About this network

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.
