Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Whenever you use WHOIS command doesn't return any usefully information. I usually have to go to Godaddy, Dnsstuff or other services to get the data. I understand the reason is mostly due to spamming.

I was just wondering how other services get this data. Do they use different type of WHOIS command? Also confused about some of the data generated data from WHOIS command is just spam. Example doing whois google.com geneates spam website such as GOOGLE.COM.ZZZZZZ.THE.BEST.WEBHOSTING.AT.WWW.FATUCH.COM. Where is this data come from?

Exmaple:

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.

GOOGLE.COM.ZZZZZZ.THE.BEST.WEBHOSTING.AT.WWW.FATUCH.COM

The short answer to your question, assuming you are using the debian/ubuntu whois library, is to use

$ whois -h whois.crsnic.net "domain google.com"

Here's the long answer.

The .COM TLD is a Thin WHOIS. When you peform a WHOIS query, the WHOIS tool first sends a WHOIS query to Verisign (hostname whois.crsnic.net) and extract the referral from the the response.

By default, when you query Verisign from the domain example.com, Whois performs a very broad search of the string "example.com" in several different objects including the domain name, the registrar name and the nameservers.

You can refine the query by specifying a keyword, as described in the Verisign documentation. http://registrar.verisign-grs.com/whois/iframe/help.html?ppath=www.verisigninc.com/products-and-services/domain-name-services/whois&

The command above does exactly what I explained. Instead of google.com it sends to Verisign the full query "domain google.com". You have to explicitly pass the -h flag because Whois attempts to guess the hostname to query from the query, but it will fail because it won't recognize the query "domain google.com" as a valid domain.

Here's the result of the command.

$ whois -h whois.crsnic.net "domain google.com"

Currently, the authoritative whois server for .COM domain names is whois.verisign-grs.com. So the command should be updated to: whois -h whois.verisign-grs.com "domain google.com" –  iglvzx Jun 5 at 11:20

When you request WHOIS info for google.com, it searches for "google.com" in all records, not anchoring the pattern to the end as you expect.

And it depends on the WHOIS client and which servers it is configured to use. I did some research a couple years ago about setting up an internal WHOIS service (I work at a university, so we have lots of little fiefdoms and lots of networks) and from what I could tell, there was very little consistent structure in the data formats, so clients have to employ lots of heuristics to figure out referrals and such. My guess is that dnsstuff and godaddy just have probably more tuned heuristics. So you might just try a different client.
