Summary

Centrul Tehnic Comercial Alfa SA

Moldova, Republic of · AI-generated

business moldova small

CTC-ALFA-AS is operated by Centrul Tehnic Comercial Alfa SA.

What it's used for

  • The space carries a single IPv4 prefix, 185.212.9.0/24, with the netname CTC_ALFA_SA and registrant SC ITNS. NET SRL.
  • The AS announces 256 IPv4 addresses across 1 prefix and maintains 3 observed neighbours, a ratio consistent with a small-scale business or internal corporate network rather than a transit provider.
  • Traffic from this AS represents the internal network infrastructure of a commercial entity based in Chisinau, Moldova.

Notable

  • The RDAP registrant for the announced prefix is SC ITNS. NET SRL, which differs from the AS holder Centrul Tehnic Comercial Alfa SA, suggesting the address space may be leased or managed by a separate technical entity.
  • The address inventory consists of a single /24 block with no IPv6 prefixes announced.

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 1,775 prefixes, as published 2026-10-11. 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.
