Using the university's DNS servers improves the security of our university networks by –

• Enhancing threat protection– our DNS helps block harmful websites, keeping you and your data safer online

• Ensuring consistent security– using one trusted DNS service allows us to protect everyone on the network

• Improving overall visibility– helps us respond to cyber threats more quickly and effectively

If you are using university-owned, unmanaged or self-managed devices, or a personal device to connect to the university network, please follow these instructions to check your settings and ensure your devices are set up to obtain DNS and DHCP settings automatically, to ensure your Windows device has the recommended configuration.

If you are using an alternative, third-party DNS and DHCP server, you may experience a loss of connectivity to the internet, to university networks and network services. You will need to reset your iOS device to obtain its DNS and DHCP settings automatically, ensuring your iOS device has the recommended configuration.
