Summary

DTnet Detva

Slovakia · AI-generated

telecom residential slovakia

The AS handle DTNETSK-AS is held by DTnet Detva s.r.o.

What it's used for

  • The address space carries subscriber endpoints, evidenced by reverse DNS entries such as host-0.185-122-53.dtnet.sk and host-255.185-133-61.dtnet.sk.
  • The network announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a local access network rather than a transit provider.
  • Traffic from this AS consists of residential and small business internet access for subscribers in the Detva and Lučenec regions of Slovakia.

Notable

  • Registrants for both announced IPv4 prefixes (SK-DTNET-20151020 and SK-DTNET-20151230) are listed as DTnet Detva s.r.o., matching the AS holder.
  • The address inventory is compact, consisting of two /22 blocks and a single /31 IPv6 prefix, typical of a regional telecommunications operator.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
