What it's used for

  • The address space carries corporate infrastructure for a Turkish investment firm, identified by netnames TR-ALB-20151222 and PUSULA-YATIRIM-MENKUL-DEGERLER.
  • The inventory consists of 1280 IPv4 addresses across 2 prefixes, with 2 observed neighbours, indicating a small, self-contained business network rather than a transit or access provider.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
