Summary

CTC Astana

Kazakhstan · AI-generated

telecom business kazakhstan

CTCASTANA is operated by CTC Astana Ltd.

What it's used for

  • The address space carries corporate and VoIP infrastructure, evidenced by netnames CTC-ASTANA, KZ-VOIP-20060705, and STS-ASTANA.
  • The AS announces 4,352 IPv4 addresses across 6 prefixes and maintains 10 routing neighbours, a ratio consistent with a regional business or enterprise network rather than a large-scale residential access provider.
  • Traffic from this AS consists of business communications, VoIP signalling and media, and internal corporate backhaul for the operator's clients in Kazakhstan.

Notable

  • Registrants include CTC ASTANA LTD and Open Media Group LLC, with Network Kazakhstan LLC appearing on the KZ-VOIP-20060705 block, indicating a mix of owned and potentially leased or partner-managed space.
  • The inventory consists of six distinct IPv4 prefixes with no IPv6 announcements, reflecting a legacy IPv4-only deployment.

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 1,784 prefixes, as published 2026-10-19. 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.
