Net::Whois - Whois parser checks domain data, determines if domain is registered or not

Whois parser overview​

img

Data is collected via the WHOIS protocol from central servers for each domain zone. More about WHOIS can be read on Wikipedia: http://en.wikipedia.org/wiki/WHOIS

A-Parser functionality allows you to save parsing settings for further use (presets), set a parsing schedule, and much more. You can use automatic query replication, substitution of subqueries from files, enumeration of alphanumeric combinations and lists to obtain the maximum possible number of results.

Saving results is possible in the form and structure that you need, thanks to the built-in powerful Template Toolkit template engine that allows you to apply additional logic to results and output data in various formats, including JSON, SQL, and CSV.

Data collected​

  • Whether the domain is registered or not
  • Date of domain registration expiration
  • When the domain was registered
  • Used whois service
  • List of domain name servers
  • Current domain status
  • Domain release date

Usage options​

  • Collecting free domains or those that will soon become available
  • Collecting a list of ns-servers
  • Obtaining domain statuses

Capabilities​

  • Supports working with international domains (IDN, for example, yandex.rf)

Queries​

  • As queries, it is necessary to specify the domain of the site being searched, for example:
a-parser.com  
yandex.ru  
google.com  
vk.com  
facebook.com

Results​

  • As a result, the domain is displayed, whether it is registered, the date of registration expiration, and the date of domain registration:
facebook.com - registered: 1, expire: 30.03.2028, creation: 29.03.1997
a-parser.com - registered: 1, expire: 25.02.2022, creation: 25.02.2012
vk.com - registered: 1, expire: 23.06.2021, creation: 24.06.1997
yandex.ru - registered: 1, expire: 01.10.2021, creation: 23.09.1997
google.com - registered: 1, expire: 14.09.2028, creation: 15.09.1997

Output options​

Output of domain expiration data in CSV​

Result format:

[% tools.CSVline(query, registered, expire_date, creation_date, free_date, whoisserver, registrar) %]

Example result:

a-parser.com,1,25.02.2022,25.02.2012,none,whois.crsnic.net,"PDR Ltd. d/b/a PublicDomainRegistry.com"

Output of NS list​

Result format:

$ns.format('$server\n')

Example result:

demi.ns.cloudflare.com
vern.ns.cloudflare.com

Output of NS list in CSV​

Result format:

[% FOREACH ns;
  tools.CSVline(query, server);
END; %]

Example result:

a-parser.com,demi.ns.cloudflare.com
a-parser.com,vern.ns.cloudflare.com

Output of result in JSON​

Initial text:

[% data = {} %]

Final text:

[% data.json %]

Result format:

[%  data = {};
    data.query = query;
    data.registered = registered;
    data.expire_date = expire_date;
    data.creation_date = creation_date;
    data.free_date = free_date;
    data.whoisserver = whoisserver;
    data.registrar = registrar;
    data.domains = [];
    FOREACH ns;     
    item = {};
    item.server = server;
    data.domains.push(item);
    END;
    result = {};
    result = data;
   
%]

Example result:

{
    "registered": 1,
    "query": "a-parser.com",
    "free_date": "none",
    "expire_date": "25.02.2022",
    "registrar": "PDR Ltd. d/b/a PublicDomainRegistry.com",
    "domains": [
        {
            "server": "demi.ns.cloudflare.com"
        },
        {
            "server": "vern.ns.cloudflare.com"
        }
    ],
    "creation_date": "25.02.2012",
    "whoisserver": "whois.crsnic.net"
}

To make the "Initial text" and "Final text" options available in the Task Editor, you need to activate "More options".

Obtaining the domain registrar​

Add the Results Constructor and select the source from the drop-down list: $p1.data. Select the type: RegEx Match. In the Regular Expression field, enter the regular expression: Registrar:\s*(.+) and save it to the registrar variable. Add to the Result Format: $query - $registrar\n
