Summary

YPF S.A.

Argentina · AI-generated

business corporate argentina

AS27655 is operated by YPF S.A., the Argentine state-owned oil and gas company.

What it's used for

  • The address space is registered under the netname 200.1.118.0 - 200.1.118.255 with registrant YPF S.A., indicating a corporate internal network.
  • The AS announces 256 IPv4 addresses across 1 prefix (200.1.118.0/24) and has 1 observed neighbour, a ratio consistent with a single-site or small-scale internal corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant YPF S.A. matches the AS holder name exactly.
  • The address inventory consists of a single /24 block, which is typical for a corporate network requiring a modest amount of public IP space for internal services or legacy systems.

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 1,779 prefixes, as published 2026-10-21. 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.
