The development of technology has an effect on aspects of education that have an impact on learning activities. The utilization of learning media on computer networks is still incomplete so that it has an impact on understanding how computer networks are installed theoretically. Mobile phones today have many features that can be utilized for playing games, watching videos, listening to music, personal assistants, searching for information, GPS, and much more. One of the interesting technologies that can be developed on mobile phones is Augmented Reality. Augmented Reality (AR) is a technology that combines two-dimensional or three-dimensional virtual objects into a three-dimensional real environment and then projects them in real-time. This study discussed the design of Android applications using augmented reality technology used in computer networking subjects. (Augmented Reality Network) describes the description of computer network equipment displayed in 3D. The method used is Research and Development (R&D). The results of the learning media trial conducted on respondents obtained a score with an average percentage rate of 84.5% with the description of this AR product worthy of use.
