Summary

Tata Communications Lanka

Sri Lanka · AI-generated

telecom enterprise wholesale sri-lanka

The AS handle TCLL-AS-AP is held by Tata Communications Lanka Ltd.

What it's used for

  • The address space carries static IP addresses for enterprise and wholesale services, evidenced by reverse DNS entries such as 59.163.244.128.static.vsnl.net.in and 14.140.61.64.static-Colombo.vsnl.net.in.
  • The AS announces 768 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a regional access or enterprise network rather than a major transit provider.

Notable

  • Registrants for both announced prefixes are listed as IRT-TATACOMM-IN with the netname TATAC-LANKA, aligning with the registrant Tata Communications Lanka Ltd.
  • The operator was formerly known as VSNL Lanka before being rechristened as Tata Communications Lanka Ltd, a subsidiary of Tata Communications Limited.
  • The inventory consists of two distinct IPv4 blocks: 59.163.244.0/23 and 14.140.61.0/24, with no IPv6 prefixes currently announced.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
