berkas1/dnspropagation repository overview

⁠dnspropagation

Simple CLI utility to check propagation of DNS records using multiple DNS servers.

⁠Installation

pip install dnspropagation

⁠Usage

In the most simple form you can just specify type of record and domain name:

dnspropagation a google.com
# OR
docker run berkas1/dnspropagation a google.com

It will check entries for a given type and domain name using five default public nameservers. It returns a human-readable colorful table. You can use --json or --yaml parameters to make it machine-readable.

⁠Custom DNS servers

You can either supply custom DNS server to query using the --server parameter, which can be used multiple times:

dnspropagation --server 1.1.1.1 --server 8.8.8.8 a google.com
# OR
docker run berkas1/dnspropagation --server 1.1.1.1 --server 8.8.8.8 a google.com

OR you can add a yaml-formatted list of servers. This has to follow given format (as can be seen in this⁠ file) and be supplied to the utility using the --custom_list parameter.

⁠Expected results

You can expect a value to be returned by DNS servers. If this value is returned, its color will be green. Otherwise the value will be shown red.

⁠Filtering DNS servers

When using the default DNS servers or a custom list, you can limit which servers you want to query using parameters --country and --owner. Both can be used multiple times. When used, the AND operation is used.
