Summary

ABLE agency, s.r.o.

Czechia · AI-generated

business czech small

The AS handle ADA-NET-AS is held by ABLE agency, s.r.o.

What it's used for

  • The space carries a single IPv4 block with netname CZ-ABLE-20091005 and registrant ADA-NET Hostmasters; ABLE agency, s.r.o.
  • The inventory consists of 4096 IPv4 addresses in one prefix (95.140.240.0/20) and one IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained network rather than a transit or large access provider.
  • As a staffing agency operating in the Czech Republic, the traffic from this AS is primarily office workers and internal business endpoints.

Notable

  • The registrant ADA-NET Hostmasters; ABLE agency, s.r.o. aligns with the AS holder, confirming direct ownership of the address space.
  • The address inventory is a single contiguous /20 block, typical of a small corporate or service provider estate.

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 1,781 prefixes, as published 2026-10-16. 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.
