Net::DNS - parser resolves domains to IP addresses
Overview
Net::DNS – collects DNS records for a domain name. Automated bulk resolving of a domain database, checking domain availability.A-Parser functionality allows you to save parsing settings for the Net::DNS parser for future use (presets), set parsing schedules, and much more.
Saving results is possible in any form and structure you need, thanks to the built-in powerful Template Toolkit templating engine, which allows applying additional logic to results and outputting data in various formats, including JSON, SQL, and CSV.
Collected data
- List of IP addresses
- DNS server used for a successful request
- DNS record of any type (output as JSON, making it convenient to retrieve individual parameters)
Use cases
- Resolving domain databases
- Checking domain availability
Queries
You should specify a list of domains as queries, for example:
a-parser.com
yandex.ru
google.com
vk.com
facebook.com
youtube.com
Output results examples
A-Parser supports flexible result formatting thanks to the built-in Template Toolkit templating engine, which allows it to output results in any form, as well as in structured formats like CSV or JSON.
Default output
Result format:
$query: $ip ($ips.format('$ip, '))\n
The result displays the domain and its IP addresses:
youtube.com: 173.194.70.136 (173.194.70.136, 173.194.70.190, 173.194.70.93, 173.194.70.91, )
google.com: 46.28.247.98 (46.28.247.98, 46.28.247.89, 46.28.247.84, 46.28.247.108, 46.28.247.119, 46.28.247.114, 46.28.247.88, 46.28.247.94, 46.28.247.99, 46.28.247.109, 46.28.247.93, 46.28.247.104, 46.28.247.113, 46.28.247.118, 46.28.247.123, 46.28.247.103, )
facebook.com: 173.252.110.27 (173.252.110.27, )
a-parser.com: 176.9.9.90 (176.9.9.90, )
vk.com: 87.240.143.244 (87.240.143.244, 87.240.131.120, )
yandex.ru: 93.158.134.11 (93.158.134.11, 213.180.193.11, 213.180.204.11, 77.88.21.11, 87.250.250.11, )
Saving in SQL format
Result format:
[% "INSERT INTO dns VALUES('" _ query _ "', '" _ ip _ "', '" _ ips.format('$ip, ') _ "')\n" %]
Result example:
INSERT INTO dns VALUES('vk.com', '87.240.190.67', '87.240.190.67, 87.240.190.72, 87.240.190.78, 93.186.225.208, 87.240.137.158, 87.240.139.194, ')
INSERT INTO dns VALUES('a-parser.com', '176.9.9.90', '176.9.9.90, ')
INSERT INTO dns VALUES('yandex.ru', '5.255.255.50', '5.255.255.50, 77.88.55.50, 77.88.55.88, 5.255.255.5, ')
INSERT INTO dns VALUES('facebook.com', '157.240.19.35', '157.240.19.35, ')
INSERT INTO dns VALUES('youtube.com', '172.217.171.238', '172.217.171.238, ')
Dump results to JSON
General output format:
[% IF notFirst;
",\n";
ELSE;
notFirst = 1;
END;
obj = {};
obj.query = query;
obj.ips = p1.ips;
obj.json %]
Initial text:
[
Final text:
]
Result example:
[
{"ips":[{"ip":"176.9.9.90"}],"query":"http://a-parser.com/"},
{"ips":[{"ip":"172.217.173.78"}],"query":"http://google.com/"},
{"ips":[{"ip":"77.88.55.60"},{"ip":"77.88.55.66"},{"ip":"5.255.255.55"},{"ip":"5.255.255.60"}],"query":"http://yandex.ru/"},
{"ips":[{"ip":"172.217.25.14"}],"query":"http://youtube.com/"},
{"ips":[{"ip":"87.240.190.78"},{"ip":"93.186.225.208"},{"ip":"87.240.137.158"},{"ip":"87.240.139.194"},{"ip":"87.240.190.67"},{"ip":"87.240.190.72"}],"query":"http://vk.com/"},
{"ips":[{"ip":"157.240.196.35"}],"query":"http://facebook.com/"}
]
To make the "Initial text" and "End text" options available in the Task Editor, you need to activate "More options".
