AS12823 KAPPATECH-AS
Unclassified RIPE
Summary
UMKA (Kappatech)
business hosting
A /24 whose netname is not a name at all, but a registry object identifier.
What it's used for
- A small Serbian business network. 256 addresses in one IPv4 prefix, two observed BGP neighbours, and no IPv6 announced.
Notable
- The whole inventory is
193.53.106.0/24, registered to UMKA d.o.o. - The netname field reads
ORG-UA405-RIPE. - The AS handle is
KAPPATECH-AS; the holder is UMKA d.o.o. - First observed in the routing archive in February 2012.
- Three addresses were sampled and none returned a name.
Interesting
ORG-UA405-RIPEis an organisation handle: an identifier the registry generates when an organisation record is created, of the formORG-plus initials plus a sequence number. It belongs in the field that links a block to its owner, not in the field that names the block. Somebody filling the form pasted the handle into the wrong box, and it has been the network's public name ever since.- The AS is named for one company and held by another, with no dated netname to show when the handover happened. Small allocations change hands quietly; the AS number and the netname often keep pointing at whoever set things up first.
- Two neighbours and a single /24 registered in the 193 range, which is old European space, suggests a block that predates its current holder. New assignments of that size come from more recently released ranges.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
