Internet service provider / ISP
プロバイダ（ISP） purobaida
The company that connects an access line to the internet and may provide IPv6, authentication, email, security and support services.
A fibre product may bundle line and ISP in one contract, offer a list of selectable ISPs, or require a separate ISP contract. The access-line name and the ISP name are therefore not always the same.
Compare IPv6 IPoE availability, supported router, congestion handling, support language, email-address portability, optional security, minimum term and cancellation process. Marketing maximum speed alone does not identify the evening performance at your address.
