In any presidential transition — especially those that see control of the nation's highest office move from one major party to the other there are bound to be extensive changes at federal agencies that eventually lead to extensive changes in many regulations.

The vast majority of regulatory changes will be tucked away in pages of the Federal Register, and only affect certain industries. Most Americans won't see these rules.

However, with the internet being such a big part of daily commerce and leisure, there's one potential regulatory change that could affect practically every small business and most American households.

In February 2015, the Federal Communications Commission (FCC) passed its Open Internet rules, which governed the internet in the U.S. under net neutrality and as a utility under Title II of the 1996 Telecommunications Act. Net neutrality, quite simply, is the principle that all legal data on the internet should be treated equally, regardless of internet service provider or the type of data accessed.

As the administration of President Donald Trump begins today, the days of this policy could be numbered despite being upheld by a federal appeals court in June 2016.

The 2015 decision to regulate the internet as a utility came after years of court actions, and mostly party-line Commission votes. Given FCC Chairman Tom Wheeler's resignation (which is custom for the Commission when the presidency changes parties) and Trump's power to appoint members to the Commission, it's easy to envision where 3-2 votes on the Democratic side flip to the Republicans.

Current Republican FCC Commissioner Michael O'Rielly told an audience at the conservative Free State Foundation about a month after Trump's election, "Foremost in many minds is the need simply to undo the more harmful policies adopted by the current Commission."

O'Rielly and fellow Republican Commissioner Ajit Pai the prohibitive favorite to be named Wheeler's successor as chair were both outspoken opponents of the Open Internet rules and represented the two votes against the policy in 2015. Furthermore, according to Fortune's Aaron Pressman, all but one of Trump's known FCC transition team picks is on record as opposing net neutrality rules.

And while the FCC is an unelected regulatory body, those in favor of rolling back net neutrality now have a powerful ally on Capitol Hill.

Rep. Marsha Blackburn (R-Tenn.) was recently named chairwoman of the House Energy and Commerce Committee's Communications and Technology Subcommittee, which handles telecom and other tech issues. Blackburn is arguably the No. 1 voice against net neutrality in Congress, and she has introduced legislation in each of the last three congressional terms to block the FCC from implementing net neutrality rules.

According to the Morning Consult, Blackburn is seeking both a "legislative fix" for net neutrality as well as an update to the Telecommunications Act to prevent utility classification.

While the political indications are that net neutrality won't be the law of the internet for too much longer, some aren't so sure.

"Trump himself has made a big deal out of promoting small business growth, and startup tech companies stand to gain the most from an official net neutrality position," Ed Oswald wrote in Digital Journal. "Upstart broadband providers might be best served by lobbying Trump directly to leave the regulations alone, or at least mostly intact."

Yet it already appears that some telecom companies may be in violation of current net neutrality regulations as a new administration takes office.

AT&T, Verizon and T-Mobile have been engaging in "zero-rating" practices that don't count data used on select apps against a customer's data cap, thereby favoring certain types of data. And while that raised the alarms of President Barack Obama's FCC in its final days, it's less likely that the new composition of the commission will have addressing zero-rating as a priority.

A number of federal agencies will inevitably change as the new administration takes office. But the changes at the FCC and in telecom policy in general could affect the vast majority of Americans in some way.
