AS28549 is operated by Cablemas Telecomunicaciones SA de CV.

What it's used for

  • The address space carries residential and business connectivity, evidenced by registrant netnames such as 131.161.244.0 - 131.161.247.255 and 177.236.0.0 - 177.239.255.255 assigned to Cablemas.
  • The AS announces 19456 IPv4 addresses across 6 prefixes and 7 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to Cablemas Telecomunicaciones SA de CV, though 201.139.76.0/22 is registered to Cable y Comunicacion de Campeche, S.A. de C.V.
  • The address inventory is composed of a mix of /18, /22, /23, and /24 blocks, with the largest allocation being 201.161.192.0/18.

Reputation

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 1,779 prefixes, as published 2026-10-22. 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.
