thanks for this project.. Massdns commands include, for example, --interval. this command means timeout value. When using shuffledns I want to use the --interval command and increase the value. The more timeout values ​​given, the more accurate the results. For this, additional features should be introduced.

Currently predefined massdns cmd is used at https://github.com/projectdiscovery/shuffledns/blob/master/pkg/massdns/process.go#L93

There are more tweaks to massdns scans that can be achieved using an additional flag to accept massdns optional commands.

-mcmd, -massdns-cmd        additional massdns commands to use with scan

Example:

shuffledns -mcmd '-i 100'
