"We are looking under the hood," said Wheeler in a statement.
Netflix's agreements have been controversial; the company complains that it shouldn't have to pay ISPs directly to improve consumers' streaming speeds. Comcast and Verizon argue that Netflix should bear the cost of the upgrades the ISPs must make to accommodate Netflix's rising traffic levels.
ISP defenders say that "paid peering" is a common feature in the part of the Internet that carries data from its originating source, like Netflix, to the doorstep of broadband providers charged with carrying that data to its final destination — your computer or tablet. Despite that, Netflix says that most of its peering agreements involve no money changing hands.
In a statement, Comcast said it welcomed the probe.
We have long published our peering policies … and are open to discussions about further disclosures," the company said. "We also have voluntarily shared a vast array of information about our peering and interconnection practices with the FCC."
Wheeler wants to get to the bottom of this. And although he isn't about to regulate this part of the Web, which is considered separate from net neutrality because it doesn't have to do with "last-mile" connections to the home, he still intends to do some fact-finding.
"We are making inquiries across the board," he told reporters Friday.
