This paper and its actual research began in 1384 Iranian Calendar (2005) and that time it was one of the first projects that considered internet and ethnography in Iran to be methodologically inter-related. Since we wanted to provide a base for similar studies in Iran, we chose a number of groups for our anthropological study, and we worked on the way these groups operated in virtual space. This line of research originated from the fact that internet as pervasive media has special characters that provide special situation in human communication and therefore provide a field for ethnographic research. We also kept in mind the fact that because global users also operate in the virtual space and create joint communities; therefore, socio-cultural processes must take place there. We have realized that people and groups go to the virtual for variety of purposes and that makes them to change to ethnographic subjects, suitable for our ethnographic observation. In this paper, five Iranian ethnic groups and their internet activities will be studied. We will examine their functions in internet from ethnographic view. One of important reasons we selected these groups is the importance of ethnographic issues in today’s world and especially in Iran. Iran has a number of ethnic groups whose inclusion and national unity are conditioned by political sustainability that depends of how these groups exercise their national identity in internet.
