Summary

Grupo-SMS USA, LLC

United States of America · AI-generated

hosting business datacenter

The AS handle GRUPO-SMS is held by Grupo-SMS USA, LLC.

What it's used for

  • The address space is primarily registered under netnames GRUPO-SMS and GRUPO-SMS-USA, indicating a corporate or datacenter estate.
  • The AS announces 17,664 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining only 7 observed neighbours.
  • This high address-to-neighbour ratio suggests the network functions as an access or hosting provider rather than a transit carrier.

Notable

  • Most registrants align with the announcer, specifically Grupo-SMS USA, LLC, though one prefix is registered to Cox Communications Inc. and another to American Registry for Internet Numbers.
  • The address inventory is finely subdivided into multiple /21, /22, and /24 blocks, consistent with internal corporate segmentation for a datacenter or business provider.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
