Question
If the WHOIS records match the main Scorecard domain attribution, why is the domain missing from the related domain list?
Answer
Scanners may treat the assets as unknown or as belonging to a different owner due to case sensitivity and formatting inconsistencies observed in the WHOIS records. Case-sensitive record matching is by design.
It may be necessary to manually add related domains to your scorecard. Please see the following article on adding assets to your Digital Footprint.
