Nameservers, WHOIS snapshots: 92 WHOIS/RDAP snapshots that listed nameservers, 2023-11-18 to 2026-06-19 (who.is archive). A change is placed between the nearest observations on either side, from whichever source made them; where the two sources disagree, both are shown.
Hatched = the span we hold records for. A coloured bar runs only between observations that named the same registrar or operator; nothing is assumed in between.
Each mark sits at the first observation of the new state; its bracket runs back to the last observation of the old one.
