Resetting DNS

Background

When accessing the internet, a device will use DNS (Domain Name System) servers to translate domains (e.g. unimelb.edu.au) into global Internet Protocol (IP) addresses. These are typically matched to the router's DNS configuration when your device connects to a network, however they can be set manually.

Some DNS servers may be more suitable for your needs than others. Changing your DNS server can help increase web browsing speed, provide extra security, or allow anonymity. Unless you have a reason for using a different DNS server, it is probably best to use the servers automatically provided by your Internet Service Provider (ISP) or network administrator.
