Summary

UB330.net

Slovenia · AI-generated

business slovenia hosting

The AS handle UB330-NET2 is held by UB330.net d.o.o.

What it's used for

  • The address space carries corporate infrastructure and leased blocks, evidenced by netnames SI-UB330-20150320, SI-UB330-19960626, and SI-UB330-20041213, alongside the distinct IC4-NET4 block.
  • The AS announces 1,536 IPv4 addresses and 1 IPv6 prefix across 4 IPv4 prefixes, with 5 observed neighbours, indicating a small-scale business or internal corporate network rather than a transit provider.
  • Reverse DNS entries such as ntp.ub330.net and icnet4.intercoding.net confirm the space hosts specific service endpoints and third-party infrastructure.

Notable

  • Registrants for the majority of the space align with the announcer, listing UB330.net d.o.o. and UB330 RIPE, while the 23.226.112.0/24 block is registered to INTERCODING.
  • The inventory includes a US-based prefix (23.226.112.0/24) registered to a different entity, suggesting leased or acquired address space distinct from the primary Slovenian holdings.
  • The address inventory is finely subdivided into four distinct IPv4 prefixes, reflecting a segmented corporate estate.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
