isp residential mexico cable

AS28447 is operated by OnFiber SA de CV.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries pointing to onfiber.com.mx (e.g., ip-38-158-202-128.onfiber.com.mx).
  • The AS announces 1280 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are ONFIBER SA DE CV, matching the AS holder, while the prefix 38.226.104.0/24 is registered to Cogent Communications, LLC under the netname COGENT-A.
  • The address inventory consists of four distinct IPv4 blocks, including a /23 and three /24s, alongside a single /32 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,772 prefixes, as published 2026-10-15. 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.
