Summary

Golem Tech

Slovakia · AI-generated

isp cable dsl slovakia

The AS handle GOLEMTECH-AS is held by Golem Tech s.r.o.

What it's used for

  • The address space carries residential and business connectivity, evidenced by the reverse DNS record host255.net209.golemtech.sk and the netname SK-GOLEM-20150504.
  • The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, maintaining 26 observed neighbours; this ratio of modest address space against a significant number of peers indicates a regional access provider rather than a transit hub.

Notable

  • The RDAP registrant GOLEM TECH s.r.o. aligns directly with the AS holder, confirming consistent ownership of the 185.98.208.0/22 block.
  • The address inventory consists of a single contiguous IPv4 /22 block and one IPv6 /29, representing a compact and unified corporate estate.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
