Programmatically

You can import the resolver from other python modules/scripts.

Installed via PIP

from dns_resolver import resolve, resolve_ipv4, resolve_ipv6

resolve('superstes.eu')
# list(['89.43.33.99', '2a05:8280:f:42ea::3'])

resolve_ipv4('superstes.eu')
# list(['89.43.33.99'])

resolve_ipv6('superstes.eu')
# list(['2a05:8280:f:42ea::3'])

Copied

Per example if the scripts are saved in the same directory.

ls .
> dns_resolver.py
> program.py

from dns_resolver import resolve, resolve_ipv4, resolve_ipv6

resolve('superstes.eu')
# list(['89.43.33.99', '2a05:8280:f:42ea::3'])

resolve_ipv4('superstes.eu')
# list(['89.43.33.99'])

resolve_ipv6('superstes.eu')
# list(['2a05:8280:f:42ea::3'])
