Fadi Chehade, chief executive of the Internet Corporation for Assigned Names and Numbers, said opponents of the new oversight system might be deliberately trying to delay the transition set for 30 September.
"ICANN has been waiting for this political window to open for 16 years," Chehade told AFP as the group began a four-day meeting in Singapore.
"We don't know what factors could affect the political window," he said, adding "we do know that in 2016 there is a heavy political process in the United States".
"Therefore the oxygen that is available to certain items may be very easily consumed by the electoral process."
The next US presidential election and related polls for Congress and state governors will be held on 8 November 2016.
ICANN is in charge of assigning Internet domain names and the numbering codes that lie behind online addresses. It has been overseen by the US government since its inception in 1998, under a contract that expires by end-September this year.
Some countries like China and Russia have called for a solely inter-governmental body to oversee ICANN in the future. Critics say such a model would provide a powerful tool to repressive regimes.
Within the United States, some lawmakers have also criticised the move to cede control of the group, citing the possibility that it could be detrimental to the national interest.
Washington has insisted that it would only hand over the reins to a globally representative group of governments, civil society and businesses.
Chehade said the Internet community was aware of efforts by some parties to derail such a "multi-stakeholder" approach by deliberately delaying the transition, but did not mention names.
"Those who are trying for their own purposes to delay this transition, make no mistake, we know that the most powerful political tool to kill something is to simply delay it," he said.
In an interview with AFP last week, Chehade conceded that the US might have to extend its control beyond September amid continued bickering among stakeholders, including governments, over the replacement regulatory regime.
Steve Crocker, the chair of ICANN's board of directors, said on Monday in Singapore "there is no precise, absolute stroke of midnight deadline".
"But there is a general sense of haste and to some degree, some urgency."
