Summary

Reiknistofa bankanna

Iceland · AI-generated

business it financial iceland

RB is operated by Reiknistofa bankanna hf.

What it's used for

  • The address space carries internal IT infrastructure for Icelandic financial institutions, evidenced by the netnames IS-RB1-20130701 and RB-Farice and the reverse DNS record meet.rb.is.
  • The AS announces 1024 IPv4 addresses across 3 prefixes with 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic consists of internal communications, web endpoints, and IT services supporting the banking sector in Iceland.

Notable

  • Registrants for the announced prefixes are consistent with the AS holder, listing Reiknistofa bankanna hf. for 185.29.196.0/23 and 185.29.199.0/24, and Abuse-C Role for 185.29.198.0/24.
  • The address inventory is compact, consisting of one /23 and two /24 blocks within the 185.29.0.0/16 range, with no IPv6 prefixes announced.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
