Domain name Whois: how to find contact information?

I use this code fragment for Whois information: I get creation, expiration dates, registrar and name servers but there is no data related to administrative or technical contacts. Is there any way to get them?

I use this code fragment for Whois information:

org.apache.commons.net.whois.WhoisClient whois = new org.apache.commons.net.whois.WhoisClient(); whois.connect("whois.verisign-grs.com", 43); String domainWhois = whois.query(domainName); whois.disconnect();

I get creation, expiration dates, registrar and name servers but there is no data related to administrative or technical contacts. Is there any way to get them?

Generally, finding the owner/administrator of a particular .com or .net domain involves performing two WHOIS lookups.

Verisign is the registry for these top-level domains. The code in your question is correct in that you must query the server at whois.verisign-grs.com.

However, you should be aware that this is a thin WHOIS service. This means that the server will only send you back information about the registrar (the company that the domain is registered through), as well as expiry dates, name servers, and so on.

Using stackoverflow.com as an example, Verisign tells you that the registrar is NAME.COM INC (I'm using the whois program that's found on Unix-based systems, specifying the host with -h for clarity):

$ whois -h whois.verisign-grs.com stackoverflow.com Whois Server Version 2.0 Domain names in the .com and .net domains can now be registered with many different competing registrars. Go to http://www.internic.net for detailed information. Domain Name: STACKOVERFLOW.COM Registrar: NAME.COM, INC. Sponsoring Registrar IANA ID: 625 Whois Server: whois.name.com Referral URL: http://www.name.com Name Server: NS-1033.AWSDNS-01.ORG Name Server: NS-1543.AWSDNS-00.CO.UK Name Server: NS-358.AWSDNS-44.COM Name Server: NS-739.AWSDNS-28.NET Status: clientTransferProhibited https://icann.org/epp#clientTransferProhibited Updated Date: 08-jun-2016 Creation Date: 26-dec-2003 Expiration Date: 26-dec-2016 [...]

If you want to see information about the company or individual that actually owns the domain, you need to send the query to the registrar's WHOIS server. In this case the query must go to whois.name.com:

$ whois -h whois.name.com stackoverflow.com Domain Name: STACKOVERFLOW.COM Registry Domain ID: 108907621_DOMAIN_COM-VRSN Registrar WHOIS Server: whois.name.com Registrar URL: http://www.name.com Updated Date: 2016-06-08T04:23:11Z Creation Date: 2003-12-26T19:18:07Z Registrar Registration Expiration Date: 2016-12-26T19:18:07Z Registrar: Name.com, Inc.
