Summary
Pegaso PCS (Telefónica Movistar México)
mobile legacy
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 undertelefonica.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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
