Domains can move between providers for ordinary reasons, but large unexplained infrastructure changes can invalidate older observations.
Record the observation window
Capture the hostname, resolved addresses, network owner and time without assuming control from hosting alone.
Infrastructure data is dynamic and should never be presented without a date.
Compare meaningful transitions
Look for coordinated changes in DNS, certificates, redirects and page content.
A single IP change may be routine, while several simultaneous changes deserve a fresh review.
Account for shared platforms
Content delivery networks and shared hosting can place unrelated domains on the same infrastructure.
Network proximity is not evidence that two Mars Market claims share an operator.
Investigate unexplained reversals
Rapid moves between unrelated providers may reflect mitigation, migration or instability.
Document possible explanations as uncertainty rather than selecting one without support.
Reset stale conclusions when needed
If the infrastructure supporting a previous result has changed materially, repeat the relevant checks.
Historical evidence remains useful but should not automatically validate the current destination.
