Unclassified ARIN
Summary
Katun Corporation
business corporate small
KATUN-AS-1 is operated by Katun Corporation.
What it's used for
- The address space is registered under the netname
USAKTN01for Katun Corporation, indicating a corporate or business allocation. - The AS announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio consistent with a small internal corporate estate or site-specific network rather than a transit or access provider.
Notable
- The RDAP registrant for both announced prefixes is Katun Corporation, which aligns with the AS holder identity.
- The inventory consists of two contiguous IPv4 blocks: 206.221.168.0/23 and 206.221.170.0/24.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
