What it's used for

  • The space carries the corporate network for an accounting and advisory firm, identified by the netname ALFA-ACCOUNTS-EN-ADVISEURS and registrant aaff Accountants en Advies B.V.
  • The inventory consists of 256 IPv4 addresses in a single /24 prefix (91.199.59.0/24) with 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.

Notable

Reputation

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
