private async Task QueryByIPAddress()
{
  var result = await WhoisClient.QueryAsync("8.8.8.8", options: default);
  
  Console.WriteLine("{0} - {1}", result.AddressRange.Begin, result.AddressRange.End); // "8.8.8.0 - 8.8.8.255"
  Console.WriteLine("{0}", result.OrganizationName); // "Google Inc. LVLT-GOGL-8-8-8 (NET-8-8-8-0-1)"
  Console.WriteLine(string.Join(" > ", result.RespondedServers)); // "whois.iana.org > whois.arin.net" 
}

private async Task QueryByDomain()
{
  var result = await WhoisClient.QueryAsync("google.com", options: default);
  
  Console.WriteLine("{0}", result.OrganizationName); // "Google Inc."
  Console.WriteLine(string.Join(" > ", result.RespondedServers)); // "whois.iana.org > whois.verisign-grs.com > whois.markmonitor.com" 
}

v.6.0.0
- [BREAKING CHANGE] The Default timeout for communication with servers was changed to 2 seconds, and the default retry count was changed to 3 times (Issue #10 by Makaopior)
- Improved resolving an organization name from a raw response text from a WHOIS server
- Improved that TcpClient creation is moved to a separate function, enabling usage in special cases like flowing traffic through a SOCKS proxy (PR #9 by Makaopior)
- Fixed potential infinite loop in socket reading method (Issue #11, PR #9 by Makaopior)
- Fixed potential response string corruption for registries which use multi-byte encoding (Issue #12, PR #13 by Makaopior)
- Fixed IPv6 address parsing in APNIC response (PR #14 by Makaopior)
