Summary

Servicio Meteorológico Nacional

Argentina · AI-generated

government meteorology argentina

AS27674 is operated by Servicio Meteorológico Nacional.

What it's used for

  • The address space is registered under the netname 200.16.116.0 - 200.16.116.255 with the registrant SERVICIO METEOROLOGICO NACIONAL, indicating a dedicated government meteorological service network.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (200.16.116.0/24) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant SERVICIO METEOROLOGICO NACIONAL matches the AS handle and registry holder exactly, confirming direct ownership of the announced space.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a minimal footprint typical of a specialized national agency.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
