Summary

CSCOM

Argentina · AI-generated

business argentina small

The AS handle CSCOM is held by FABRONI CLAUDIO ANTONIO.

What it's used for

  • The space carries a single IPv4 block with the netname 200.110.208.0 - 200.110.215.255, registered to the same individual as the AS holder.
  • The network announces 2048 IPv4 addresses across 1 prefix and has 0 IPv6 prefixes. With only 1 observed neighbour, the low neighbour count against a small address block suggests a limited or internal network rather than a transit provider.

Notable

  • The RDAP registrant FABRONI CLAUDIO ANTONIO matches the AS holder name exactly.
  • The address inventory consists of a single /21 block (200.110.208.0/21) located in Argentina.
  • The reverse DNS sample shows one PTR record 254.213.cscom.com.ar, consistent with the AS handle.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
