Summary

Danske Bank

Denmark · AI-generated

finance enterprise

A Danish bank's seven prefixes, with three different netname conventions across them.

What it's used for

  • Corporate and banking connectivity. 9,472 addresses in seven IPv4 prefixes with three observed BGP neighbours and no IPv6 announced.

Notable

  • Four blocks share netname DK-DDB-990628, a date written YYMMDD.
  • 185.218.228.0/22 is DK-DDB-20170824, the same scheme with a four-digit year.
  • 212.93.56.0/24 is DK-DDB-8273492, where the trailing number is not a date at all.
  • 193.111.64.0/23 breaks the pattern entirely with netname SAMNETS.
  • None of the eighteen sampled addresses returned a reverse name.

Interesting

  • Three conventions in one inventory is twenty years of registry practice in a single company's records. The 990628 block predates the change that made everyone spell years in full, the 2017 block follows it, and 8273492 is somebody's internal ticket or account number arriving where a date was expected.
  • DDB is Den Danske Bank, the older form of the name that the legal entity still carries even though the business trades as Danske Bank. Registry records preserve the version of a name that was current when the paperwork was signed.
  • SAMNETS reads as a shared or joint network, the sort of name given to space used with somebody else rather than by the bank alone.

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.
