Retrieving Dns Records Using Python
September 16, 2016 • Python • 2 minutes to read • Edit
You can retrieve DNS records using dnspython
package. You can install the package using pip install dnspython
.
Gist can be found at https://gist.github.com/akshaybabloo/2a1df455e7643926739e934e910cbf2e
The problem with this package is that you cannot retrieve all the records at a time so a quick and dirty alternative is to put them in for
loop. Few record names in this list (ids
) raise an exception, for example ANY
, this is because there is no DNS record called ANY
.
