AS18881 Telefonica Brazil contact

Hello! I tried to contact AS18881, because some of their IPv6 networks are not propagated to AS3320. I used the addresses in the whois, but got no reply and the issue persists. This affects 2804:1b1:c000::/35 and others. Can anybody give a hint how to contact them? -- kind regards Marco

Sadly, I didn't receive a reply.

You can try csa.cgpcarriers.br@telefonica.com carriers.br@telefonica.com csa.cgpcarriers@ATENTO.com.br However, they require a circuit number. Maybe they can give you a valid contact number. Em sex., 6 de jun. de 2025 às 21:07, Marco Moock via NANOG < nanog@lists.nanog.org> escreveu:
