Summary

Zavarovalnica Sava

Slovenia · AI-generated

insurance business corporate

ZAVMB-DD is operated by Zavarovalnica Sava, d.d.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames ZAV-SAVA-SI and ZAVMB-NET registered to Zavarovalnica Sava, d.d.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal business operations for a major Slovenian insurance company, including office workers and internal systems.

Notable

  • Registrants for both announced prefixes agree with the announcer, listing Zavarovalnica Sava, d.d. as the holder.
  • Zavarovalnica Sava was formed in 2016 through the merger of Zavarovalnica Maribor, Zavarovalnica Tilia, and Velebit, which explains the ZAVMB handle derived from the former Zavarovalnica Maribor.
  • The inventory consists of two /24 blocks, 91.223.189.0/24 and 91.232.239.0/24, with no IPv6 prefixes announced.

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.
