Summary

Dolphin International Inc. (DOLPHIN internet)

Japan · AI-generated

isp legacy

DOLPHIN is Dolphin International Inc., an independent Japanese internet service

provider based in Hachioji, Tokyo, trading as DOLPHIN internet (din.or.jp /

din.ad.jp).

What it's used for

  • Dial-up-era-turned-broadband subscriber access, plus hosting and domain services for its members.

Notable

  • Dolphin is one of the many small, long-lived regional ISPs that make up the long tail of the Japanese internet: a modest address footprint, a couple of upstream transit providers, and a subscriber base rather than a datacentre.
  • Member web pages and mail accounts are hosted on the same space, so the network mixes a little content hosting into what is otherwise access address space.
