Net::DNS - domain resolver to IP addresses
Net::DNS parser overview
Net::DNS collects DNS records of a domain name. Automated mass domain resolving, domain availability check.A-Parser functionality allows saving parsing settings for Net::DNS parser for further use (presets), setting up parsing schedule and much more.
Results can be saved in any format and structure you need, thanks to the built-in powerful Template Toolkit which allows applying additional logic to the results and outputting data in various formats, including JSON, SQL and CSV.
List of collected data
- List of IP addresses
- Used DNS server in case of a successful request
- Any type of DNS record (displayed in JSON format, which allows conveniently obtaining their individual parameters)
Use cases
- Resolving a mass domain base
- Checking domain availability
Query examples
The list of domains should be specified as queries, for example:
a-parser.com
yandex.ru
google.com
vk.com
facebook.com
youtube.com
As a result, the domain and its IP addresses are displayed. Example:
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, )
Output options
A-Parser supports flexible formatting of results thanks to the built-in Template Toolkit, which allows it to output results in any form, as well as in a structured form, for example, CSV or JSON.
Saving in SQL format
Result format:
[% "INSERT INTO dns VALUES('" _ query _ "', '" _ p1.ip _ "', '" _ p1.ips.format('$ip, ') _ "')\n" %]
Example of the result:
INSERT INTO dns VALUES('vk.com', '87.240.190.67', '87.240.190.67, 87.240.190.72, 87.240.190.78, 93.186.225.208, 87.240.137.158, 87.240.139.194, ')
INSERT INTO dns VALUES('a-parser.com', '176.9.9.90', '176.9.9.90, ')
INSERT INTO dns VALUES('yandex.ru', '5.255.255.50', '5.255.255.50, 77.88.55.50, 77.88.55.88, 5.255.255.5, ')
INSERT INTO dns VALUES('facebook.com', '157.240.19.35', '157.240.19.35, ')
INSERT INTO dns VALUES('youtube.com', '172.217.171.238', '172.217.171.238, ')
Dumping results in JSON
Result format:
[% data = {};
data.query = query;
data.ips = p1.ips; %]$data.json\n
Example of the result:
{"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/"}
