Summary

JUPO

Slovakia · AI-generated

business slovakia ipv6

The AS handle is JUPO and the holder is JUPO spol. s r.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname SK-JUPO-20191125 and registrants including Marek Cabak and Oskar Hruska.
  • The network announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale business or internal corporate estate rather than a transit or large access provider.
  • Traffic from this AS consists of office workers and internal business endpoints for the Slovakian entity.

Notable

  • Registrants agree with the announcer, listing JUPO spol. s r.o. alongside individual contacts Marek Cabak and Oskar Hruska.
  • The address inventory is compact, consisting of two /24 IPv4 blocks and a single /32 IPv6 prefix, all located in Slovakia.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
