Summary

Islandsbanki

Iceland · AI-generated

banking business iceland

ISLANDSBANKI-AS1 is operated by Islandsbanki hf.

What it's used for

  • The address space carries corporate infrastructure for a major Icelandic bank, with netnames IS-ISLANDSBANKI and IS-ISLANDSBANKI2 registered to Islandsbanki NOC.
  • The AS announces 2048 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, internal systems, and web/API endpoints for the bank's operations.

Notable

  • All registrants agree with the announcer, listing Islandsbanki NOC for the prefixes 46.28.152.0/22, 46.28.156.0/23, and 46.28.158.0/23.
  • The address inventory is finely subdivided into three contiguous IPv4 blocks and a single IPv6 prefix, consistent with site-by-site segmentation for an internal corporate network.

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 1,843 prefixes, as published 2026-11-01. 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.
