Summary

ASTANA Technologies

Czechia · AI-generated

business czech small

The AS handle ASTANA is held by ASTANA Technologies s.r.o.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname CZ-ASTANA-20180125 and reverse DNS entries pointing to astana-tech.net.
  • The inventory consists of 512 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale internal or business network rather than a transit or large access provider.
  • Traffic from this AS represents internal corporate operations for ASTANA Technologies, a Czech-based entity.

Notable

  • Registrants align with the announcer, listing ASTANA NOC and ASTANA Technologies s.r.o. for the primary prefix.
  • The address inventory is compact, consisting of a single /23 block and a /31 IPv6 prefix, consistent with a small organizational footprint.

Reputation

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
