Documents to open in this workflow

This order suggests a starting point; revisit a step if identifiers, dates or versions disagree. Access and reuse terms depend on each service.

ICANN Lookup
Query public domain, IP network and ASN registration data through RDAP.
What to record
Exact name, dated RDAP response, statuses, queried server and any links from an official site.
Source-specific check
Redacted fields, intermediaries and hosts often prevent identification of the actual operator.
Open source portal
Wayback Machine
Compare dated web-page captures and retain a link to a viewable version.
What to record
Original URL, capture URL, capture time and any missing or incomplete page elements.
Source-specific check
An archive shows a retrieved version at a time, not content accuracy or its creation date.
Open source portal

Matching condition

Keep exact domain, page URL and capture timestamp; separate current observations from archives.

If results disagree

A registrant change does not automatically date authorship changes; seek dated attribution.

Output to produce

Timeline of observations and captures.

Separate documentary evidence, demonstrated links between documents and remaining inference. State the owner and review trigger.

Frequently asked questions

What link should be checked before matching results?

Keep exact domain, page URL and capture timestamp; separate current observations from archives.

What if sources appear to contradict each other?

A registrant change does not automatically date authorship changes; seek dated attribution.

Do the listed portals provide independent confirmation?

Not necessarily. Identify the producer and underlying document. Two interfaces distributing one item can check transcription but do not establish a fact independently twice.
