Can you filter the " Pan resolved domain name"

Hi

it is great project for research.

Analyzing-Datasets of sonar.fdns_v2, i found some domain is " Pan resolved domain name" .
For example 0000000000.cn, any sub domain of 0000000000.cn (aas.sdfw.0000000000.cn) can get the ip. Maybe there are meaningless data in the scan result.

The dateset is big, if can store them according to suffix of domain, maybe it is easy to download when olny research some country domain.
