Summary

KONFER networks

Slovakia · AI-generated

isp residential cable dsl

KONFER is operated by KONFER networks, a Slovak internet service provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as static.93.254.KONFER.net and 254.166.144.185.dyn.zemnet.sk.
  • The AS announces 3072 IPv4 addresses across 2 prefixes and maintains 27 upstream or peer neighbours, a ratio consistent with a regional access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints served via cable and DSL infrastructure in Slovakia.

Notable

  • Registrants for both announced prefixes (SK-KONFER-20100421 and SK-KONFER-20160324) are listed as David Kondicz trading as KONFER networks, matching the AS holder.
  • The address inventory is composed of two distinct IPv4 blocks, one acquired in 2010 and the other in 2016, with no IPv6 prefixes currently announced.

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 1,768 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.
