business poland content

The AS handle CURRENCYONESA is held by Currency One S.A.

What it's used for

  • The address space carries business infrastructure, evidenced by netnames CurrencyOne and registrants CURRENCY-ONE RIPE Administrators and ATMAN NOC.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 6 observed neighbours, a ratio consistent with a business or content provider rather than a transit hub.

Notable

  • Registrants differ between prefixes: 5.252.200.0/23 is registered to CURRENCY-ONE RIPE Administrators, while 212.91.18.0/24 is registered to ATMAN NOC, suggesting distinct operational histories or leased space.
  • The inventory consists of two small IPv4 blocks totaling 768 addresses, with no IPv6 prefixes announced.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,781 prefixes, as published 2026-10-16. 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.
