AS12837 ONECLAUDLAB-NET 1 Claud Lab network
Unclassified RIPE
Summary
1 Cloud Lab
hosting business isp
A Slovak company announcing Ukrainian space, with the word "cloud" misspelled in its AS name.
What it's used for
- A hosting and connectivity provider. 3,072 addresses in two IPv4 prefixes, one IPv6 prefix, and five observed BGP neighbours; the announced blocks are seen in Ukraine.
Notable
- The inventory is
31.24.208.0/21and91.196.196.0/22, plus2a03:6306::/32. - The AS handle reads
ONECLAUDLAB-NET 1 Claud Lab network; the registered holder is 1 Cloud Lab s.r.o. - Netnames are
SK-1CLOUDLAB-20110228andORG-CLS14-RIPE. - Six addresses were sampled and none returned a name.
Interesting
- The AS name spells it
CLAUDin both the handle and the descriptive text, while the company record spells itCLOUD. A typo entered once at registration is permanent in practice: fixing it means an update nobody is required to make, so the misspelling is now the network's official public name. - One netname is
ORG-CLS14-RIPE, an organisation handle generated by the registry, pasted into the field meant for a block's name. This is the second holder in this range to make exactly that mistake, which says the two fields sit close enough together on the form to be confused. - The company form
s.r.o.and theSK-netname prefix are Slovak, while the addresses are seen announced from Ukraine. Where a network is registered, where it is incorporated and where its traffic lands are three separate questions, and this AS answers them differently.

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 2026-10-27, 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: 447 networks and 1,852 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.
