Summary

Perftech d.o.o.

Slovenia · AI-generated

hosting legacy

PERFTECH-SLOVENIA-AS is Perftech d.o.o., a Ljubljana-based IT services, systems integration and data-centre company.

What it's used for

  • Data-centre and hosting services: colocation, virtual servers, hosted mail and filtering, DNS and related managed infrastructure for business customers.
  • Reverse DNS across the announced space resolves under perftech.si, mostly in a dcs-<address>.perftech.si form, which reads as data-centre server addressing rather than subscriber pools.

Notable

  • The company's own history describes it as an early builder of internet networks in Slovenia that later sold ADSL and wireless access, which would explain how a mid-sized IT firm came to hold a low-numbered ASN and a /19 of legacy address space.
  • Whatever its ISP past, the current use of the space is hosting and enterprise services rather than consumer access: Perftech runs a certified data centre in Ljubljana and lists banks and payment organisations among its customers.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
