Summary

Tata Communications (India access network)

India · AI-generated

isp broadband india

TATA-AS is held by Tata Communications Ltd — the company that grew out of VSNL, India's former international-gateway monopoly. Despite the famous name, this particular ASN is not the global backbone; it carries Indian end-user access space.

What it's used for

  • Subscriber and customer connectivity inside India. The reverse DNS is unambiguous about what lives here: pools like mum-cdma.dialup.vsnl.net.in, cdma-delhi.vsnl.net.in and del-cdma.dialup.vsnl.net.in, alongside static customer assignments named static-pune, static-delhi, static-kolkata and static-ttsl-hyderabad (TTSL being Tata Teleservices).

Notable

This is an eyeball access network, not a carrier, and two things settle it. First the naming: dialup and cdma pools are dynamic subscriber address space, and the static-<city> blocks are fixed assignments to broadband and small business customers — both are customer-facing, not backbone. Second the topology: RIS sees 47 announced IPv4 prefixes totalling 180,480 addresses, no IPv6, and only 1 observed neighbour. A wholesale carrier peers with hundreds to thousands of ASes; a single observed neighbour means this AS sits behind Tata's transit, as an access network hanging off the group's backbone rather than being it.

Note that cdma here names the access technology, not the customer type — it was Tata's wireless-broadband last mile (the Indicom/Photon EVDO dongles and fixed wireless terminals), which served ordinary homes and small offices.

Interesting

Addresses in this AS geolocate to specific Indian metros, and the PTRs say which: Mumbai, Delhi, Pune, Hyderabad and Kolkata all appear by name in the hostnames.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
