Summary

DXC Technology

United Kingdom · AI-generated

business security uk enterprise

The AS handle VISTORM-AS is held by DXC Technology.

What it's used for

  • The address space carries enterprise infrastructure, evidenced by the netname DXC-Technology and registrants including DXC Technology IPADDR Team and Enterprise Services Information Security UK Limited.
  • The AS announces 1280 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio indicating an internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, listing DXC Technology IPADDR Team, Enterprise Services Information Security UK Limited, and DXC Technology Abuse-C Team for all prefixes.
  • The address inventory consists of three distinct IPv4 blocks: 193.19.196.0/23, 194.125.246.0/23, and 195.22.158.0/24, all located in the United Kingdom.

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 1,782 prefixes, as published 2026-10-16. 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.
