Expired .com domains in education and courses

Stable niche related to taekwondo in Indonesia. The school name changed over time (Star Fighter -> South Sky), but the focus remained the same.

Stable niche related to Bach flower therapy training (D-BBDE9C), traceable from 2015 to 2026. No niche change recorded.

From 2015 to 2023, the domain was consistently used as a Brazilian school website (educational niche). After the drop, starting in 2025, it hosted a Chinese VPN service — the niche has changed drastically.

Franchise of the children's swimming school "Krol" (a site about a swimming club franchise). The niche has been stable from 2017 to 2025, but was interrupted by a long downtime with redirects (2019–2022) and unstable periods in 2023–2025.

Stable niche of the Japanese cooking school «キッチンスタジオ モグ» in Shizuoka, with no niche changes throughout its history (2012–2024).

Consistent niche throughout the site's lifetime (2012–2022): a commercial phone/video English learning service with native US speakers, targeting a Korean audience. No niche changes recorded.

Originally the site was likely related to education or online courses ("D-31A308"). Since 2020 the niche is unclear because the Wayback Machine only saves blank or repetitive page titles, which may indicate downtime, parking, or technical pages with no content.

The entire stable history (from 2015 to 2021) is a personal site/blog under the name Max Dufrechou; no niche changes detected. Before 2015 — just a title placeholder "D-212A79.com". The final niche before the drop was a personal brand; if the links pointed to the name/personal site, it matches the profile, but for a PBN in a different niche it will be irrelevant.

Stable niche of a dog training school ("Hundeschule Fiffikus") from 2006 to 2018. Since 2023, the content has disappeared, and the site serves blank pages without page titles, indicating a drop and downtime.

Stable niche — firearms training. No niche change detected; the site kept the same page title throughout its entire history.

Website of a Japanese English language school (Ian's English House) with a specific location in Nagano. The niche remained stable throughout its active life (2016–2025), except for technical "DOMAIN ERROR" glitches, with no niche changes.

Originally (2007-2009) the domain was used as a portal for "Gay-Bi-Lesbian Network" (LGBTQ+ niche). Since 2012, the niche fully shifted to "Global Business Learning" (business education), which remained until the domain dropped.
