Summary

HCL Technologies UK Limited

United Kingdom · AI-generated

business corporate uk

The AS handle HCLUK-AS-MS is held by HCL Technologies UK Limited.

What it's used for

  • The space carries corporate traffic for HCL Technologies, evidenced by the netname CUSTOMERS and the registrant Abuse-C Role associated with the single announced prefix.
  • The inventory consists of 256 IPv4 addresses within 1 prefix, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour, this AS functions as a small, isolated corporate estate rather than a transit or access network.
  • Traffic from this AS represents internal corporate operations for HCL Technologies' UK subsidiary, including office workers and internal service endpoints.

Notable

  • The registrant Abuse-C Role for the prefix 193.164.28.0/24 aligns with the announcer HCL Technologies UK Limited, indicating direct ownership of the address space.
  • HCL Technologies Limited, the parent company, is an Indian multinational technology company headquartered in Noida, Uttar Pradesh, which was spun out of HCL Group.
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a specific site or departmental allocation within a larger corporate infrastructure.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
