About this network

PEGASO PCS is the registered holder of the mobile network operated by Telefónica México, which sells service under the Movistar brand. The handle is a fossil of Pegaso PCS, the Mexican mobile operator Telefónica took over in the early 2000s.

What it's used for

• Mobile (cellular) internet access for Movistar subscribers across Mexico — roughly 71k IPv4 addresses spread over 100+ prefixes.
• Reverse DNS confirms the operator: subscriber-style names under optele.net (pc020.optele.net) alongside gateway names under telefonica.net.mx.

Notable

• Mobile address space, not fixed broadband or hosting — the administrative and abuse contacts resolve to Telefónica Móviles México's IP-addressing team in Cuajimalpa, Mexico City.
• Do not read "Pegaso PCS" as an independent carrier today; the brand is long gone and only the registry handle survives.

Interesting

• The registry object still carries the pre-acquisition name more than two decades on, a common pattern where a merged carrier never bothered to rename its ASN.
