AS2914

AS2914 is NTT's global Tier-1 backbone, registered to NTT America, Inc. under ARIN and operated as the NTT Global IP Network (GIN). It is a single dual-stack autonomous system spanning the Americas, Asia, Europe, and Oceania, and NTT describes it as operating the largest Transpacific network — a detail that explains why AS2914 frequently appears on intercontinental routes between Asia and the rest of the world. CAIDA AS Rank places it #5 globally, with a customer cone of roughly 22,660 ASNs, ~564,129 prefixes, and ~1.23 billion addresses, a transit degree near 1,509, and over a thousand direct customers. NTT is known for strong routing hygiene and operational transparency: it deployed RPKI-based BGP origin validation and publishes one of the industry's most extensive sets of BGP communities for traffic engineering. Its peering policy is selective, as expected for a settlement-free Tier-1. In 2024 it was the other party in Cogent's (AS174) de-peering, which raised latency for single-homed European customers. As a backbone it originates little end-user traffic, so abuse signals belong to downstream customers.
