As a transitional strategy, they were effective, giving commercial network operators a bridge from the Internet's beginnings as a government-funded academic experiment, to the modern Internet of many private-sector competitors collaborating to form a network-of-networks, anchored around the Internet Exchange Point

s we know today.

This was particularly timely, coming hard on the heels of the ANS CO+RE controversy, which had disturbed the nascent industry, led to congressional hearings, resulted in a law allowing NSF to promote and use networks that carry commercial traffic, prompted a review of the administration of NSFNET by the NSF's Inspector General (no serious problems were found), and caused commercial operators to realize that they needed to be able to communicate with each other independent of third parties or at neutral exchange points.

Today, the phrase "Network Access Point" is of historical interest only, since the four transitional NAPs disappeared long ago, replaced by modern IXPs, though in Spanish-speaking Latin America, the phrase lives on to a small degree, among those who conflate the NAPs with IXPs
