The US Justice Department has said that internet service providers should be allowed to charge for priority traffic. The agency said it was opposed to "network neutrality", the idea that all data on the net is treated equally.
The comments put the agency at odds with companies such as Microsoft and Google, who have called for legislation to guarantee equal access to the net.
The agency submitted its comments to the Federal Communications Commission, which is investigating net access.
Several US internet service providers (ISPs), including AT&T and Verizon, have previously said that they want to charge some users more money for certain content.
This has particularly become an issue with the rise of TV and film download services.
The Justice Department said imposing net neutrality regulations could hinder development of the internet and prevent ISPs from upgrading networks.
