Kazakhstan · AI-generated

transit telecom kzt

The AS handle RETN-KZ-AS is held by RETN KZ Ltd.

What it's used for

  • The address space carries infrastructure for a telecommunications provider, with the netname RETN-KZ-30102023 and registrant RETN KZ Ltd.
  • The inventory consists of 256 IPv4 addresses within a single prefix, 139.45.211.0/24, and 0 IPv6 prefixes.
  • With 1 observed neighbour, the low neighbour count relative to the address block suggests a focused transit or peering role rather than a large-scale access network.
  • Traffic from this AS represents connectivity services, including IP transit, Ethernet, VPN, and remote peering to major Internet Exchange Points, as provided by RETN.

Notable

  • The registrant RETN KZ Ltd matches the AS holder, confirming consistent ownership of the announced space.
  • RETN operates as a third-party backbone operator in Kazakhstan, offering high-capacity data transmission and global Internet services.
  • The address inventory is compact, consisting of a single /24 block, which aligns with a specialized transit provider rather than a mass-market residential ISP.

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 1,773 prefixes, as published 2026-10-13. 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.
