Summary
TESATEL, s.r.o.
isp legacy
TESATEL-AS is the network of TESATEL, s.r.o., a regional internet and cable-television operator based in Žilina, Slovakia. It sells broadband and TV to households, notably to the apartment blocks of the city's Hájik housing estate.
What it's used for
Residential access. The AS announces a single 31.170.64.0/19 (~8,192 addresses) plus one IPv6 prefix, with one observed neighbour — a single-homed local ISP, which is the normal shape for a Slovak municipal-scale operator. The address count is a good match for a subscriber base of a few thousand households in one city.
Notable
- No PTRs came back on the addresses sampled inside the
/19. That is not proof the zone is undelegated; it just means the sampled addresses did not answer. Theresidentialcall therefore rests on the operator's business (internet + cable TV sold to housing cooperatives) rather than on reverse-DNS naming, and is held at medium confidence. - One prefix, one upstream, one IPv6 prefix. There is no wholesale or transit surface here, and no hosting-style naming in evidence.
- First seen in BGP in 2011, well after the AS number itself would have been issued — the
31.170.0.0/16range is post-exhaustion RIPE space, so the current inventory is much younger than the AS.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
