Summary

SMS solutions SIA

Latvia · AI-generated

sms business latvia

The AS handle CDR-AS51347 is held by SMS solutions SIA.

What it's used for

  • The space carries SMS infrastructure, evidenced by the reverse DNS entry robosms-64.robosms.com and the registrant netname CDR-NET.
  • The network announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, dedicated business network rather than a transit or large access provider.
  • Traffic from this AS consists of SMS gateway and messaging service endpoints, consistent with the operator's business in SMS solutions.

Notable

  • The registrant SMS solutions SIA matches the AS holder, with the netname CDR-NET associated with the same entity.
  • The address inventory consists of a single /24 block (91.247.72.0/24), representing a compact and focused allocation for the service.

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 1,849 prefixes, as published 2026-10-30. 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.
