Summary

TRUF d.o.o.

Serbia · AI-generated

isp serbia residential

TRUF-AS is operated by TRUF d.o.o.

What it's used for

  • The address space carries residential and business internet services, evidenced by the netname TRUF and the registrant TRUF d.o.o. for the majority of prefixes, alongside KBCONLINE for a smaller block.
  • The AS announces 13,312 IPv4 addresses across 3 prefixes while maintaining only 2 observed neighbours, a ratio that indicates an access network providing connectivity to end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and static IP endpoints for local businesses in Serbia, consistent with the operator's role as a regional internet service provider.

Notable

  • Registrants for the two largest prefixes align with the AS holder, while the 91.234.132.0/22 block is registered to PRIVREDNO DRUSTVO ZA PROIZVODNJU PROMET I USLUGE KBC ON LINE DOO under the netname KBCONLINE, suggesting a distinct operational entity or legacy allocation within the same AS.
  • The inventory is composed of three distinct IPv4 blocks with no announced IPv6 prefixes, reflecting a purely IPv4-based infrastructure.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
