Recorded DNS history

Registry presence: first seen 2026-04-28; last seen 2026-09-07. These are appearances in our domain registry, not domain registration dates or earlier DNS values.

This history starts with saved RR captures. Provider market-share charts are aggregate context, not this domain’s DNS history. Dates identify observations; no continuous validity between them is implied. Equivalent RR states are combined, ignoring response TTL and capture-time changes. Up to 30 distinct RR states and 60 dated captures are retained within a per-domain byte limit.

No earlier different RR snapshot is available for comparison.
