Summary
Claro S.A. (Embratel)
isp transit legacy
Autonomous System 4230 is operated by Claro S.A., the Brazilian arm of América
Móvil, and carries the network that was built as Embratel, Brazil's long-standing
long-distance and backbone carrier.
What it's used for
- Fixed broadband and business connectivity for millions of subscribers in Brazil.
- IP transit and backbone routing for downstream networks, making this one of the larger carrier networks in South America.
Notable
- Very large eyeball and carrier network: it originates several million IPv4 addresses, concentrated in the Brazilian 187.x, 189.x, 200.x, and 201.x ranges, and peers at Brazilian and international exchanges.
- A mixed network. Much of the space is residential, but a meaningful share is business access and transit, so an IP here is not automatically a home user.
Interesting
- Embratel was Brazil's state telecom monopoly before privatisation. The name survives in the network's registration long after the Claro rebrand.
