Unclassified ARIN
Summary
Tata Communications (America) Inc.
transit legacy
The US arm of Tata Communications, the Indian-headquartered global carrier. The
ARIN record sits with Tata Communications (America) Inc. in Herndon, Virginia.
What it's used for
- Carrier and transit services on Tata's global IP backbone: this AS originates a modest set of prefixes rather than serving end users, and the space it carries is drawn from Tata's own address ranges.
- Tata Communications' main global backbone is a separate, much larger AS; this one is a US-registered network within the same group.
Notable
- The ASN was registered with ARIN in 1996, well before Tata's involvement: the US business traces back through Teleglobe and VSNL, which Tata acquired in the 2000s. The registrant name was updated to Tata Communications, so the number carries a lineage older than its current holder.
- Be careful not to conflate this AS with Tata's Indian consumer or enterprise networks; it is the American entity.
