Summary
Telefônica Brasil (Vivo Fibra)
isp residential eyeball fiber dsl
Telefônica Brasil (AS26599) — the fixed-network ASN of Vivo, Brazil's largest
telecom operator, carrying its Vivo Fibra home broadband.
What it's used for
- Fibre and DSL home internet for tens of millions of Brazilian households.
Notable
- A very large "eyeball" network: addresses here are Brazilian home connections, commonly behind carrier-grade NAT, not servers.
- This is the fixed broadband ASN, distinct from Vivo's mobile network ([AS27699](https://asn.ipinfo.app/AS27699)).
Interesting
- Vivo is the consumer brand of Telefônica Brasil, making AS26599 one of the most frequently seen residential-ISP origins in Brazilian traffic.
