isp residential cable dsl

AS28435 is operated by Tamayo Telecom, a Mexican cable and DSL provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as ip-38-224-221-0.tamayotelecom.mx and 174.128.azaelgarcia.net.
  • The AS announces 3840 IPv4 addresses and 17 IPv6 prefixes against 8 observed neighbours, a ratio consistent with an access network rather than a transit provider.

Notable

  • Registrants include Cogent Communications, LLC for the 38.224.220.0/22 block, while other prefixes are registered to JAVIER TAMAYO GARCIA and Tamayo Telecom, S.A. de C.V..
  • The inventory includes a mix of /22, /23, and /24 IPv4 prefixes, with the largest being 38.224.220.0/22, 45.189.148.0/22, and 153.51.240.0/22.

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 1,782 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.
