NTT DoCoMo (DOCOMO) — Japan's largest mobile carrier, part of the NTT group.

What it's used for

  • Mobile data for a very large Japanese subscriber base, plus DoCoMo's related online services.

Notable

  • A large "eyeball" network; addresses here are typically Japanese mobile devices, often behind carrier-grade NAT, so geo is coarse.
  • One of Japan's three big carriers alongside KDDI (au) and SoftBank.

Interesting

  • DoCoMo pioneered mobile data early with its i-mode service in the late 1990s, years ahead of the smartphone era.
