Summary

Bollnas energi AB

Sweden · AI-generated

municipal energy sweden small

HELSINGENET is operated by Bollnas energi AB, a Swedish municipal energy company.

What it's used for

  • The address space is registered under netnames SE-HELSINGENET-20170331 and Bollnas-NET, indicating internal corporate and municipal network infrastructure.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and 3 IPv6 prefixes, with only 1 observed neighbour, suggesting a small, isolated internal network rather than a transit or access provider.

Notable

  • Registrants include both Bollnas energi AB and Bollnas kommun, reflecting the municipal ownership structure of the operator.
  • The inventory consists of a single /22 block and a single /24 block in IPv4, alongside three /48 and one /29 IPv6 prefixes, forming a compact and segmented address 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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
