Summary
Telefónica de Argentina
isp legacy
AS4926 is held by Telefónica de Argentina, the Argentine incumbent operator descended from the 1990 privatisation of the state telephone monopoly ENTel.
What it's used for
Telefónica de Argentina is one of the country's two dominant fixed-line and broadband carriers, selling ADSL and fibre internet, telephony and TV to homes and businesses under consumer brands the company has cycled through over the years. It is an eyeball network.
Notable
This particular AS is a small legacy remnant rather than the operator's main routing identity. It announces only a handful of /24s carved out of a single legacy /16, while the bulk of Telefónica de Argentina's subscriber address space rides other, larger AS numbers. Large incumbents often accumulate several ASNs across decades of mergers and address acquisitions and keep the old ones alive for specific netblocks.
Treat it as one of Telefónica de Argentina's networks, not as the Telefónica de Argentina network.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
