The Internet protocols are all public and are developed by IETF, not DARPA. https://www.ietf.org/ https://www.ietf.org/ The Internet is operated by Internet service providers, not DARPA. The U.S. government role in directly operating the Internet ended in 1995 with the shutdown of NSFNet. The ISPs buy hardware from private companies that implement the public Internet protocols. That doesn't mean that there aren't backdoors of various kinds in Internet infrastructure, but whatever backdoors exist aren't likely to exist by virtue of DARPA's role in funding the original research.
