DNS (the internet's address book)
In Turkish: DNS (internetin adres defteri)
The system that turns a site name like example.com into the number address of its server. Whoever runs your DNS sees which sites you look up.
By default your DNS is run by your internet provider or the network you are on. If a hostile network or a changed router setting points you to a bad DNS server, it can send you to a fake copy of a real site even though you typed the right name.
What to do
- Check that your router's DNS setting has not been changed to an unknown address.
- Consider a private DNS option on your phone from a provider you trust.
- Be wary if a familiar site suddenly looks different or shows warnings.
