The national Internet domain of the Republic of Serbia is .rs. Until recently, the domain of the former Yugoslavia .yu was still in use, and links with that extension are still common on the Internet, despite being obsolete. If you click on a .yu link it will not work, but try the address again with .rs, with or without the prefix .co or .org.
Internet Cafes and Hotspots
There are many Internet cafés in Belgrade and other large towns and tourist sites in Serbia, as well as a great number of wireless Internet hotspots where you can access the Internet free of charge via your laptop.
