AS7674 — GOFORS NTT Communications Corporation

AS7674 announces 3 IPv4 prefixes covering 1,280 addresses and 1 IPv6 prefixes.

About this network

GOFORS is a small, old NTT network. It is registered today to NTT DOCOMO BUSINESS, Inc. — the company that was NTT Communications until its 2025 rename — and carries carrier infrastructure rather than any customer-facing service.

What it's used for

• Three prefixes in 192.47.0.0/16 (192.47.160.0/24, 192.47.170.0/23, 192.47.172.0/23), about 1,280 addresses in total, plus one IPv6 /48.
• Reverse DNS is entirely in jp.ntt.net, NTT's carrier network domain, with router and gateway names such as ote-gw.jp.ntt.net alongside plain address-derived hostnames. There are no subscriber pools, no hosting tenants and no enterprise customer domains anywhere in the sampled space.

Notable

• Deliberately left unclassified. This is network plumbing: too small to be a service network, and not the AS anyone reaches NTT through. NTT's actual retail and transit networks are AS4713 (OCN) and AS2914 (the global backbone). Assigning this AS an eyeball or hosting label would attach a kind it does not carry.
• The GOFORS netname itself is undocumented outside the registry, and no honest expansion of it is available — so none is offered here.

Interesting

• JPNIC records the 192.47.170.0/24 assignment as dating from August 1992, which puts this among the earlier surviving Japanese address registrations still in active use.
