Summary

DXC Technology (US Latin America)

United States · AI-generated

enterprise legacy

Autonomous System 4237 (CSC-IGN-FTW-AS4237) is registered to DXC US Latin America Corporation, part of DXC Technology, the IT services and outsourcing company.

What it's used for

  • Corporate and managed-services networking for DXC and the client environments it runs on their behalf.

Notable

  • Enterprise and outsourced-IT address space rather than consumer space. Addresses here typically front managed infrastructure operated for DXC's customers.
  • The CSC in the handle refers to Computer Sciences Corporation, one of the two predecessor companies that merged to form DXC Technology in 2017. Handles like this routinely outlive the company that requested them.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
