketException e)

e.Source, e.Message);
}
catch (FormatException e)
