isp residential cable argentina

AS27865 is operated by Tecnologia WorkOut S.A., commonly known as TWKO.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as host2900.twko.com.ar and host30254.twko.com.ar.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 7 observed neighbours, indicating a regional access provider rather than a transit hub.

Notable

  • Registrants for both announced IPv4 prefixes (170.239.28.0/22 and 190.103.80.0/22) match the AS holder, Tecnologia WorkOut S.A.
  • The address inventory consists of two /22 blocks in the 170.239.0.0/16 and 190.103.0.0/16 ranges, typical of a mid-sized regional ISP in Argentina.

Reputation

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: 447 networks and 1,843 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.
