For buyers contracting authority
The scoping call with 72411000 is access versus everything that rides on top of it. A contracting authority picks this code when the deliverable is the connection: a broadband service, a leased line, dedicated internet access for a government network, or an arrangement to exchange IP traffic. If the contract is really about operating a website, that is World wide web (www) site operation host services (72415000), even when the supplier also supplies the link.
The second boundary is telecom. Internet access frequently sits next to voice, mobile and data-transmission lines in the same procurement, and authorities often default the lot to Telephone and data transmission services (64210000) or the broader Telecommunications services parent (64200000). Tag 72411000 when internet connectivity is the main purpose of the lot; tag the telecom code when it is bundled under a wider voice-and-data contract. Where one tender mixes access with hosting or applications, set the primary CPV code by the dominant deliverable, not by the whole bundle.
