Summary

Argentina · AI-generated

datacenter colocation business infrastructure

The AS handle CIRION TECHNOLOGIES ARGENTINA S.A. is held by Cirion Technologies.

What it's used for

  • The address space carries static business and data center infrastructure, evidenced by reverse DNS entries such as 190-216-228-64.dia.static.centurylink.com.ve and registrant netnames like NET-8-243-248-0-21 and LPL-141-CL-1905-67-73-128.
  • The AS announces 3328 IPv4 addresses and 15 IPv6 prefixes against 16 observed neighbours, a ratio consistent with a regional infrastructure provider rather than a large-scale transit carrier.

Notable

  • Registrants include CTL Venzuela, CTL LATAM, and Level 3 Venezuela S.A., reflecting the historical ownership of the address space prior to the operator's rebranding.
  • Cirion Technologies is the rebranded entity of Level 3 Communications' Latin American operations, which was acquired by CyrusOne and subsequently renamed to reflect its focus on data center and colocation services.
  • The inventory consists of five IPv4 prefixes and ten IPv6 prefixes, with the largest IPv4 block being 8.243.248.0/21.

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 1,773 prefixes, as published 2026-10-13. 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.
