Summary

Capital One (Europe) Plc

United Kingdom · AI-generated

banking corporate uk

The AS handle C1UK-AS is held by Capital One (Europe) Plc.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the netname UK-CAPITALONEBANK-20010326 and registrants including C1UK-TECH and C1UK-ADMIN.
  • The AS announces 4096 IPv4 addresses within a single prefix (217.169.160.0/20) and maintains 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, listing C1UK-TECH, C1UK-ADMIN, Capital One (Europe) Plc, and C1UK-ABUSE for the sole announced block.
  • The address inventory consists of a single /20 block, representing a finely subdivided internal corporate network typical of a major financial institution's European operations.

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 1,849 prefixes, as published 2026-10-30. 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.
