Transit ARIN
Summary
Tata Communications
tier-1 transit backbone
Tata Communications operates a major Tier 1 backbone (TATA COMMUNICATIONS) with an exceptionally large submarine-cable and international footprint.
What it's used for
- Global IP transit and wholesale connectivity, with especially strong reach into India, Asia, Africa, and across the world's undersea cable systems.
Notable
- A Tier 1 network reaching the whole internet via peering.
- Descends from India's VSNL and the acquired Teleglobe international carrier, giving it one of the widest global cable footprints.
Interesting
- Tata claims its network touches a large share of the world's internet routes; it's a frequent transit hop on intercontinental paths.

Classification and threat
Transit Tier-1 or major backbone carrying other networks’ traffic.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
