What is DNS?
Domain Name System (DNS) is the protocol that converts domain names (uri.edu, for example) into Internet Protocol (IP) Addresses (i.e 184.108.40.206), or vice versa. This conversion process, called resolution, is done by a DNS Server. Most computers should automatically be configured to use URI’s DNS Servers via Dynamic Host Configuration Protocol (DHCP).
Why am I blocked?
You are using DNS Servers that are not provided by URI. These servers are also listed on various blacklists. Using untrusted DNS servers is a potential security risk and could allow attackers to steal personal information. The DNS settings are usually changed by a virus (such as the DNS Changer Trojan) without the user’s consent.
How do I fix this?
You need to change your DHCP Settings to obtain DNS Server information. After fixing your DNS Settings, you should also run a virus/malware scan in safe mode to remove any infections. After rebooting, verify that the DNS settings are still correct.
You will need to call the Helpdesk to be unblocked. Additionally, if you require any help, contact the Helpdesk by calling (401) 874-4357 or by emailing firstname.lastname@example.org.

To get online at URI, your IP address DNS settings must be obtained automatically.
In very rare instanced, you may need to edit the Domain Name Services (DNS) settings on a MacOS machine.
