Summary

Slovakia · AI-generated

cable isp residential slovakia

SATRO is operated by SATRO s.r.o., a Slovak cable television and internet service provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS records pointing to satronet.sk (e.g., 88-80-247-254.satronet.sk).
  • The AS announces 21,504 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 29 observed neighbours; this ratio of moderate address space against a significant number of peers indicates a regional access network rather than a pure transit provider.

Notable

  • All four announced IPv4 prefixes share the registrant SATRO s.r.o. and netnames beginning with SK-SATRO, confirming the address space is owned and operated by the same entity announcing the AS.
  • The address inventory consists of four distinct IPv4 blocks of varying sizes, including two /19s, one /20, and one /22, alongside a single /32 IPv6 prefix.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
