isp residential slovakia cable

DATASYS is operated by DATASYS - edoma.net s.r.o., a Slovak internet service provider based in Trnava.

What it's used for

  • The address space carries residential and small business traffic, evidenced by the reverse DNS record 128.50.142.185.datasys.sk and the netname SK-DATASYS-20160307.
  • The AS announces 1280 IPv4 addresses across 3 prefixes and maintains 10 observed neighbours, a ratio consistent with a regional access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for cable and DSL services provided by edoma.net within Slovakia.

Notable

  • Two of the three announced prefixes are registered to DATASYS - edoma.net s.r.o., while the third, 84.245.95.0/24, is registered to SWAN, a.s. under the netname SK-SWAN-20050316.
  • The address inventory is small and fragmented, consisting of two /23 blocks and one /24 block, all located in Slovakia.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
